python 3 memoryview : unsupported format <d

[evason]

Hi, I have just made the change from python2.7 to python3.5.3.

I am having trouble with following lines of code which works in python2, but not 3:

In [5]: from multiprocessing import sharedctypes

In [6]: x = sharedctypes.RawArray('d', 10)

In [7]: memoryview(x)[:] = array(zeros_like(arange(10.), dtype=float64))

With python3 the error is:

Error:
NotImplementedError: memoryview: unsupported format <d

Can somebody provide a hint on how this is done in python3?

Thanks!
