Nvidia Modulus and NumPy 1.21.5 incompatibility issue

[epochstamp]

Hi,

During installation, I noticed that the Modulus library does not support any version of NumPy that falls below 1.22.4, yet LIPS requires a NumPy version of 1.21.5

A quick fix is to simply change, in the setup file, the required version from NumPy to 1.22.4 (haven't tested the whole LIPS repository but it seems to work for basic training/evaluation + haven't tested for newer versions of NumPy).

I suggest to switch to NumPy 1.22.4 (upon thorough testing) in the requirements and in the official setup file to ensure the compatibility with Modulus.
