Poetry - how to install package with transitive dependency with markers

[MarkoMilos]

Hey everyone,

I'm currently working on a Python project where I'm using Poetry for dependency management and I'm having an issue with installing OpenAI Whisper on a green field project.

STEPS

1. Create an empty poetry project
   poetry new poetry-demo

2. Navigate to the project directory
   cd poetry-demo

3. Start a shell (creates a virtual env)
   poetry shell

4. Install openai-whisper package
   poetry add openai-whisper

This fails with

  - Installing triton (2.2.0): Failed
  RuntimeError
  Unable to find installation candidates for triton (2.2.0)

As can be seen in official GitHub repository for OpenAI whisper the repo has the following dependencies

numba
numpy
torch
tqdm
more-itertools
tiktoken
triton>=2.0.0,<3;platform_machine=="x86_64" and sys_platform=="linux" or sys_platform=="linux2"

So I'm trying to install openai-whisper package that has a transitive dependency to the triton package with markers (for linux platform). But I'm running this on Mac M3 (Apple Silicon). The triton package is specified with environment markers for x86_64 Linux machines, making it irrelevant to my setup.

Is there any way to instruct poetry not to install that transitive dependency?

Has anyone here faced a similar situation or have suggestions on how to handle this? Any advice on how to configure my pyproject.toml or if there's a feature in Poetry that I'm missing would be greatly appreciated. I'm hoping to find a clean, maintainable solution that allows me to continue using this third-party package without manual hacks.

Thanks in advance for your insights and help!

Turns out that the problem was how openai-whisper packaged their distribution.

The relevant pull request is here: openai/whisper#1887

The workaround is to install it directly from the repo for now since the merged change is still not available via pypi.

poetry add git+https://github.com/openai/whisper.git
