TENSORFLOW。标签和logits不匹配，但我确信它们具有相同的形状

Question

Traceback (most recent call last):
  File "CNN2.py", line 272, in <module>
    _, l, predictions = session.run([optimizer, cost, y_pred], feed_dict=feed_dict)

ValueError: Cannot feed value of shape (128,) for Tensor 'y_true:0', which has shape '(128, 1)'

Answer 1

您可以将标签值重新整形为(128, 1)

labels  = np.reshape(labels, (128, 1))
feed_dict = {..., y_true:labels}
