NoneType' object is not subscriptable

[shane1236]

normaly traceback would have the line numbers and I don't see anywhere in your code cell_name in async-def-wrapper()

This is the problem bro! I couldn't find any line number just this error pop up but the problem still lies in this section as I'm using jupyter thats why I know
def vectorize_sequences(sequences, dimension=10000):
results = np.zeros((len(sequences), dimension))
print(results)
for i, sequence in enumerate(sequences):
results[i, sequence] = 1.
return results
