Use of deprecated numpy.object

[ParticularlyPythonicBS]

Several parts of the math package use np.object , which is deprecated in the latest version of numpy. This results in an attribute error whenever the phiflow package is imported. AttributeError: module 'numpy' has no attribute 'object'

The error can be fixed by changing np.object usages to np.object_ as per numpy documentation
