请注意,下面问题中的代码也包含在上面的While语句中
with tf.name_scope("Learning"):
with tf.name_scope("Reduce_Mean"):
Loss = tf.reduce_mean(tf.nn.softmax_cross_entropy_with_logits_v2(logits=Logits, labels=GMD_Miss_Y))
错误是
ValueError: Cannot reshape a tensor with 3 elements to shape [1] (1 elements) for 'Learning/Reduce_Mean/softmax_cross_entropy_with_logits/Reshape_2' (op: 'Reshape') with input shapes: [3], [1] and with input tensors computed as partial shapes: input[1] = [1].
