I just installed the latest version of PyCharm (4.5).
Now I am experiencing unresolved reference errors. On the top of my code I have:
from datetime import datetime
OS is Ubuntu 15.04. Already did the Invalidate Cache/Restart several times. No difference. The Project interpreter of my project is set to Python 2.7.6. Already reloaded the Interperter Paths.
Code works fine, it's just the IDE that produces an annoying error and no more autocomplete.
