bytearray(tensor) behaves very differently from bytearray(tensor.numpy())

[vadimkantorov]

import torch

a = torch.ShortTensor([10000])
print(bytearray(a.numpy()))
# bytearray(b"\x10\'")

print(bytearray(a))
# bytearray(b'\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00 ............')

I thought this is the Python prescribed interface of getting byte representation of some object, but this fails with PyTorch arrays. My goal is to pass the obtained byte array or byte string to webrtcvad method working with audio byte frames.

I think it would be good to make the behavior consistent (including bytes)

Same problem with bytes(...) method

However, with torch.ByteTensor, it seems to work okay
