WebMay 20, 2024 · This happens because we used to have only uint8 type to represent boolean and were using them as masks. Now that we introduced bool dtype for that purpose, we are deprecating the use of uint8 as a bool. You can remove it by changing your uint8 Tensor to a boolean one before using it as a mask when indexing. WebThe u-int-8 stands for: U: Means: Unsigned Which means: All values are positive (no negative "sign" allowed).
