  • Since you feed a (10 x 9) tensor into Y = tf.placeholder(tf.float32, shape=[None,num_labels]), which has shape (batch_size, 7). You need to check the length of Y should be 7 or 9.

In the last line encounter this error message



ValueError: Cannot feed value of shape (10, 9) for Tensor 'Placeholder_2:0', which has shape '(?, 7)'



I tried changing some values but still I cannot fix this error.



What can I do to resolve this error?







python tensorflow machine-learning

  • Since you feed a (10 x 9) tensor into Y = tf.placeholder(tf.float32, shape=[None,num_labels]), which has shape (batch_size, 7). You need to check the length of Y should be 7 or 9.
