Some important things to note when one tries to use a remote interpreter in PyCharm:

1. If you are using two instances of PyCharm, e.g. on two differenct machines:
   • map the project to a separate folder in the remote disk, the default /tmp/_______ should be fine, but it could be anywhere.
   • map the .pycharm_helper folder to a separate directory too, e.g. for home machine access create a ~/.pycharm_helper_home to map to.
2. If you are using conda environments, do the following to actually get conda working:
   • suppose you are using an environment called my_conda_env, find the location of the python executable, e.g. you can do

     $ conda activate my_conda_env
     $ which python

• For people who sometimes jump from one language/env to another and forget syntax idiosyncrasies: Hyperpolyglot.
