Error when implementing demo

[RaymonHE]

Hi, @zachteed @lahavlipson, sorry to bother you again. After almost one-week-long, I made some breakthroughs. After I created the virtual environment on my Ubunutu20.04 and succeeded in installing CUDA 11.8 and the corresponding cudnn (8.50 for CUDA 11.X), I finally solved the problem of the failure to download DPViewer, which is not that easy as it sounded, especially for me who might had no background of how to implement learning on Ubuntu before. I still encountered some problems when testing the demo given. After I inputted the python demo.py --imagedir=movies/IMG_0494.MOV --calib=calib/iphone.txt --stride=5 --viz, the outcome is given below. The error is the failure to locate the file "dpvo.pth", I wonder if I miss something or not. I would be very grateful if you could do me a favor. `(dpvo) ➜ DPVO git:(main) ✗ python demo.py --imagedir=movies/IMG_0494.MOV --calib=calib/iphone.txt --stride=5 --viz Running with config...
