Description
Describe the issue:
According to the documentation of zeros_like
(and related functions), providing dtype
will override the provided data type: https://numpy.org/doc/stable/reference/generated/numpy.zeros_like.html
Basically, my interpretation is that zeros(a.shape, dtype=foo) == zeros_like(a, dtype=foo)
.
This does not seem to be the case for Quantity
from astropy
(and maybe other array libraries sharing some specific mechanism).
(Which caused some issue in Astropy, see astropy/astropy#13276, from a change in Matplotlib, see matplotlib/matplotlib#22929. But more importantly, zeros_like
does not appear to work as stated in the documentation. Not sure if this is a numpy or astropy issue though, but it is the numpy documentation that seems wrong.)
Reproduce the code example:
import numpy as np
import astropy.units as u
a = [1, 2, 3]*u.m
z0 = np.zeros_like(a, dtype=bool)
z1 = np.zeros(a.shape, dtype=bool)
print(repr(z0))
print(repr(z1))
