不加上这句的话，运行时会报如下警告。不过，运行结果都没啥问题…

WARNING:tensorflow:Error encountered when serializing global_step.
Type is unsupported, or the types of the items don't match field type in CollectionDef.
'Tensor' object has no attribute 'to_proto'

PS:執行過程中可能會有warning:

‘list’ object has no attribute ‘name’
WARNING:tensorflow:Error encountered when serializing lstm_output_embeddings.
Type is unsupported, or the types of the items don’t match field type in CollectionDef.

應該不用擔心，還是能夠繼續執行的，後面也不受影響

This warning shouldn't impact your training, this is just linked with variable serialization when saving the model, I will check what is wrong there.
In general, LSTM performs better than simpleRNN as they can 'remember' information longer, that can explain the difference in accuracy you noticed.

WARNING:tensorflow:Error encountered when serializing LAYER_NAME_UIDS.
Type is unsupported, or the types of the items don't match field type in CollectionDef.
'dict' object has no attribute 'name'

However, a metagraphdef does export and I am able to successfully use it to recreate the trained model. After playing around with simpler architectures, it looks like the problem comes from the average pooling I do at the end, which involves a call to tf.contrib.layers.avg_pool2d. For a trivial example that elicits this warning, please see the script at
