Problems with memory mapped files and vectors.most_similar()

Hello. I am on windows using python 3.6

There seems to be a problem with creating the magmap files for using the vectors.most_similar() method. Error:

  File "\pymagnitude\__init__.py", line 1074, in get_vectors_mmap
    os.rename(path_to_mmap_temp, self.path_to_mmap)

PermissionError: [WinError 32] The process cannot access the file because it is in use by another process \\AppDataTemp\\82ce74f40baf842d23c45b0e90688b9f.magmmap.tmp' -> '\AppData\\Local\\Temp\\82ce74f40baf842d23c45b0e90688b9f.magmmap'

I looked into the code and it seems you are creating and filling these files in the background. It works fine for the vectors.most_similar_approx() method. The memmap file for approx seems to be created just fine.

The problem persists even when i use blocking=True when constructing the magnitude object. Then i can’t even use the approx method. It just hangs while initializing the object.

Thank you for your time.

Your welcome and thanks for the help in making it Windows compatible! I added your handle as a Developer on the GitLab repository. If you come across any other issues, feel free to submit a pull request / merge request to get it merged into master and deployed to PyPI.

Would love to see what you working on / end up doing with Magnitude in your master’s thesis, e-mail us at [e-mail] if you can share it.
