Update to FindFace Multi 2.1

Tip

If you use our product FindFace Security deployed on Ubuntu 18.04, upgrade it to FindFace Multi 1.2 and then update it to FindFace Multi 2.1.

If you use FindFace Multi 2.0, update it to FindFace Multi 2.1 by following the instruction.

The Incidents and VNS plugins, operable in FindFace CIBR, are not supported in FindFace Multi 2.1. That’s why there’s no need to enable ffsecurity_incidents, ffsecurity_vns, and ffsecurity_puppeteer plugins in the findface-multi-legacy.py configuration file after product update.

Integration with Axxon Next is included into external VMS integration in FindFace Multi 2.1 and configured through VMS integration plugin.

If you created person and car cards with custom fields in FindFace Multi 1.2 and want them to be displayed in the FindFace Multi 2.1 UI, then it is necessary to copy the CUSTOM_FIELDS section from the old configuration file in step #2 and paste it to the new configuration file in step #8.

In this section:

Update FindFace Multi 1.2 to FindFace Multi 2.1 

To update FindFace Multi 1.2 to FindFace Multi 2.1, do the following:

Create a backup copy of the old schema of the Tarantool-based feature vector database:
```
sudo cp /etc/findface-security/tnt_schema.lua /etc/findface-security/old_tnt_schema.lua
```
Starting from version 2.0, one of the most significant differences between FindFace Multi and earlier versions of the product is the structure of the Tarantool biometric database (so called meta-schema). The new structure is created as a set of spaces, while in previous versions of the product there was only one space by default in the structure of the Tarantool-based database.

Open the /etc/findface-security/config.py configuration file. Save the values of the following parameters for later use: EXTERNAL_ADDRESS, SECRET_KEY, VIDEO_DETECTOR_TOKEN, ROUTER_URL, CUSTOM_FIELDS.

sudo vi /etc/findface-security/config.py

EXTERNAL_ADDRESS = "http://172.20.77.58"
...
# use pwgen -sncy 50 1|tr "'" "." to generate your own unique key
SECRET_KEY = 'c8b533847bbf7142102de1349d33a1f6'
FFSECURITY = {
'VIDEO_DETECTOR_TOKEN': '381b0f4a20495227d04185ab02f5085f',
...
'ROUTER_URL': 'http://172.20.77.58',
...
# -- Custom model fields --
# Edit CUSTOM_FIELDS -> `human_card` section to customize human card fields.
# Edit CUSTOM_FIELDS -> `face_object` section to customize face object fields.
# Below is an example with every field type possible.

#                 'editable': False
#             }
#         ],

#                 'field': 'personid'
#             }
#         ]
#     },
#     'face_object': {
#         'items': [
#             {
#                 "field_name": "tag_name_1",
#                 "type": "string",
#                 "default": "change_me"
#             },
#             {
#                 "field_name": "tag_name_2",
#                 "type": "uint",
#                 "default": 123
#             },
#             {
#                 "field_name": "tag_name_3",
#                 "type": "bool",
#                 "default": True
#             },
#         ]
#     }
# },
}

Stop the findface-security service.

sudo systemctl stop findface-security.service

Create a backup of the Tarantool-based feature vector database in any directory of your choice, for example, /etc/findface_dump.

sudo mkdir -p /etc/findface_dump
cd /etc/findface_dump
sudo findface-storage-api-dump -config /etc/findface-sf-api.ini

To avoid port conflicts, stop and disable all services before installing a new version.

Install the FindFace Multi 2.1 instance. Don’t forget to prepare a server first:

See:
After FindFace Multi installation, stop all the containers from the /opt/findface-multi/ directory.
```
cd /opt/findface-multi/

sudo docker-compose stop
```

Open the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py configuration file and paste saved on step #2 values for the parameters EXTERNAL_ADDRESS, SECRET_KEY, VIDEO_DETECTOR_TOKEN, ROUTER_URL, and CUSTOM_FIELDS into it.

