numpy recommended version not compatible

[etiur]

While running iLigand it give me this error:

AttributeError: module 'numpy' has no attribute 'float'.
np.float was a deprecated alias for the builtin float. To avoid this error in existing code, use float by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.float64 here.
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

This error is due to:

• line 107 of connectvity.py
• line 20, 33, 65 of estate.py

However the recommended numpy version is numpy (>=1.21.4)
