torchvision.transforms¶. Transforms are common image transformations. They can be chained together using Compose.Most transform classes have a function equivalent: functional transforms give fine-grained control over the transformations. This is useful if you have to build a more complex transformation pipeline (e.g. in the case of segmentation tasks).

Aug 22, 2018 · ToTensor transforms the image to a tensor with range [0,1]. Thus it already implies some kind of normalization. If you want to use the normalization transform afterwards you should keep in mind that a range of [0,1] usually implies mean and std to be around 0.5 (the real values depend on your data).

26.10.2017 · Hi I am currently using the transforms.ToTensor(). As per the document it converts data in the range 0-255 to 0-1. However, the transform work on data whose values ranges between negative to positive values? Any ideas how this transform work. And the transformed values no longer strictly positive. In most tutorials regarding the finetuning using pretrained …
