Conda env is activated using source activate env_name.
How can I activate the environment in pycharm ?
environment.ymlPycharm can create a new conda environment indeed. Unfortunately, until this issue is fixed, it won't offer environment.yml support, which means it won't install the dependencies declared there.
When working on a project based on such a file, you need to create / update the dedicated env manually on your machine:
conda env create -n
Then remember to update each time environment.yml changes (from you or upstream).
conda env update -n
Not ideal
