Hello

I am using Ubuntu 16.04. I tried to run torch-rnn with OpenCL and met the error.

Using NVIDIA Corporation , OpenCL platform: NVIDIA CUDA
Using OpenCL device: Quadro FX 580
Running with OpenCL on GPU 0

ValueError: max() arg is an empty sequence

How should I resolve this problem?

I installed cltorch and clnn and that's it.

Looks like you are running out of memory; the Quadro FX 580 you are using only has 512MB of VRAM. You can try a smaller rnn_size or seq_length.

Thanks

I tried with seq_length=5 but the error still happens (rnn_size=128 as default).
