Feb 09, 2018 · I want to threshold a tensor used in self-defined loss function into binary values. Previously, I used torch.round(prob) to do it. Since my prob tensor value range in [0 1]. This is equivalent to threshold the tensor prob using a threshold value 0.5. For example, prob = [0.1, 0.3, 0.7, 0.9], torch.round(prob) = [0, 0, 1, 1] Now, I would like to use a changeable threshold value, how to do it?

23.04.2020 · Hi Everyone, I have a binary image which is the output of a segmentation net. As part of the post processing I have to find all the connected components in this image, which I do with the openCV connectedComponents function. However I was wondering if there is a pytorch equivalent so I can do this operation while the tensor is still on the GPU.