sudo vi /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py
...
# Use pwgen -sncy 50 1|tr "'" "." to generate your own unique key
SECRET_KEY = '002231ccb690586f4d33e98322c591bb'
...
SERVICE_EXTERNAL_ADDRESS = 'http://172.20.77.58'
# EXTERNAL_ADDRESS is used to access objects created inside FFSecurity via external links.
EXTERNAL_ADDRESS = 'http://172.20.77.58'
...
    # findface-video-worker authorization token
    'VIDEO_DETECTOR_TOKEN': '8977e1b0067d43f6c908d0bf60363255',
...
    # findface-video-worker face posting address,
    # it must be set to either FFSecurity EXTERNAL_ADDRESS (by default)
    # or findface-facerouter url (in some specific cases)
    'ROUTER_URL': 'http://127.0.0.1:80',

Open the old version of the findface-ntls configuration file available at /etc/findface-ntls.cfg and check it against the new version /opt/findface-multi/configs/findface-ntls/findface-ntls.yaml. Move all the custom parameters from the old version to the new one. Do the same for other components, e.g., for findface-extract-api, check /etc/findface-extract-api.ini against /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml, for findface-sf-api, check /etc/findface-sf-api.ini against /opt/findface-multi/configs/findface-sf-api/findface-sf-api.yaml, etc.
```
sudo vi /etc/findface-ntls.cfg
sudo vi /opt/findface-multi/configs/findface-ntls/findface-ntls.yaml
sudo vi /etc/findface-extraction-api.ini
sudo vi /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml
sudo vi /etc/findface-sf-api.ini
sudo vi /opt/findface-multi/configs/findface-sf-api/findface-sf-api.yaml
```
Important

Carefully check your old /etc/findface-sf-api.ini configuration file against the new /opt/findface-multi/configs/findface-sf-api/findface-sf-api.yaml one. If your shard structure differs from the default structure (different number of shards, address is other than local 127.0.0.1, etc), specified in the /opt/findface-multi/configs/findface-sf-api/findface-sf-api.yaml configuration file , we recommend contacting our support team (support@ntechlab.com) for advice.
Important

Follow these rules to transfer parameters from the old configuration file to the new one:
- If there is a new neural network model in the new configuration file, replace it with the previous one (considering that the previous model is still included in FindFace Multi 2.1), and if the previous model is missing in FindFace Multi 2.1, then do not change anything. In this case, you will have to do migration to a different neural network model.
- If a parameter had an empty value in the old configuration file, but has a certain value in the new configuration file, delete its value in the new configuration file.
- Keep as is those parameters that were not included in the old configuration file, but are present in the new configuration file.

Modify the Tarantool database structure by applying the tnt_schema.lua schema from FindFace Multi 2.1.

sudo docker run --rm --network host --volume '/opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro' docker.int.ntl/ntech/multi/multi/legacy:ffmulti-2.1.0 make-tnt-schema | sudo tee /etc/findface-security/tnt_schema.lua

Purge data from all the directories relevant to active shards.

sudo rm /opt/ntech/var/lib/tarantool/shard-*/{index,snapshots,xlogs}/*

Copy the meta-schema of the default space from the old_tnt_schema.lua configuration file to the new tnt_schema.lua configuration file, so that the old meta-schema is still available. An easy way to do it is to follow these steps:

12.1. In the /etc/findface-security/old_tnt_schema.lua file, rename the following fields:

meta_scheme --> meta_scheme_default
meta_indexes --> meta_indexes_default

12.2. In the new configuration file /etc/findface-security/tnt_schema.lua, replace the following lines at the beginning of the file:

cfg_spaces = {
  default = {
    meta_scheme = {
      -- internal.normalized_id:
      {
          default = '',
          field_type = 'string',
          id = 1,
          name = 'normalized_id',
      },
      -- internal.feat:
      {
          default = '',
          field_type = 'string',
          id = 2,
          name = 'feat',
      },
    },
    meta_indexes = {}
  },

with these ones:

dofile("/etc/findface-security/old_tnt_schema.lua")
spaces = {
 default = {
    meta_scheme=meta_scheme_default,
    meta_indexes=meta_indexes_default
  },

Navigate to the directory with Tarantool configuration file(s) /etc/tarantool/instances.available/. Import new meta-schema tnt_schema.lua into each configuration file shard-00*.lua, as in the example below.

sudo vi /etc/tarantool/instances.available/shard-00*.lua

dofile("/etc/findface-security/tnt_schema.lua")
FindFace = require("FindFace")
FindFace.start("127.0.0.1", 8104, {
    license_ntls_server="127.0.0.1:3133",
    replication = replication_master,
    spaces = spaces
 })

Remove the default configuration file FindFace.lua, generated by the findface-tarantool-server package, as it will block the restart, required on the next step.
```
sudo rm -rf /etc/tarantool/instances*/FindFace.lua
```

Restart the findface-tarantool-server shards.

