      Check whether there is any inplace operation affecting gradient calculation. (#27901) · 865a4598
      liym27 提交于
      * Add a class TensorInplaceVersion to count the inplace version and put it in framework::Tensor instead of Allocation or Variable.
      
      * Add a new attribute `_inplace_version` for VarBase.
      
      * Raise exception if an inplace operation can result in incorrect gradient computation.
      
      * Add a new interface _bump_inplace_version() for VarBase to bump the version whenever the Tensor is modified through an inplace operation.
      
      * For api assign, call _bump_inplace_version() when it's an inplace operation inn dynamic mode.
      
      * Use original var_wrapper if the inplace_version is not changed.
      
      * Replace SnapshotVarWrapperList with SnapshotVarWrapper to optimize performane.

      Add Support for SelectedRows for Transpose OP and Fix a Bug That SelectedRows... · d8fe517b

      Add Support for SelectedRows for Transpose OP and Fix a Bug That SelectedRows Cannot be Supported in SimNet (#25536)
      
      This PR fixes a bug that SelectedRows cannot be supported in SimNet. The reason of this bug is that dygraph basic_engine didn't copy var's type when the var needs to be accumulated during backward. So when a var is SelectedRows and needs to be accumulated, like SimNet which calls net for two times, the var's type will be changed to default LoDTensor thus bug happens. To fix it, we just also copy the type.
      
      Without this PR, the accumulated SelectedRows parameters in dygraph will be changed into LoDTensor. So when we fixed the bug of supporting SelectedRows in SimNet, we found `test_imperative_lod_tensor_to_selected_rows` failed and threw the error that SelectedRows was not supported for Transpose OP. To fix it, too, this PR also added support for SelectedRows for Transpose OP.
