issue in pygrid with np.int and np.warnings

[andreldeod]

Hey I ran into an issue using the pygrid module in this notebook.

It uses np.int and np.warnings, which are deprecated or don't exist.

• np.int should be replaced with np.int_

• np.warnings should be replaced with warnings

I tried modifying pygrid with the modifications mentioned and the code worked for me.

Here's some of my error messages:

np.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`
