Difference In Padding Integer And String In Keras

I'm trying to pad a text for a seq2seq model. from keras_preprocessing.sequence import pad_sequences x=[['Hello, I'm Bhaskar', 'This is Keras'], ['This is an', 'experiment']] pad_

Solution 1:

As suggested by the Error, change dtype to object(not string but to an object itself), It will do the job for you.

from keras.preprocessing.sequence import pad_sequences

x=[["Hello, I'm Bhaskar", "This is Keras"], ["This is an", "experiment"]]
pad_sequences(sequences=x, maxlen=5, dtype=object, padding='pre', value="<PAD>")

Output

array([['<PAD>', '<PAD>', '<PAD>', "Hello, I'm Bhaskar", 'This is Keras'],
       ['<PAD>', '<PAD>', '<PAD>', 'This is an', 'experiment']],
      dtype=object)
