I tried everything here twice and even more  I finally solved it doing something I hadn t seen anywhere online   If you go to Settings gt Editor gt File Types there is an  Ignore Files and folders  line at the bottom   In my case  I was ignoring  venv   which is what I always name my virtual environments   So I removed venv  from the list of directories to ignore and VOILA    I was FINALLY able to fix this problem   Literally all of my import problems were fixed for the project  BTW  I had installed each and every package using PyCharm  and not through a terminal   Meaning  by going to Settings gt Interpreter      I had invalidated cache  changed  Source Root   restarted PyCharm  refreshed my interpreters paths  changed interpreters  deleted my venv     I tried everything   This finally worked  Obviously there are multiple problems going on here with different people  so this may not work for you  but it s definitely worth a shot if nothing else has worked  and easy to reverse if it doesn t

Although all the answers are really helpful  there s one tiny piece of information that should be explained explicitly    Essentially  a project with multiple hierarchical directories work as a package with some attributes  To import custom local created Classes  we need to navigate to the directory containing  py file and create an   init   py  empty  file there    Why this helps is because this file is required to make Python treat the directory as containing packages  Cheers

Generally  this is a missing package problem  just place the caret at the unresolved reference and press Alt Enter to reveal the options  then you should know how to solve it

In my case the problem was I was using Virtual environment which didn t have access to global site-packages  Thus  the interpreter was not aware of the newly installed packages   To resolve the issue  just edit or recreate your virtual interpreter and tick the Inherit global site-packages option

After following the accepted answer  doing the following solved it for me   File   Settings   Project  lt your directory project gt    Project Dependencies  Chose the directory project where your file that has unresolved imports resides and check the box to tell Pycharm that that project depends on your other project   My folder hierarcy is slightly different from the one in the question  Mine is like this   -- MyDirectory                -- simulate py    -- src                -- networkAlgorithm py                --       Telling Pycharm that src depends on MyDirectory solved the issue for me

Manually adding it as you have done is indeed one way of doing this  but there is a simpler method  and that is by simply telling pycharm that you want to add the src folder as a source root  and then adding the sources root to your python path  This way  you don t have to hard code things into your interpreter s settings   Add src as a source content root                                                            Then make sure to add add sources to your PYTHONPATH under  Preferences   Build  Execution  Deployment   Console   Python Console      Now imports will be resolved                                               This way  you can add whatever you want as a source root  and things will simply work  If you unmarked it as a source root however  you will get an error                                                                      After all this don t forget to restart  In PyCharm menu select  File -- gt  Invalidate Caches   Restart

For my case   Directory0      -- Directory1             -- file1 py        -- Directory2             -- file2 py    Into file1  I have   from Directory2 import file2  which trows an  quot unresolved reference Directory2 quot   I resolved it by   marking the parent directory Directory0 as  quot Source Root quot  like said above  AND  putting my cursor on another line on the file where I had the error so that it takes my modification into account  It is silly but if I don t do the second action  the error still appears and can make you think that you didn t resolve the issue by marking the parent directory as Source Root
