Is this code a part of the obfuscated Python code contest? As we don't know where the error occurs because you did not post the exception traceback, let us suppose that after J4 = csr.to_numpy(), J4 is an numpy array of integers, then after for i in J4, i is an integer. An integer is not iterable, so you can't write for j in i.

The solution is to not iterate on an integer. Do not write for j in i if i is an integer.

for j in range(i): should get you past your dilemma, but you are sure to be back with more problems if you don't change your variable naming conventions. Unreadable!
