Google colab keeps on crashing while using pyyolo

[ramgarg102]

The modal keeps on crashing. I am using pyyolo to detect objects in a video. But every time after two detections, the kernel crashes and restarts.

It might be a google colab issue. Did you try to run it on your local machine because I haven't tested it using Yolov4? Can you ensure you can make it work locally?

[ramgarg102]

I asked the same to folks at colab. They asked me to ask you guys. I can't do it on a local machine because my GPU does not support CUDA. It's an Intel GPU.

You actually don't need a GPU to run Darknet. You can compile Darknet without GPU support. For example in Linux,
https://github.com/AlexeyAB/darknet/blob/0a42f8d6144a0a388b1da238fe078af981d07be0/Makefile#L1-L3
if these lines are 1 replace them with 0 and then recompile.

Is pyyolo only compatible with yolov3 or works also for yolov4?

It just reads weights and configuration, it should work with YOLOv4 too.

[ramgarg102]

It's just an observation. I tried it with both yolov3 and yolov4 weights and cfg. The pyyolo works just fine with yolov3 but with yolov4, the session crashes even before the detection starts. I think it needs to be tweaked to work with yolov4 weights. Anyway, it is an amazing tool and keep up.

Can you try with the recent update? Updated it to work with the recent darknet repo, tested with the Yolov4 and it works for me.

[ramgarg102]

It's working perfectly now with yolov4 weights also. Thanks for the update.
