ValueError: array length 2 does not match index length 0 python code example

Example: ValueError: array length 2 does not match index length 0 python

# You may be getting array mismatch error because of the index the series contains. 
# So reset the index earlier or pass only the values i.e

result_frame = pd.DataFrame({'index': test_subdata['id'].values, 
							 'match_1': m1, # indirectly related series
                             'pred1': predicciones['pred1'].values})
