Troubleshooting Steps

To resolve the ‘No module named ‘finta” error, follow these troubleshooting steps:

If you are getting below error.

then , you want to modify the Docker Compose configuration to build a custom Docker image for Freqtrade with additional dependencies. Here’s the step-by-step process:

1. Modify docker-compose.yml:
   Open your docker-compose.yml file and find the service definition for Freqtrade. Change the image line to point to your custom image name, and uncomment the build line:

     # image: freqtradeorg/freqtrade:stable  # Comment out or remove this line
       image: freqtradeorg_custom/freqtrade_custom:custom  # Your custom image name
  
 services:
     freqtrade:
       build:
         context: .
         dockerfile: Dockerfile.custom  # Specify the custom Dockerfile
  

This tells Docker Compose to build the Freqtrade service using the Dockerfile.custom and tag it with your custom image name.

2. Create Dockerfile.custom:
   Create a file named Dockerfile.custom in your project directory with the following content:

   FROM freqtradeorg/freqtrade:develop

   # Switch user to root if you must install something from apt
   # Don't forget to switch the user back below!
   # USER root

   # Install additional dependencies
   RUN pip install --user finta

   # Switch back to user (only if you required root above)
   # USER ftuser

In this Dockerfile, you’re extending the base Freqtrade image and installing the ‘finta’ module using pip.

3. Build and Run Docker Compose:
   Now, you can build and run your Docker Compose setup as usual.

    docker compose build --pull

Docker Compose will use the Dockerfile.custom to build the Freqtrade image with the ‘finta’ module included and tag it with your custom image name.

With these steps, you’ve successfully modified your Docker Compose configuration to build a custom Freqtrade image with the ‘finta’ module included. This approach allows you to extend the functionality of your Freqtrade setup while maintaining the benefits of containerization provided by Docker.

Alternative Solutions

If the above steps do not resolve the issue, consider these alternative solutions:

Using Pip to Install Finta

You can directly install Finta using Pip with the following command:

pip install finta

Manually Installing Finta

Alternatively, you can manually install Finta by downloading the package from the Python Package Index (PyPI) and installing it using Pip.
