ERROR: could not find a version that satisfies the requirement torch==1.9.1+cu111

Hi I am having a problem when I type

Pip install -requirement.txt

ERROR: could not find a version that satisfies the requirement torch==1.9.1+cu111(from versions 0.1.2, 0.1.2post1, 0.1.2post2
ERROR: No matching distribution found for torch==1.9.1+cu111

I use python 3.10

It seems your pip environment can only find old versions, so you might need to update it.
