I just updated Pycharm to the latest version and I\'ve been having trouble with this error message. Basically, I can\'t turn off the error message that says \"Python version
Thanks to @user2235698, I fixed the issue by removing my project interpreter and re-adding it to Pycharm.
Ubuntu did an update which changed my Python 3 version from 3.6 to 3.5, but Pycharm didn't realize it was changed. Updating the interpreter directory from /usr/bin/python3 to /usr/bin/python3.6 fixed things.
Thanks again everyone! Marking this as solved.
