## Description ## Solve https://github.com/apache/incubator-mxnet/issues/20371 ## Checklist ## ### Essentials ### - [x] PR's title starts with a category (e.g. [BUGFIX], [MODEL], [TUTORIAL], [FEATURE], [DOC], etc) - [x] Changes are complete (i.e. I finished coding on this PR) - [x] All changes have test coverage - [ ] Code is well-documented ## Comments ## - When the input's shape=(), the backward log_sigmoid activation is incorrect - Reason: For `y = log_sigmoid(x)`, the inputs for `log_sigmoid_grad` is `(dy, y)`. This problem is similar to https://github.com/apache/incubator-mxnet/issues/10868 - There is an error when run the log_sigmoid in gpu. - Reason: There is no cudnn log_sigmoid implement in `cudnn_activation-inl.h` https://github.com/apache/incubator-mxnet/blob/da4ff3a4dc0bd6a54af3d75c492021d18ba1867b/src/operator/nn/cudnn/cudnn_activation-inl.h#L48-L70 -- This is an automated message from the Apache Git Service.
