Hi Nunes
I have been following your video trying to set up Facsvatar with Blender 2.80 and 2.95b on Windows 10. I have got the 3 Anaconda windows working as in the video but when I enter the first two lines from facsvatar_zeromq.py in the Blender python console, Blender does not freeze but the script runs to error as below and I am at a loss as to what is wrong. Both environments have python (3.7 and 3.5 respectively) and pyzmq.
I’m not too tech savvy – this is the first time I’ve used Anaconda and environments so I would appreciate any simple guidance you can give.
That said what a marvelous project you have.

script = "C:\Users\mojay\FACSvatar-master (7)\blender\facsvatar_zeromq.py"
exec(compile(open(script).read(), script, 'exec'))

Traceback (most recent call last):
