Value 'float64' is not a supported primitive type

[joamatab]

What is the best work around for supporting float64 objects?

import numpy as np
from omegaconf import OmegaConf

d = OmegaConf.create(dict(a=np.float64(3.2)))
d

raises

Well float64 and python float are c doubles underneath, so one should not lose info by converting to/from python floats, like:

d = OmegaConf.create(dict(a=np.float64(3.2).item()))

Alternatively if you didn't mind conversion overhead but wanted a non lossy intermediate string representation, one could use hex float strings like:

d = OmegaConf.create(dict(a=np.float64(3.2).hex()))

np.floats are not supported by OmegaConf. as @pixelb pointed out you have to convert them to a python float.

There is a feature request to attempt supporting them by casting them to float (#725).
