After installing, pytorch and torchvision as described in here, I installed detectron2 as python -m pip install 'git+https://github.com/facebookresearch/detectron2.git'. All of this produced no errors. But only when I run the inference, the error appears. The full error msg is as follows

Interestingly it appears only in my jetson agx orin using conda. In my laptop, if I install pytorch and torchvision in a conda environment, it doesnt come up
