When trying to run Falcon on Windows Powershell (x64 run as admin) with Python 3.9, I get the following error:

falcon : Traceback (most recent call last):

During handling of the above exception, another exception occurred:

Falcon was installed via pip.

Apologies, I forgot to include in the README that only Linux and OSX are supported. falcon uses the Faiss library for fast nearest neighbor searching, which unfortunately does not support Windows.

I have made a note of this in the README now.
