AttributeError: module 'numpy' has no attribute 'int'.
`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:
    https://numpy.org/devdocs/release/1.20.0-notes.html#deprecations

Using numpy 1.24.3, arc 3.3.0

Also np.complex, etc...

I have the same problem when using ARC (3.2.8) with new versions of numpy. The solution is ostensibly simple: replace the deprecated numpy types with their native Python equivalents, but perhaps some higher-level coordination is required here since I don't know to what extent this problem permeates the ARC code.

Should be resolved in ARC v3.4.0
