Hi there, I like your script, but I found an error in line 92:

CALL !CONDASCRIPTS!activate base && (

should be

CALL !CONDASCRIPTS!activate %CONDA_ENV% && (

or? Otherwise the set conda environment is not used but always the base environment.

Thanks for sharing this little helper :)

Oh, you are totally right, @pixx1. I updated the version accordingly. Please let me know if anything continues not to work as intended.

This is amazing!
Worked right away!
Thank you for the good code and even better effort 😄

Thank you, this is great
