A bug when installing new environment in Conda
(base) atcold@AlfMAC3 ~ $ which python /usr/local/bin/python # system python (base) atcold@AlfMAC3 ~ $ conda activate PPUU (PPUU) atcold@AlfMAC3 ~ $ which python /usr/local/bin/python # still system python! Workaround: run conda deactivate.
Launching new shell
(base) atcold@AlfMAC3 ~ $ conda deactivate atcold@AlfMAC3 ~ $ conda activate PPUU (PPUU) atcold@AlfMAC3 ~ $ which python /Users/atcold/opt/miniconda3/envs/PPUU/bin/python # virtual environment python (PPUU) atcold@AlfMAC3 ~ Seems like (base) needs to be deactivated first.
