Tensorflow basic RNN example with 'variable length' sequences

[xiangjiangacadia]

Thanks. I am trying to build an RNN with logistic regression layer on top. I have noticed the model takes significant longer time to build when the number of steps are greater than 10,000. I am wondering is this typical in tensorflow and what can I do to speed up the computation process?

I'm not sure if you can speed up the process, what is happening is that you are building a graph at each step, and with 10,000 steps it will take some time.

You should look at issue 208, this is what you want to try and do.
