Pycharm shows "Unresolved reference" all of a sudden

Question

I have no idea what I could have done but Pycharm now decides to claim that it doesn't know things like TaggedDocument or Doc2Vec although it worked an hour ago.

This is my project structure:

I can't remember doing anything that could have cause this so please tell me how I could fix this.

The thing I don't get it that under "External Libraries in the Project Explorer I can actually see that gensim.models.doc2vec is actually present. So why does PyCharm still complain here?

Update

I noticed the following: In the package gensim.models I see that the file doc2vec.py is not labeled as a Python file! Please note on the right side that there is also no syntax highlighting! The strange thing is that all other files in that directory are actually recognized correctly!

These are the file permissions under /usr/local/lib/python2.7/dist-packages/gensim/models

and here is the entire content of my doc2vec.py.

are you using the correct python interpreter maybe you are using 2.7.x and not 3.x or the other way around? — Donat Pants, Apr 24 '16 at 15:16
Under `Settings` of my project it says I am using `/user/bin/python2.7`. — Stefan Falk, Apr 24 '16 at 15:20
shouldn't you be importing from wordvectors.models.doc2vec and not gensim.models.doc2vec? or even just from models.doc2vec — Donat Pants, Apr 24 '16 at 15:21
If I **Ctrl + L-Mouse** `doc2vec` in `gensim.modls.dov2vec` it actually opens the file but it doesn't seem to interpret it as Python file since there is no syntax highlighting. — Stefan Falk, Apr 24 '16 at 15:22
well to know what is wrong i would have to see the models pack and the source of Doc2Vec to see if it really has the TaggedDocument, Doc2Vec classes/functions in it — Donat Pants, Apr 24 '16 at 15:24
@DonatPants No, in `models/` there is just a large CSV file. I want to use `gensim`. Like mentioned above this worked just fine an hour ago but all of a sudden it allies with all the other **** that is not working at the moment to make this an even greater hell than what it already is .. — Stefan Falk, Apr 24 '16 at 15:24
IMHO adding the project's `.idea` dir to the version control system is a good way to figure out what causes unexpected PyCharm behaviour changes and often even restore the expected behaviour :) — Dan Cornilescu, Apr 24 '16 at 19:27

Do you have gensim in settings -> Your project -> Project Interpreter Package list? — valex, May 16 '16 at 14:21
Have you tried to uninstall the `gensim` package and install again? Thanks. — alecxe, May 17 '16 at 02:32
@alecxe Yes, I even switched between the community and the education version. It's the same in both. The script is running but PyCharm keeps telling me that it does not find those classes even though it finds the files .. — Stefan Falk, May 17 '16 at 10:33
Did you make sure that every directory that is a module have the \_\_init\_\_.py file? — Gabriel Muj, May 20 '16 at 07:33
Try [cleaning the system caches](https://www.jetbrains.com/help/pycharm/2016.1/cleaning-system-cache.html): `PyCharm > File > Invalidate Caches / Restart ... > [Invalidate and Restart]` — Darius, May 20 '16 at 12:36
@DariusM. Unfortunately this did not help either.. I am not getting this.. especially because the module is getting indexed and I can actually jump into the file .. — Stefan Falk, May 20 '16 at 12:53
@PadraicCunningham Only the red underlines and only for the gensim packages it seems .. — Stefan Falk, May 22 '16 at 14:17
To me, this happens from time to time. Either invalidation of cache like above, or a restart will usually fix the problem. Otherwise, try to reinstall python. You should really look into running virtual env, since it's easier to rebuild everything if something fails. — OakNinja, May 22 '16 at 21:26
@DanCornilescu I updated my question - I found that `doc2vec.py` is for some reason not detected or interpreted as Python file O_o — Stefan Falk, May 23 '16 at 06:52
@displayname the only thing as I see it that could be the problem is that there is no `taggedDocument` or `Doc2Vec` inside `gensim.models.doc2vec`. would you mind showing the code inside that file? — Donat Pants, May 23 '16 at 10:28

Please check that you didn't accidently removed parts of the code from doc2vec.py file because it's strange that pycharm can give a direct path for this file but can't read it. Another thing that can happen but will be totally weird is things about permissions, maybe you've changed permissions in this folder and now pycharm doesn't have the permissions to read this file?

I checked.. the class `Doc2Vec` is present in my `gensim.models.doc2vec`. I didn't modify any of these files. I am not getting this. No other library has this problem. Whether if it's `numpy`, `random` or `os` .. – Stefan Falk May 23 '16 at 06:47
Could you please upload the content of gensim.models.doc2vec? And again, I'm guessing you're on based unix OS (interpreter /usr/bin/python) so please do compare file permissions against other .py files in the same folder. – Rotem Vil May 23 '16 at 07:58
Another thing, please open settings (ctrl+alt+s), type in search bar for "file types", check that in the bottom text box there isn't a regex that matches your file and just for some weird case - look on python files to see if .py is registered as a registered pattern. – Rotem Vil May 23 '16 at 08:07
Tried all that. I checked file permissions (see updated question) and I uploaded the content of my doc2vec.py - I just don't get this. doc2vec.py is still the only file that does not get syntax highlighted. It's displayed as a textfile .. – Stefan Falk May 23 '16 at 11:06
Great thank you for all the info. My last guess is to try to change the name of the file by using refactor (Shift+F6) to doc2vec.txt and then again change the name of the file to doc2vec.py - please update me :) thanks! – Rotem Vil May 23 '16 at 11:10
Omg that was it! It somehow got under "Text" in "File Types" - I have no idea how but it seems I somehow messed up my config somewhere between the educational version and the community version! Thank you very much for your help - such a stupid mistake but at least it works finally! – Stefan Falk May 23 '16 at 11:12

Last chance, try by enabling the following (source):

I cannot test this right now but I will try this tomorrow! – Stefan Falk May 22 '16 at 14:17
