Unspecified launch failure #127

Closed IouJenLiu closed 8 years ago

IouJenLiu commented 8 years ago

Hi,

When I run

th train.lua -input_h5 coco/cocotalk.h5 -input_json coco/cocotalk.json,

I got the following error message randomly:

"THCudaCheck FAIL file=/tmp/luarocks_cutorch-scm-1-6961/cutorch/lib/THC/generic/THCStorage.c line=147 error=4 : unspecified launch failure"

Sometimes the error message occurs after 50000 iterations, sometimes it occurs around 8000 iterations. After getting the "unspecified launch failure", I tried to run the train.lua script again. Then, I get the error message: "all CUDA-capable devices are busy or unavailable". I have to restart the computer to run the script again. Does anyone have the same problem?

Thank you!

Using a GPU for both computing and display leads to Unspecified launch failure error.
