Hi, what is the resolution of image from your camera?

frankSARU commented 3 years ago

Hi there, I meet the same problem now and I'm using intel D435i camera. I never meet this error before, have you resolve your problem?

Hi, I also meet the same problem now ，but I don't know how to correct errors, some people say maybe my numpy is too high ,but I try to reduced version, the problem remains .
