I have a situation where I am copying weights back and forth between two instances of the same model. Unfortunately, copy.deepcopy is not working for me. I am having to do:
mp = list(model.parameters())
mcp = list(model_copy.parameters())
n = len(mp)
for i in range(0, n):
    mp[i].data[:] = mcp[i].data[:]

While this is fine, I wonder why deepcopy function is not working.
