When I am trying to run this on Colab

!bash /content/CompositionalGAN/scripts/chair_table/train_objCompose_paired.sh

It gives following error

THCudaCheck FAIL file=/pytorch/aten/src/THC/THCGeneral.cpp line=50 error=38 : no CUDA-capable device is detected
Traceback (most recent call last):

Please help. Thank you.
