Error when importing `astropy.nddata.utils.block_reduce`

[ladsantos]

When using astropy v5.1 and I do a import stistools (v1.4.1), I get the following error:

ImportError                               Traceback (most recent call last)

ImportError: cannot import name 'block_reduce' from 'astropy.nddata.utils' (/Users/ldsantos/Applications/miniconda3/envs/dat/lib/python3.9/site-packages/astropy/nddata/utils.py)

Maybe we need to update stistools to be compatible with astropy v5.1?

[ladsantos]

Apparently, for v5.1 the correct import statement should be from astropy.nddata import block_reduce.

[ladsantos]

Ah, never mind, this issue has been corrected in stistools v1.4.2.
