PyCharm unresolved references
- pycharm
This is a known problem with PyCharm. (A couple years for me as of August 2014 - davidism) Going to File > Invalidate Caches > Invalidate and Restart will re-cache the references and should solve the issue until it comes back a few weeks later.
Alternatively, the asker may not have configred an interpreter for the project, so there are no references at all.
