Deprecated numpy attributes used

[sybrenstuvel]

Blender 4.1.1 on Win10/64-bit, with BlenderCam 1.0.21.

This is what happens when I press the "Calculate Relief" button in the "Bas Relief" panel:

Traceback (most recent call last):

`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. Did you mean: 'cfloat'?

Workaround

As a workaround, I tried this:

>>> import numpy
>>> numpy.float = numpy.float64

which got rid of the error and seems to work for me.

thanks, it was patched. in my branch.