TNT=$(ls /etc/tarantool/instances.enabled/ | cut -c 7,8,9)
for i in $TNT; do sudo systemctl restart tarantool@shard-$i.service ; done

Upon completion of the above steps, the shards will still keep the old galleries created within the default space, but new spaces (e.g., ffsec_body_objects_space, ffsec_face_clusters_space, and so on) will also become available.

Restore old data from the backup. The data will be restored as it existed previously: all galleries will stay within the default space.

sudo systemctl start findface-ntls.service
cd /etc/findface_dump
for x in *.json; do sudo findface-storage-api-restore -config /etc/findface-sf-api.ini < "$x"; done

Migrate galleries from the default space to new spaces:

sudo systemctl start findface-sf-api.service
sudo systemctl start nginx.service
sudo docker run --rm --network host --volume '/opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro' docker.int.ntl/ntech/multi/multi/legacy:ffmulti-2.1.0 /opt/findface-security/bin/python3 /tigre_prototype/manage.py migrate_tnt_space

Perform PostgreSQL database migrations for FindFace Multi 2.1 compatibility. Do the following:

18.1. Navigate to the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py configuration file. In the DATABASES -> default section, temporarily replace PASSWORD with the old one, used in the /etc/findface-security/config.py configuration file.

Important

Make sure to write down the password from the /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py configuration file. You will need it later.

sudo vi /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'DISABLE_SERVER_SIDE_CURSORS': True,
        'NAME': 'ffsecurity', 'HOST': '127.0.0.1', 'PORT': 5439, 'USER': 'ntech', 'PASSWORD': 'XXXXXXXXXXXXXXXX'
    }
}

18.2. In the /etc/pgbouncer/pgbouncer.ini file, add the following line to the databases section:

ffsecurity_session = dbname=ffsecurity host=localhost port=5432 user=ntech pool_mode=session pool_size=10

18.3. On the host system, perform the database migration:

sudo systemctl start postgresql.service
sudo systemctl start pgbouncer.service
sudo docker run --rm --network host --volume '/opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro' docker.int.ntl/ntech/multi/multi/legacy:ffmulti-2.1.0 /opt/findface-security/bin/python3 /tigre_prototype/manage.py migrate

18.4. Dump an existing database with PostgreSQL, installed on the host system.

cd /opt/findface-multi/
sudo -u postgres pg_dump --verbose --disable-triggers ffsecurity | sudo tee dump_ffsecurity.sql
sudo -u postgres pg_dump -t auth_group -t ffsecurity_adgroupguid -t ffsecurity_deviceblacklistrecord -t ffsecurity_ffsecauthsession -t ffsecurity_grouppermission -t ffsecurity_runtimesetting -t ffsecurity_user -t ffsecurity_user_groups -t ffsecurity_user_user_permissions -t ffsecurity_userkeyvalue -t knox_authtoken -t ffsecurity_watchlistpermission -t ffsecurity_cameragrouppermission --data-only --verbose --no-acl --no-owner --disable-triggers ffsecurity | sudo tee dump_identity_provider.sql

18.5. Back up role permissions.

sudo docker run --rm --network host --volume '/opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro' docker.int.ntl/ntech/multi/multi/legacy:ffmulti-2.1.0 /opt/findface-security/bin/python3 /tigre_prototype/manage.py dump_permissions | sudo tee permissions.csv

18.6. Change back the password, replaced in step #18.1

18.7. Stop all services.

sudo systemctl stop findface-sf-api.service
sudo systemctl stop nginx.service
sudo systemctl stop tarantool@shard-00*.service
sudo systemctl stop postgresql.service
sudo systemctl stop pgbouncer.service

18.8. Open the /opt/findface-multi/docker-compose.yaml file and copy POSTGRES_PASSWORD value to use it in further commands.

