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

Thanks for pointing this out! In the repository it was fixed for quite some time but I had missed to also push the new version to PyPI. Now, you can upgrade with pip install transitleastsquares --upgrade to version 1.32 and the error should be gone.

Thanks! I can confirm I have upgraded the package via pip and it works now.
