It seems that the deprecation of 'np.int' in recent versions of numpy has caused multiple functions in radmc3dPy to be nonfunctional.
I have attached an example error log below, showing what happens when the readMol() function is used. However, it is likely that this issue affects multiple other parts of the code as well.
The error log includes some recommendations about how to fix the error, and a numpy webpage detailing the change.
This is using numpy version 1.24.3.
Using an older numpy version should be a valid workaround for now, but some packages I work with are starting to require more-recent numpy versions.
Interestingly, despite numpy claiming the deprecation happened in numpy version 1.20, I have observed that this code does work in versions as recent as 1.21.2.

`np.int` was a deprecated alias for the builtin `int`. To avoid this error in existing code, use `int` by itself. Doing this will not modify any behavior and is safe. When replacing `np.int`, you may wish to use e.g. `np.int64` or `np.int32` to specify the precision. If you wish to review your current use, check the release note link for additional information.
The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:
