Could not find a version that satisfies the requirement torch>=1.0.0?
I finally managed to solve this problem thanks to John Red' comment and serg06 answer. Here's what I've done :

Install Python 3.7.9 and not newer.
BUT make sure to install 64bits python

Every other combination failed for me.
Could not find a version that satisfies the requirement torch>=1.0.0 
No matching distribution found for torch>=1.0.0 (from stanfordnlp)
