Compatibility Issue with NumPy 2.x: np.ComplexWarning Not Defined

[J-Christophe]

Hello,

I am experiencing an issue with the deepdish library when using it with NumPy 2.1.0. Specifically, I cannot import deepdish due to the following error:

AttributeError: module 'numpy' has no attribute 'ComplexWarning'

The problem is located in the code at the following line https://github.com/uchicago-cs/deepdish/blob/3f2dff7a03f1b31f6924b665ad5b8c299329c1cd/deepdish/core.py#L8C1-L8C51

warnings.simplefilter("ignore", np.ComplexWarning)

Could you please address this issue by either:

1. Removing the reference to np.ComplexWarning from your code.
2. Adding a compatibility check, such as: if hasattr(np, 'ComplexWarning'): warnings.simplefilter("ignore", np.ComplexWarning)

This change will help ensure compatibility with newer versions of NumPy.

Best regards,
Jean-Christophe

Another compatibility issue with numpy 2 using the example of the tutorial:

import deepdish as dd
d = {'foo': np.arange(10), 'bar': np.ones((5, 4, 3))}
dd.io.save('test.h5', d)

AttributeError: np.unicode_ was removed in the NumPy 2.0 release. Use np.str_ instead

I was also able to reproduce this issue on numpy@2.0.2
