How could I set the data size? I used smaller batch_size, but it lead to the same problem.

Thank you for your reply! But I still met the same problem though I used`train_op = tf.train.AdamOptimizer(learning_rate).minimize(tf_loss,aggregation_method=tf.AggregationMethod.EXPERIMENTAL_ACCUMULATE_N)` or `train_op = tf.train.AdamOptimizer(learning_rate).minimize(tf_loss, aggregation_method=tf.AggregationMethod.EXPERIMENTAL_TREE)`

Thank you for your reply. I can run successfully. Here is another question, I want to use GPU tensorflow because of the long training time. But it appeared a big...
