Failing to build with docker-compose up (steps to make it working)

[Pablohn26]

When I run docker-compose up I get the following error when running the container:

Step 15/15 : CMD ["venv/bin/python3", "server.py", "-c", "services.json", "-p", "80"]

The error was here:

opus-mt_1  | FileNotFoundError: [Errno 2] No such file or directory: './models/en-es/source.bpe'
opus-mt_1  | [2023-01-26 16:24:07] Error: File './models/en-es/decoder.yml' does not exist

You have to download the model here and uncompress the zip file in folder models/en-es

Then, trying again, you hit the following error:

Error: File './models/en-fi/decoder.yml' does not exist

That is because default configuration includes en-es and en-fi. To fix that (removing en-fi, you have to delete here in the configuration file and here in the Makefile, removing en-fi and leaving the line as following:

tornado-models: models/en-es

Then run docker-compose up --build and it will be working.
