Web8 sep. 2024 · 1 Answer. Allocating GPU memory is slow. PyTorch retains the GPU memory it allocates, even after no more tensors referencing that memory remain. You can call torch.cuda.empty_cache () to free any GPU memory that isn't accessible. While this explains a lot of things, sadly this only works with separate runs.

Web19 mei 2024 · IoU formula and then the average is done over the classes to get the mIoU. However, I don't understand what happens for the classes that are not represented. The formula becomes a division by 0, so I ignore them and the average is only computed for the classes represented. Web2 mrt. 2024 · I'm trying to wrap my head around this but struggling to understand how I can compute the f1-score in an object detection task. Ideally, I would like to know false positives, true positives, false negatives and true negatives for every target in the image (it's a binary problem with an object in the image as one class and the background as the other class).