18.9. Recreate the ffsecurity database to clean it up from the default data. Paste {POSTGRES_PASSWORD} value that you previously copied in step #18.8 into the command below:

sudo docker-compose up -d postgresql
sudo docker exec -it -u postgres findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} dropdb ffsecurity"
sudo docker exec -it -u postgres findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} createdb -O ntech --encoding=UTF-8 --lc-collate=C.UTF-8 --lc-ctype=C.UTF-8 --template=template0 ffsecurity"

18.10. Restore data into the recreated ffsecurity database. Paste {POSTGRES_PASSWORD} value that you previously copied in step #18.8 into the command below:

sudo docker exec -i findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} psql --username postgres ffsecurity" < dump_ffsecurity.sql

18.11. Recreate the ffsecurity_identity_provider database to clean it up from the default data. Paste {POSTGRES_PASSWORD} value that you previously copied in step #18.8 into the command below:

sudo docker exec -it -u postgres findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} dropdb ffsecurity_identity_provider"
sudo docker exec -it -u postgres findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} createdb -O ntech --encoding=UTF-8 --lc-collate=C.UTF-8 --lc-ctype=C.UTF-8 --template=template0 ffsecurity_identity_provider"

18.12. Run migration.

sudo docker-compose up -d pgbouncer
sudo docker run --rm --network host --volume '/opt/findface-multi/configs/findface-multi-identity-provider/findface-multi-identity-provider.py:/etc/findface-security/config.py:ro' docker.int.ntl/ntech/multi/multi/identity-provider:ffmulti-2.1.0 /opt/findface-security/bin/python3 /tigre_prototype/manage.py migrate

18.13. Restore data into the recreated ffsecurity_identity_provider database. Paste {POSTGRES_PASSWORD} value that you previously copied in step #18.8 into the command below:

sudo docker exec -i findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} psql --username postgres ffsecurity_identity_provider" < dump_identity_provider.sql

18.14. Start all services.

sudo docker-compose up -d

18.15. Run the command to create records in the outbox table for watch lists and camera groups. Paste {POSTGRES_PASSWORD} value that you previously copied in step #18.8 into the command below:

sudo docker exec -i findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} pg_dump --username postgres -f cg_wl_permissions.sql -t ffsecurity_cameragrouppermission -t ffsecurity_watchlistpermission --data-only ffsecurity_identity_provider"
sudo docker run --rm --network host --volume '/opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py:/etc/findface-security/config.py:ro' docker.int.ntl/ntech/multi/multi/legacy:ffmulti-2.1.0 /opt/findface-security/bin/python3 /tigre_prototype/manage.py create_outbox
sudo docker exec -i findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} psql --username postgres -c 'TRUNCATE ffsecurity_cameragrouppermission, ffsecurity_watchlistpermission RESTART IDENTITY;' ffsecurity_identity_provider"
sudo docker exec -i findface-multi-postgresql-1 /bin/bash -c "PGPASSWORD={POSTGRES_PASSWORD} psql --username postgres ffsecurity_identity_provider < cg_wl_permissions.sql"

18.16. Restore role permissions into the identity_provider service.

sudo docker run --rm --network host -v /opt/findface-multi/configs/findface-multi-identity-provider/findface-multi-identity-provider.py:/etc/findface-security/config.py:ro -v $(pwd)/permissions.csv:/var/permissions.csv:ro docker.int.ntl/ntech/multi/multi/identity-provider:ffmulti-2.1.0 /opt/findface-security/bin/python3 /tigre_prototype/manage.py load_permissions /var/permissions.csv

18.17. Copy Tarantool gallery files, full frame photos, normalized images, and the license file. Copy files from the /opt/ntech/license/ folder into the /opt/findface-multi/data/findface-ntls/ folder, from the /opt/ntech/var/lib/tarantool/ folder into the /opt/findface-multi/data/findface-tarantool-server/ folder, from the /var/lib/findface-security/uploads/ folder into the /opt/findface-multi/data/findface-multi-legacy/uploads/ folder, from the /var/lib/ffupload/uploads/ folder into the /opt/findface-multi/data/findface-upload/uploads/ folder.

