Train a model locally

This is a step by step guide on how to train a model from the Marketplace with your own dataset.

1. Get Docker

The first step is having Docker installed. To have an up-to-date installation please follow the official Docker installation guide.

2. Search for a model in the marketplace

The first step is to choose a model from the DEEP Open Catalog marketplace. For educational purposes we are going to use a general model to identify images. This will allow us to see the general workflow.

3. Get the model

Once we have chosen the model at the DEEP Open Catalog marketplace we will find that it has an associated docker container in DockerHub. For example, in the example we are running here, the container would be deephdc/deep-oc-image-classification-tf. This means that to pull the docker image and run it you should:

$ docker pull deephdc/deep-oc-image-classification-tf

4. Export rclone.conf file

When running the container you should export the rclone.conf file so that it can be reached from within the docker. You can see an example on how to do this here

$ docker run -ti -v  -p 5000:5000 -p 6006:6006 -v  host_path_to_rclone.conf:/root/.config/rclone/rclone.conf <your-docker-image>

You can see this last step explained more in detail here.

We are using the port 5000 to deploy the API and the port 6006 to monitor the training (for example using Tensorboard).

5. Upload your data to storage resources

To run locally you have two options:

1. Have your data stored locally

You should make sure that you export inside of the container all the folders you need for the training

$ docker run -ti -v  -p 5000:5000 -p 6006:6006 -v path_to_local_folder:path_to_docker_folder -v host_path_to_rclone.conf:/root/.config/rclone/rclone.conf <your-docker-image>

2. Have your data at a remote storage resource

  • Nextcloud

If you have the files you need for the training stored in Nextcloud you need first to login into DEEP-Nextcloud with your DEEP-IAM credentials. Then you have to go to: (1) Settings (top right corner)(2) Security(3) Devices & sessions


Set a name for your application (for this example it will be deepnc) and clik on Create new app password. This will generate <your_nextcloud_username> and <your_nextcloud_password> that you should to include in your rclone.conf file (see more details.).

Now you can create the folders that you need in order to store the inputs needed for the training and to retrieve the output. In order to be able to see these folders locally you should run either on your local host or on the docker container

import subprocess

# from deep-nextcloud into the container
command = (['rclone', 'copy', 'deepnc:/path_to_remote_nextcloud_folder', 'path_to_local_folder'])

results= subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
output, error = result.communicate()
  • Google Drive


  • Dropbox


6. Train the model

Now comes the fun! Go to and look for the train method. Modify the training parameters you wish to change and execute. If some kind of monitorization tool is available for this model you will be able to follow the training progress from

7. Testing the training

Once the training has finished, you can directly test it by clicking on the predict method. There you can either upload the image your want to classify or give a URL to it.
