Description
Doing a build with Astropy4 I now get failures from verify package relating to YAML serialization.
This works fine with the same version of YAML on Astropy 3 but fails on Astropy 4.
self = <yaml.loader.SafeLoader object at 0x7fbb0063aba8>

The difference seems to be in datum_representer where .value returns a float in astropy3 but numpy.float64 in astropy4.
Astropy 4:
>>> import astropy.units as u
|
>>> import numpy
|
>>> a = 5 * u.s
|
>>> type(a.value)
|
<class 'numpy.float64'>
|
Astropy 3:
>>> import astropy.units as u
|
>>> import numpy
|
>>> a = 5 * u.s
|
>>> type(a.value)
|
<class 'float'>

Tim Jenness, can you test this on your system? I don't have Astropy 4 myself.
Krzysztof Findeisen
added a comment - Tim Jenness , can you test this on your system? I don't have Astropy 4 myself. Tests pass with this. Thank you for the quick fix.
On Astropy 4 for the blob test:
