ncNet can't work with python 3.10

[poludmik]

README states that the required python version is 3.6+.
However, when trying to install requirements.txt with on top of python3.10, it won't install.

Errors such as "ERROR: Could not find a version that satisfies the requirement torchtext==0.8 (from versions: 0.1.1, 0.2.0, 0.2.1, 0.2.3, 0.3.1, 0.4.0, 0.5.0, 0.6.0, 0.12.0, 0.13.0, 0.13.1, 0.14.0, 0.14.1, 0.15.1, 0.15.2)
ERROR: No matching distribution found for torchtext==0.8" follow.

pytorch==1.7. in requirements.txt was not supporting e.g. python3.10 at the moment.

Problem was solved by switching to python version 3.7. Consider changing Python3.6+ in README to Python3.6 to 3.7.
