We are using the YoloV7 object detection model and want to train it with a custom dataset. Our GPU hardware consists of Nvidia V100. Our dataset includes 60k training images, 2k validation images, and 4k test images. The image resolution is 640x640. We are using a batch size of 16 and 8 workers.
We are encountering a problem during training, which I believe is related to the dataloader. During training, GPU utilization sometimes drops to 0% and at other times increases to 50%-70%, resulting in very long iteration times. One epoch takes almost 50 minutes. I tried increasing the number of workers (16, 24), but it did not fix the issue.
Summary, dataloader cannot transfer data synchronously to GPU. So GPU consumption is decreasing.
