I am replicating the Vid2Dopler project. VIBE is the first step in the pipeline. However, the version of the related dependency package is too low to run on NVIDIA GeForce RTX 4090. I changed the configuration to Conda install pytorch=1.7.0 torch vision=0.8.0 torch studio=0.7.0 cudatoolkit=11.0- c pytorch. I reported the following error. Is there a kind-hearted person who can help me？

@Sunwenxin1 Just remove the "--display" from the command used to run the demo. You will still get the mp4 video output and the pickled results.
