Alert for environment mismatch

[skoudoro]

@arokem I think the issue is that even though I was running from brand new environment, the shim was using trx from an older environment:

(pydi) trx-python % which -a trx
/Users/chris/.pyenv/shims/trx

AI suggested I do a series of steps, and my experience with Python is insufficient to know the crucial one, but I think it was something like this:

"$(pyenv which python)" -m pip uninstall -y trx-python
pyenv rehash 

After which it did succeed:

(pydi) trx-python % trx convert ~/simple.trk ./output.trx 
/Users/chris/pydi/lib/python3.13/site-packages/trx/viz.py:9: UserWarning: You do not have FURY installed. Some visualization functions might not work for you. Please install or upgrade FURY using pip install -U fury. For detailed installation instructions visit: https://fury.gl/
  from dipy.viz import actor, colormap, window
Successfully converted /Users/chris/simple.trk to output.trx
(pydi) trx-python % ls *.trx
output.trx

The good news is that it did work, but the problem was not intuitive. Is there a way to avoid these issues?
