• Is there a `tensor` operation or function in Pytorch that works like cv2.dilate in OpenCV?
• Pytorch 0.4.0: There are three ways to create tensors on CUDA device. Is there some difference between them?
• Pytorch: Why is the memory occupied by the `tensor` variable so small?
• Why Pytorch officially use mean=[0.485, 0.456, 0.406] and std=[0.229, 0.224, 0.225] to normalize images?
