Error on running inference on the sample dataset

The environment has been setup as per the instructions in the README, however on running the command (python inference.py --model results/release/semseg/final.ckpt --scenes METAROOT/sample/sample1/info.json) the above error occurs

Have you solved this problem? I ran it in docker and got the same problem.

@Zhiozhio , I was finally able to run it on colab, https://colab.research.google.com/drive/1JCSATIGPHL-AE4S-Qa-jQhhoEY5JNly2?usp=sharing
Not sure about Docker

Hi, I had the same error.
According to the documentation (https://detectron2.readthedocs.io/en/latest/tutorials/install.html#common-installation-issues) the version of detectron2 and torch depends on the CUDA version installed on the computer.
I was able to solve the error by manually adjusting the project dependencies to my CUDA version.
