okei, @smth @albanD  I am finishing training some deep models pretrained on imagenet from  torchvision.model to check everything is ok. After that I will be able to git push. I have followed the standards on the torchvision.datasets. I tried to follow the same guideline. The only thing I miss is some kind of checksum for the downloaded dataset and preprocessing. I have also add some features to the dataset based on numpy operations. I will make that clear in the dataset python class.
