Rename and cleanup conda Python environment

Rename Python conda environment “old” to “new” by copying the environment and deleting the original environment:

conda create --name new --clone old

conda remove --name old --all

Each Miniconda/Anaconda environment consumes disk space. One may wish to delete old, unused conda environments to free disk space. Conda environment disk size can be checked by listing all environment paths

conda env list

This will show entries like:

py37 ~/miniconda3/envs/py37

Print the disk size of a conda environment:

• Linux / macOS: du -sh ~/miniconda3/envs/py37
• Windows: dir miniconda3/envs/py37
