Load() resets file offset unconditionally #3694
Description
As opposed to torch.save() and the pickle api, load() resets the position pointer of the file to zero. This keeps the following from workgin
import tempfile
import torch
import pickle
a = torch.zeros(2, 2)
with tempfile.TemporaryFile(mode='w+b') as tmp:
i = 41
pickle.dump(i, tmp)
torch.save(a, tmp)
tmp.seek(0)
j = pickle.load(tmp)
b = torch.load(tmp)
