I got this error:

```auto

...

Traceback (most recent call last):

During handling of the above exception, another exception occurred:

```

why? seems odd. Thought this fixed it it seems:

```auto
pip install --upgrade pip
pip install chardet # might be needed if wandb acts weird

```

idk why this is needed but this seems to work:

```auto
pip install --upgrade pip
pip install wandb --upgrade
if ! pip show chardet > /dev/null; then
    pip install chardet
fi
if ! pip show cchardet > /dev/null; then
    pip install cchardet
fi
python -c "import uutils; uutils.torch_uu.gpu_test()"

```

shouldn’t be happening in the first place…

Hello @brando !

This looks to be an issue with importing the `requests` package (which is in turn importing `chardet` incorrectly). As seen by the following lines:

```auto
File "/lfs/ampere1/0/brando9/miniconda/envs/data_quality/lib/python3.10/site-packages/wandb/util.py", line 49, in <module>
    import requests
File "/lfs/ampere1/0/brando9/miniconda/envs/data_quality/lib/python3.10/site-packages/requests/ __init__.py", line 45, in <module>
    from .exceptions import RequestsDependencyWarning
  File "/lfs/ampere1/0/brando9/miniconda/envs/data_quality/lib/python3.10/site-packages/requests/exceptions.py", line 9, in <module>
    from .compat import JSONDecodeError as CompatJSONDecodeError
  File "/lfs/ampere1/0/brando9/miniconda/envs/data_quality/lib/python3.10/site-packages/requests/compat.py", line 13, in <module>
    import charset_normalizer as chardet

```

I did look into the Stack Overflow discussion that you provided and it seems like the issue seems to be a conflict between `pip` and `conda` (which you were able to fix gladly).
