Description

Any attempt to run spleeter on a Github Actions runner results in a 404 GET failure at the step for downloading the pre-trained model from spleeter's URL (https://github.com/deezer/spleeter/releases).

Instead, the job attempts to fetch the pretrained model from the current Github repo's URL (https://github.com/my-org/myrepo/releases) , which is non-existent, and returns a 404 Not Found.

Root Cause

Spleeter uses the [following environment variables(https://github.com/deezer/spleeter/blob/master/spleeter/model/provider/github.py#L88-L90) for building the fetch URL for its pre-trained, published models:

• GITHUB_HOST
• GITHUB_REPOSITORY
• GITHUB_RELEASE

Unfortunately, GITHUB_REPOSITORY is a reserved environment variable in the context of Github Actions, and gets picked up at runtime, resulting in an incorrect destination model URL.

Solution Options

One alternative is to explicitly set GITHUB_REPOSITORY at the time of invocation of spleeter.

$ GITHUB_REPOSITORY="deezer/spleeter" poetry run python lib/stem_split.py

However, this could introduce undesired side-effects in the Github Action by overriding what should be the original expected value that's set by the environment by default.

A more appropriate solution would be to make the internal usage of spleeter-specific Github environment variables even more distinct, than the current, generic, conflicting names.
