I am trying to deploy the YOLOv4 tiny Darknet object detection model on an HPC.

I have trained and tested the YOLOv4-tiny model on Google Colab with no issues. Now I am trying to move the model to an HPC platform. The model trains well on a custom dataset on the HPC and can detect objects in images when tested. However, whenever I try detection for videos, the model freezes after displaying model architecture information. Nothing happens

The command I am using is:

./darknet detector demo data/obj.data cfg/custom-yolov4-tiny-detector.cfg backup/custom-yolov4-tiny-detector_final.weights -ext_output vidtest.mp4 -i 0 -out_filename results/outvids.mp4 -dont_show

I have no clue why this might be happening. I have tried renaming the videos, using the .avi extension for the output as suggested in related posts but could not get it fixed.

I would appreciate some help with this.
