 ImportError: cannot import name 'int' from 'numpy'

Can't load PyDSTool with numpy version 1.26.0 

I think this is because of this [deprecation](https://numpy.org/doc/stable/release/1.20.0-notes.html#using-the-aliases-of-builtin-types-like-np-int-is-deprecated), which took effect for version 1.20.0
