Cant print Grad tensor from CTCLoss function

[Adhiraj Banerjee]

when ever i try to print the gradient tensor obtained from gpu_ctc
i am using pytorch
and i am editing the warpctc_pytorch init.py

in the forward function i tried printing the grads tensor but i encounter the following error

i encounter this error

THCudaCheck FAIL file=/pytorch/aten/src/THC/THCCachingHostAllocator.cpp line=278 error=700 : an illegal memory access was encountered
