WebOct 25, 2024 · Hello everyone, We have some problems with the shuffling property of the dataloader. It seems that dataloader shuffles the whole data and forms new batches at the beginning of every epoch. However, we are performing semi supervised training and we have to make sure that at every epoch the same images are sent to the model. For example … http://www.idris.fr/eng/jean-zay/gpu/jean-zay-gpu-torch-multi-eng.html
