hi, let me try to reproduce this bug, ideally we should have pytest for this library, pytest is only needed when running testing.

Hi @MEllis-github , I think decorator will be installed as a dependency of fabric. May I know which version of fabric you have installed?

As for the pytest error report, you can just move this line in the colossalai.testing.pytest_wrapper.py.

import os
- import pytest

def run_on_environment_flag(name: str):
    ...

+   import pytest
    assert isinstance(name, str)

I will check.
In the meantime, to be clear, this was triggered by running colossalai -i check in/using docker.io/hpcaitech/colossalai:0.3.0.
The only additional dependencies installed were the following for autoparallel

RUN pip install --no-cache-dir "transformers>=4.23.1" "pulp>=2.7.0" && \
    conda install -y -c conda-forge coin-or-cbc && \
...