sudo cp -r /opt/ntech/license/* /opt/findface-multi/data/findface-ntls/
sudo cp -r /opt/ntech/var/lib/tarantool/* /opt/findface-multi/data/findface-tarantool-server/
sudo cp -r /var/lib/findface-security/uploads/* /opt/findface-multi/data/findface-multi-legacy/uploads/
sudo cp -r /var/lib/ffupload/uploads/* /opt/findface-multi/data/findface-upload/uploads/
sudo chmod 777 -R /opt/findface-multi/data/findface-upload/uploads/
sudo chown www-data:www-data -R /opt/findface-multi/data/findface-upload/uploads/*

Instead, the above folders can be directly mounted into the relevant docker containers.

On the host system, stop the ntls service that has been started in step #16.
```
sudo systemctl stop findface-ntls.service
```
Restart the containers.
```
sudo docker-compose restart
```

The update has been completed, but the new version includes new neural network models, so it is also necessary to migrate feature vectors to a different neural network model, or you can use old neural network models by moving them from the /usr/share/findface-data/models/ directory to the /opt/findface-multi/models/ directory, specifying them in the /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml file.

Note that object detection models in FindFace Multi 1.2 are stored in separate directories, i.e., face detection models are stored in the /usr/share/findface-data/models/facedet/ directory, car and body detection models are stored in the /usr/share/findface-data/models/cadet/ and /usr/share/findface-data/models/pedet/ directories respectively. In FindFace Multi 2.1 all object detection models can be found in the /opt/findface-multi/models/detector/ directory. When moving old neural network models from the /usr/share/findface-data/models/ directory to the /opt/findface-multi/models/ directory, make sure to place all object detection models (facedet, cadet, pedet) to the /opt/findface-multi/models/detector/ directory.

Important

We highly recommend disabling the Ubuntu automatic update to preserve the FindFace Multi compatibility with the installation environment. In this case, you will be able to update your OS manually, fully controlling which packages to update.

To disable the Ubuntu automatic update, execute the following commands:

sudo apt-get remove unattended-upgrades
sudo systemctl stop apt-daily.timer
sudo systemctl disable apt-daily.timer
sudo systemctl disable apt-daily.service
sudo systemctl daemon-reload

Update FindFace Multi 2.0 / 2.0.1 to FindFace Multi 2.1 

No matter whether you are updating from FindFace Multi 2.0 or 2.0.1 to FindFace Multi 2.1, the update process will be the same. Do the following:

In a user home directory, create a folder for FindFace Multi 2.0.1 backup data.
```
mkdir ~/201/
```

Back up FindFace Multi configuration files and the docker-compose.yaml file.

sudo tar -cvzf ~/201/configs.tar.gz -C /opt/findface-multi/ configs
sudo cp /opt/findface-multi/docker-compose.yaml /home/ubuntu/201/

Back up PostgreSQL data.

sudo docker-compose cp postgresql:/bitnami/postgresql /home/ubuntu/201/pg_bkp

Back up Tarantool data.

sudo docker exec -it findface-multi-findface-sf-api-1 bash -c "mkdir ffmulti_dump; cd ffmulti_dump && /storage-api-dump -config /etc/findface-sf-api.ini"
sudo docker cp findface-multi-findface-sf-api-1:/ffmulti_dump /home/ubuntu/201/

List content of the /home/ubuntu/201/ folder. It will look like this.

ls ~/201/

configs.tar.gz  docker-compose.yaml  ffmulti_dump  pg_bkp

Stop all FindFace Multi containers from the /opt/findface-multi directory.
```
cd /opt/findface-multi

sudo docker-compose down
```

Remove the /opt/findface-multi/data/findface-tarantool-server/ and /opt/findface-multi/data/postgresql/ folders.

sudo rm -r /opt/findface-multi/data/findface-tarantool-server/

sudo rm -r /opt/findface-multi/data/postgresql/

Install the FindFace Multi 2.1 instance into the /opt/findface-multi directory. Don’t forget to prepare a server first:

See:

Restore Tarantool data from the backup.

