Reflect the virtual environment created by virtualenv or conda in the IntelliJ IDEA (PyCharm) project (memo)

Problem: I can't see the packages installed in the virtual environment

Solution

Open Project Structure with command +; and select Python SDK> Add Local from+in the upper left.

Set the bin / python path of the virtual environment. In my environment / Users / user_name / anaconda / envs / machine_learning_env / bin / python

After adding, you will be able to resolve the path with apply.

If it doesn't work, it's quick (maybe) to delete the entire .idea / directory and recreate the project.
