error when running demos #20

Closed yxt132 closed 4 years ago

yxt132 commented 4 years ago

when I run the python demo using the command python demo.py --model human-pose-estimation-3d.pth --video 0

I got the following error. I am running it within Anaconda on my MacOS 10.13. Running with the OpenVino option gave me similar error.

I was able to access my camera by using a little test script. So there should be no problem there. Any idea how to solve it? Thanks!

Hi, do you use OpenCV to check if camera works? I suggest to try other values instead of 0, e.g. 1, or 2, or 3...

Thank you for your quick response! Yes, I did verify that the camera works using OpenCV. I think the problem lies somewhere else but not figured out yet.

Daniil-Osokin commented 4 years ago

That is strange, because demo also uses OpenCV, so behavior should be similar.

Hope, it works.
