Key Error: None of [Int64Index…] dtype='int64] are in the columns

Question

I\'m trying to shuffle my indices using the np.random.shuffle() method, but I keep getting an error that I don\'t understand. I\'d appreciate it if someone could help me puz

Answer 1

You created your scaled_inputs_all DataFrame using loc function, so it most likely contains no consecutive indices.

On the other hand, you created shuffled_indices as a shuffle from just a range of consecutive numbers.

Remember that scaled_inputs_all[shuffled_indices] gets rows of scaled_inputs_all which have index values equal to elements of shuffled_indices.

Maybe you should write:

scaled_inputs_all.iloc[shuffled_indices]

Note that iloc provides integer-location based indexing, regardless of index values, i.e. just what you need.
