Hi I tried loading a custom parsing model through spacy but I get a FileNotFoundError:/vocab/lexemes.bin.  
I even tried forcefully linking with the 'en' model using python -m spacy link en\_core\_web\_md en --force as given in the link [https://github.com/explosion/spaCy/issues/2406](https://github.com/explosion/spaCy/issues/2406), But nothing really seemed to work.  
The spacy version I am using is 2.3.4.  
Please help me out.  
Thanks

What does `spacy. __version__ ` show in your environment?

From the error message it looks like you're trying to load a v2.3 model with spacy v2.2 (or earlier).

Hi, the spacy. **version** = 2.3.4 in my environment. I have also verified that all installed models are compatible with the _spaCy_ version I have

I'm very sure that spacy v2.3.4 won't try to open a file called `vocab/lexemes.bin`. Just to double-check can you add a cell to your notebook that runs `!python -m spacy info`?

Another possibility: if you upgraded spacy in this venv, it's also possible that some older files didn't get cleaned up correctly by `pip`, so if you're still stuck, try creating a brand new virtual environment and installing spacy again to test to make sure it's not something with the virtual environment.
