Please consider using latest/stable numpy and other python packages.

@ArjunChakrawal thank you! We will address this.

@aramyxt can you please update the packages?

Hi @ArjunChakrawal and @maruti-iitm ,

I will do some testing to make sure the latest versions of numpy are compatible with the other dependencies, such as Porespy.
Last time I attempted to run the latest version, running a pore network extraction resulted in a library error. Let me double check if this is still the case. Thanks!
