[FIXED] AttributeError: module 'numpy' has no attribute 'bool'. when importing glumpy

Issue

>>> import glumpy
/home/mona/anaconda3/envs/clean-pvnet/lib/python3.10/site-packages/glumpy/gloo/variable.py:82: FutureWarning: In the future `np.bool` will be defined as the corresponding NumPy scalar.

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

I changed the following file line (clean-pvnet) mona@ada:~/anaconda3/envs/clean-pvnet/lib/python3.10/site-packages/glumpy$ vi gloo/variable.py

bool gl.GL_BOOL 1 gl.GL_BOOL np.bool

to

bool gl.GL_BOOL 1 gl.GL_BOOL np.bool_

and still same error.

It seems the module is not being reloaded despite opening a new terminal tab and conda activate clean-pvnet.

Solution

I only converted one of the np.bools to np.bool_ following a tutorial. I searched for all of them and converted them similarly and error is gone.

(clean-pvnet) mona@ada:~/anaconda3/envs/clean-pvnet/lib/python3.10/site-packages/glumpy$ rg np.bool_
gloo/variable.py
