ValueError: Only call `softmax_cross_entropy_with_logits` with named arguments (labels=..., logits=..., ...)

在跑tensorflow事例時

$ python /Users/miao/anaconda/lib/python2.7/site-packages/tensorflow/models/image/mnist/convolutional.py

報如下錯誤

ValueError: Only call `softmax_cross_entropy_with_logits` with named arguments (labels=..., logits=..., ...)

 

需要將源碼中

  loss = tf.reduce_mean(tf.nn.sparse_softmax_cross_entropy_with_logits(
      logits, train_labels_node))

修改為

  loss = tf.reduce_mean(tf.nn.sparse_softmax_cross_entropy_with_logits(
      logits=logits, labels=train_labels_node))
