Hi, I am training the Panoptic model on my custom dataset and registering my dataset using panoptic separated. When I try to run it on a GPU for training It throws "RuntimeError: CUDA error: device-side assert triggered" when I run the training on the CPU it completes the training successfully but at the time of evaluation it gives the mentioned error.

## Expected behavior:

If there are no obvious error in "full logs" provided above,
please tell us the expected behavior.
It Should Evaluate successfully
## Environment:

Provide your environment information using the following command:
```
I am using COLAB Environment
wget -nc -q https://github.com/facebookresearch/detectron2/raw/main/detectron2/utils/collect_env.py && python collect_env.py
```

If your issue looks like an installation issue/environment issue,
please first try to solve it yourself with the instructions in
https://detectron2.readthedocs.io/tutorials/install.html#common-installation-issues

Start by reproducing the failure with the shown register_coco_panoptic_separated call and the DefaultTrainer/DefaultPredictor configuration. Inspect the metadata for floor_Images_data6_separated and the evaluation path around MetadataCatalog and draw_panoptic_seg_predictions, then compare the reported stuff_classes access with the available keys. Done means GPU training and CPU evaluation complete without the CUDA assertion or metadata error.
