TypeError: Cannot cast ufunc add output from dtype('float64') to dtype('uint8') with casting rule 'same_kind'

See original GitHub issue

I’m using Gizeh library and I get the above error upon installing the latest version of Numpy. There was no error with Numpy version 1.08.

File "animation/target_animation.py", line 161, in draw
    fill = gizeh.ImagePattern(self.bg.data, self.bg.pos, filter='best')
  File "build/bdist.linux-x86_64/egg/gizeh/gizeh.py", line 295, in __init__
  File "build/bdist.linux-x86_64/egg/gizeh/gizeh.py", line 50, in from_image
TypeError: Cannot cast ufunc add output from dtype('float64') to dtype('uint8') with casting rule 'same_kind'

Is there a workaround or would you fix this issue please?

Typically this is code such as a += b and you need to make it np.add(a, b, out=a, casting="unsafe") (if you are sure you want the unsafe cast behaviour. Or, unless b is huge and it is safe, maybe just cast b first.

In my case, I had a similar issue. It was solved as suggested by seberg. I replaced line 40 in gizeh.py:

arr += image.flatten()

with line:

arr = np.add(arr, image.flatten(), out=arr, casting="unsafe")

I hope this helps somebody else.
