问题 How can I annotate the yield type of a contextmanager in PyCharm so that it properly guesses the type of the value used in the with clauses - just as it guesses that the f created in with open(...) as f is a file?

问题 I have a ROS application which has a work space with a setup.bash file and another python script with its own virtual environment. So far this is what I do in my terminal: 1_ pipenv shell (to activate my python virtual environment). 2_ source ../ros_workspace/devel/setup.bash 3_ python some_python_script.py This code works as I expect. However, I want to do the same and run this script in pycharm, where my virtual environment is already activated. But how do I source the setup bash

How should this warning

问题 I would like to create project in PyCharm by open directory. I use https://github.com/metachris/tornado-boilerplate as a root of the project. I encountered that files are shown in red color in project window. It's really annoying thing. I found this https://www.jetbrains.com/idea/help/file-status-highlights.html.
