8 years ago 500 epochs is just an arbitrary number I kill the process much earlier than that.
Running against GPU memory problems is very common. The main differences between GPU cards is their memory size which is sometimes more important than speed. The Mac GPU is too small and some of its memory is used by OS X to generate your screen. Try running on AWS with g2.x2large machine.
You can reduce batch_size until it fits GPU memory. You can also try smaller model size (less rnn layers and nodes) and see what happens. The model parameters I used are also somewhat arbitrary.

First off, thanks for this share. This NLP stuff is really cool, but can be overwhelming. This project has helped immensely in helping me to better understand. Unfortunately, it seems troubleshooting these models and implementations is almost an art in itself.
So I am currently using Tensorflow and I wrote a scraper to pull data from Buzzfeed to act as my training set since the reuters data didn't seem to be enough due to glove containing 40k vocab. When I was running against the CPU, all worked fine but in a period of about 7 hours, I only made it through about 4 iterations out of 500. So I have attempted to jump over to using the GPU. I am running on a Mac with an Nvidia 650M and 1 GB of VRAM. So I am aware that this isn't the best of hardware, but I believe it still should be doable right?
So when I run the train.py file (converted from ipynb), I am getting the below OOM error. I know you have been using Theano, so if you aren't sure then just disregard. However if you know how I may be able to overcome this issue I'd love to hear it. It seems to be erroring out around cell 30. What is baffling to me is that it says total memory is 1023.MiB but free is 49.Mib. As I run each time it reduces. Now I saw in tF forums that Tensorflow allocates all GPU and that you really can't tell how much is free because it is managed internally....so maybe this is nothing. I was trying to figure out how to flush the GPU mem but I haven't had any luck with that either. Even after restarting the mac, I still see about the same thing.
I have tried adjusting the training sample size and some of the other variables to see if I could get it to just run through even once but it still ends up crashing with an OOM error. My next thing I am going to try is getting the TF summarizer working so perhaps I might be able to get a bit more insight via tensorboard. I do have a much better GPU on my PC, but I will need to set this all up in a docker vm or something if I take that approach. However if it works, I will be happy.
If you have any insight, please send it my way. Thanks again!!
