Live inference using webcam doesn't work

Hi @fahiar10, it isn’t due to a blockage in feature availability, but rather due to the image shape being passed to roboflow.js – as you see in the error log, the expected shape is [1, 3, 640, 640], but it is being passed in as [1, 640, 640, 3]

  • [1, 3, 640, 640] - refers to: 1 image or video frame, with 3 channels (R, G and B), at a size of 640 width and 640 height

I’ll add this to our current bug report for the team.

In the meantime, if you use a Roboflow Train credit to train a model version, roboflow.js will work for you.

Another option is to use one of the scripts I have here in this repository to run inference: https://github.com/roboflow/computer-vision-utilities

Here is the video inference script for object detection:

  1. On a webcam stream: roboflow-computer-vision-utilities/draw_stream.py at main · roboflow/roboflow-computer-vision-utilities · GitHub
  2. On a video file: roboflow-computer-vision-utilities/draw_vid.py at main · roboflow/roboflow-computer-vision-utilities · GitHub
