Can't install scispacy on Windows - nmslib build fails

See original GitHub issue
On Win 10, my pip install scispacy tries to build the wheel for nmslib (and fails), then tries to fall back to run setup.py - and fails again. I have Visual Studio Build Tools 2019 build tools installed, so there SHOULD be valid compiler/headers on the system… but something’s not matching. BTW I had to downgrade to numpy 1.19.3 due to some error message about bugs in newer version. Python version: 3.9.0
stderr from pip install scispacy :

Sorry - I know this is closed. I ran into a similar issue but it’s all fixed now and I wanted to share my experience incase anybody runs into the same issue.
Currently, nmslib only supports python < 3.9. I’ve tried 3.9, 3.91, and 3.85. Only 3.85 worked. Here’s an image showing that their latest python binary is 3.8:
Once I had Python 3.85 64-bit (nmslib does not support 32-bit - atleast on windows) - nmslib installed fine. I then installed scispacy and it seems to be working right.

@alexbellin I can confirm that this is the case. In my case I used 3.8.7. I am not really sure why installing 3.9.1 creates a syntax error in the code but it is what it is.
