np.frombuffer is not often used, and I'm not sure if it's been updated
for the new py3 buffer protocol. (The old buffer protocol only
supported 1d buffers.)
Have you tried just using np.asarray? It seems to work fine with
multidimensional memoryview objects at least, which use the new buffer
protocol:
In [12]: a = np.ones((2, 3))
In [13]: a_buf = memoryview(a)
In [14]: a_buf
Out[14]: <memory at 0x7ffd071a2d60>
In [15]: np.asarray(a_buf)
Out[15]:
array([[ 1., 1., 1.],
[ 1., 1., 1.]])