Copy /home/ubuntu/201/ffmulti_dump/ to the findface-multi-findface-sf-api-1 container.

sudo docker cp  /home/ubuntu/201/ffmulti_dump/ findface-multi-findface-sf-api-1:/

Restore Tarantool data.

sudo docker exec -it findface-multi-findface-sf-api-1 bash -c 'cd ffmulti_dump && for x in *.json; do /storage-api-restore -config /etc/findface-sf-api.ini < "$x"; done;'

In the new configuration files, replace the NTECH USER password with the one, used in FindFace Multi 2.0.1. The old password can be obtained from the configs/postgresql/40-init.sql file in the backup archive configs.tar.gz. The NTECH USER password should be replaced in the following configuration files:
- findface-multi-legacy.py
- findface-multi-line-crossing-analytics.yaml
- findface-multi-identity-provider.py
- findface-multi-audit.py
- pgbouncer -> userlist.txt
- postgresql -> 40-init.sql
- findface-counter.yaml
In the new configuration file /opt/findface-multi/configs/findface-multi-legacy/findface-multi-legacy.py, replace the SECRET_KEY value in the GENERAL SETTINGS section and 'VIDEO_DETECTOR_TOKEN' value in the FINDFACE SECURITY SETTINGS section with the ones, used in FindFace Multi 2.0.1. The old parameter values can be obtained from the configs/findface-multi-legacy/findface-multi-legacy.py file in the backup archive configs.tar.gz.
Compare previous configuration files against the new ones. Move all custom parameters from the previous version to the new one. Compare configuration files for the services findface-ntls, findface-extract-api, findface-sf-api, etc. You may need to apply changes to the docker-compose.yaml file if you previously configured it to bring or exclude services or made any other changes.

Important

Carefully check your previous configs/findface-sf-api/findface-sf-api.yaml configuration file in the configs.tar.gz backup archive against the new one /opt/findface-multi/configs/findface-sf-api/findface-sf-api.yaml. If your shard structure differs from the default structure (different number of shards, address is other than local 127.0.0.1, etc.), specified in the /opt/findface-multi/configs/findface-sf-api/findface-sf-api.yaml configuration file, we recommend contacting our support team (support@ntechlab.com) for advice.
Important

Follow these rules to transfer parameters from the old configuration file to the new one:
- If there is a new neural network model in the new configuration file, replace it with the previous one (considering that the previous model is still included in FindFace Multi 2.1), and if the previous model is missing in FindFace Multi 2.1, then do not change anything. In this case, you will have to do migration to a different neural network model.
- If a parameter had an empty value in the old configuration file, but has a certain value in the new configuration file, delete its value in the new configuration file.
- Keep as is those parameters that were not included in the old configuration file, but are present in the new configuration file.

There are fresh neural network models for body recognition and vehicle recognition in FindFace Multi 2.1.

In the /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml file, replace the pedrec.clio model with the pedrec.durga model for the extractor body_emben.

sudo vi /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml

CPU

extractors:
  ...
  models:
    ...
    body_emben: pedrec/pedrec.durga.cpu.fnk
    ...

GPU

extractors:
  ...
  models:
    ...
    body_emben: pedrec/pedrec.durga.gpu.fnk
    ...

Also, in the same configuration file, replace the alonso model with the bottas model for the extractor car_emben.

sudo vi /opt/findface-multi/configs/findface-extraction-api/findface-extraction-api.yaml

CPU

extractors:
  ...
  models:
    ...
    car_emben: carrec/bottas.cpu.fnk
    ...

GPU

extractors:
  ...
  models:
    ...
    car_emben: carrec/bottas.gpu.fnk
    ...

Remove the findface-multi-postgresql-1 container.

sudo docker rm -f findface-multi-postgresql-1

Stop all FindFace Multi containers from the /opt/findface-multi directory.
```
cd /opt/findface-multi

sudo docker-compose down
```
Copy data from the /home/ubuntu/201/pg_bkp/data/ directory to the /opt/findface-multi/data/postgresql directory.
```
sudo cp -r /home/ubuntu/201/pg_bkp/data/ /opt/findface-multi/data/postgresql
```

Define roles.

sudo chown -R support:support data/postgresql/data

Start all FindFace Multi containers from the /opt/findface-multi directory.
```
cd /opt/findface-multi

sudo docker-compose up -d
```
