I am trying to use the python package autograd and I want to use values of an autograd arraybox in an interpolation
np.interp(x, x_values, y_values)
where y_values are store in an autograd arraybox. This leads to an error
TypeError: Cannot cast array data from dtype('O') to dtype('float64') according to the rule 'safe'
which is connected to the fact the y_values is an autograd arraybox. I don't understand why I get this error, since I thought that autograd should work with numpy? But ok if I can convert the autograd arraybox into a numpy array I can work with that, but that does not seem to work either?
floats = [float(x) for x in y_values]
leads to
TypeError: float() argument must be a string or a number, not 'ArrayBox'

I did:
myvariable._value
and I got an array with the values inside the ArrayBox, which then I could manipulate.
I figured it out after checking the attributes of the ArrayBox using call(myvariable). Looks it is not documented anywhere. Hope it helps
