Hi,

I’m trying to run my pvbatch script on a GPU but with no success, I’m using:

`pvbatch --egl-device-index=$CUDA_VISIBLE_DEVICES test.py`

and I get:

```auto
e[0me[31m( 0.525s) [pvbatch] :0 FATL| Signal: SIGSEGVe[0m
error: exception occurred: Segmentation fault

```

Any idea on how to solve?

Regards

What does `$CUDA_VISIBLE_DEVICES` contains ?

It is pretty strange but the `$CUDA_VISIBLE_DEVICES` is not in my environment when I execute the code, the code is executed via slurm and nvidia module is loaded correctly as well as the GPU but the variable is not setted, is there a way to set it up by myself?
