Training example failed

[haoyangz]

I downloaded the example data with data.sh and tried to train a toy model with train.sh. Here is the error msg I got:

During handling of the above exception, another exception occurred:

Apply node that caused the error: GpuDot22(GpuElemwise{mul,no_inplace}.0, <CudaNdarrayType(float32, matrix)>)

Any ideas?
