Thanks for the heads up. But this is a duplicate of issue #885
Using LSTMBlockCell is literally a regex that might be worth doing if implementing cudnn is taking months...

BasicLSTMCell is a reference implementation, it is quite slow and memory inefficient. It would be much better to use https://www.tensorflow.org/api_docs/python/tf/contrib/cudnn_rnn (literally an order of magnitude faster) or at least https://www.tensorflow.org/api_docs/python/tf/contrib/rnn/LSTMBlockCell .
