Bug#993004: yt: tests fail with h5py 3

[Drew Parsons]

Source: yt
Version: 3.6.1-1
Severity: serious
Justification: breaks

yt tests fail with h5py 3, due to removal of the values property.

        if "dataset_units" in h5f:
            for unit_name in h5f["/dataset_units"]:
                current_unit = h5f["/dataset_units/%s" % unit_name]
>               value = current_unit.value
E               AttributeError: 'Dataset' object has no attribute 'value'



yt has addressed it upstream, upgrade to yt 4 should fix it.
