❓ Questions and Help

Hi, I tried to run the webcam.py demo, but it occurs this problem, I am wondering what's wrong with it?

Thanks!

I think you might have a problem with OpenCV not being able to read from your webcam. See https://stackoverflow.com/questions/21043394/opencvs-video-capture-not-returning-an-image for more information.

I'm closing this issue as this is not a problem with maskrcnn-benchmark

I checked my gcc version

and I am wondering why I still cannot run simple demo. TAT

I'd recommend uninstalling maskrcnn-benchmark, deleting the build folder and installing again, making sure that you are using the same python environment for compiling and for running the code
