xuwei06	0bfa1f7c7a	Enforce drop_empty_grad=false When the input of an op is duplicable. ... For input argument with a list of variables, drop_empty_grad is not allowed because it makes the correspondence bewteen a variable and its gradient ambiguous. Use REGISTER_OP_EX to register the op or call InputGrad(?,false) in GradOpDescMaker.	7 years ago

Yu Yang	0a32e74d13	Rewrite StaticRNN with Executor (#5224) ... * Init commit * Make executor use ProgramDescBind * Change Attribute from BlockDesc to BlockDescBind * Since we will get the program desc in RNN, just BlockDesc is not enough. * Add DeviceContext to Executor API * Rewrite RNN * Pass Python * AddBiasOp does not care num_flatten_dims * Stash * Fix MacOS Compile * Pass RNN forward * add python test * refactor test * Make compile pass * add gradopmaker * First draft done * Polish code * add grad op maker and grad infershape * Polish code * Fix backward.cc bug * Fix infershape * Rename function * add backward test * simplify recurrent test * Update * Pass unittest * Add comments & refine test * Add comments * refactor test * Complete Unittest * fix StepScopes enforce * Remove unused unittest * no type error * Update * Make RNN Pass unittest	7 years ago
Yu Yang	4df6cf4d16	Rewrite feed/fetch op (#4815) ... * Feed/Fetch op just plain operator, not a OpWithKernel * Do not register OpInfoMaker since Feed/Fetch will never be configured by users * Feed/Fetch op has empty gradient * Feed/Fetch op do not hard code `feed_variable`, `fetch_variable` as its input and output, make it as a plain Operator input/output	7 years ago
