## pad_sequences “`python keras.preprocessing.sequence.pad_sequences(sequences, maxlen=None, dtype=’int32′, padding=’pre’, truncating=’pre’, value=0.) “` Transform a list of `num_samples` sequences (lists of scalars) into a 2D Numpy array of shape `(num_samples, num_timesteps)`. `num_timesteps` is either the `maxlen` argument if provided, or the length of the longest sequence otherwise. Sequences that are shorter than `num_timesteps` are padded with `value` at
