RuntimeError: make_default_context() wasn't able to create a context on any of the 1 detected devices，RuntimeError: PyCUDA init failed, cannot use torch buffer

Great job!I'm having a bit of an issue with head mode. When I run python train.py --config configs/train_example.yaml --pipeline READ.pipelines.ogl.TexturePipeline --crop_size 256x256, I was able to train successfully and finish evaluating the model. However, when I run python viewer.py --config downloads/kitti6.yaml, I get the following error:

During handling of the above exception, another exception occurred:

I would appreciate it if you could give me a little advice.Thanks
