Classes
struct	mxnet::OpContext
	All the possible information needed by Operator.Forward and Backward This is the superset of RunContext. We use this data structure to bookkeep everything needed by Forward and Backward. More...
class	mxnet::OpStatePtr
	Operator state. This is a pointer type, its content is mutable even if OpStatePtr is const. More...

Namespaces
	mxnet
	namespace of mxnet

Typedefs
using	mxnet::FCreateOpState = std::function< OpStatePtr(const NodeAttrs &attrs, Context ctx, const std::vector< TShape > &in_shape, const std::vector< int > &in_type)>
	Create a Layer style, forward/backward operator. This is easy to write code that contains state. OpStatePtr is a pointer type, it's content is mutable even if OpStatePtr is constant. More...
using	mxnet::FExecType = std::function< ExecType(const NodeAttrs &attrs)>
	Execution mode of this operator. More...
using	mxnet::FStatefulCompute = std::function< void(const OpStatePtr &state, const OpContext &ctx, const std::vector< TBlob > &inputs, const std::vector< OpReqType > &req, const std::vector< TBlob > &outputs)>
	Resiger a compute function for stateful operator. OpStatePtr is a pointer type, it's content is mutable even if OpStatePtr is constant. More...
using	mxnet::FStatefulComputeEx = std::function< void(const OpStatePtr &state, const OpContext &ctx, const std::vector< NDArray > &inputs, const std::vector< OpReqType > &req, const std::vector< NDArray > &outputs)>
	Resiger a compute function for stateful operator using NDArray interface. OpStatePtr is a pointer type, it's content is mutable even if OpStatePtr is constant. More...
using	mxnet::FResourceRequest = std::function< std::vector< ResourceRequest >(const NodeAttrs &n)>
	The resource request from the operator. An operator could register ResourceRequestEx, or ResourceRequest, or neither. More...
using	mxnet::FResourceRequestEx = std::function< std::vector< ResourceRequest >(const NodeAttrs &n, const int dev_mask, const DispatchMode dispatch_mode)>
	The resource request from the operator. An operator could register ResourceRequestEx, or ResourceRequest, or neither. More...
using	mxnet::FNDArrayFunction = std::function< void(const nnvm::NodeAttrs &attrs, const std::vector< NDArray > &inputs, std::vector< NDArray > *outputs)>
	Register an operator called as a NDArray function. More...
using	mxnet::FCompute = std::function< void(const nnvm::NodeAttrs &attrs, const OpContext &ctx, const std::vector< TBlob > &inputs, const std::vector< OpReqType > &req, const std::vector< TBlob > &outputs)>
	Resiger a compute function for simple stateless forward only operator. More...
using	mxnet::FComputeEx = std::function< void(const nnvm::NodeAttrs &attrs, const OpContext &ctx, const std::vector< NDArray > &inputs, const std::vector< OpReqType > &req, const std::vector< NDArray > &outputs)>
	Resiger an NDArray compute function for simple stateless forward only operator. More...
using	mxnet::FInferStorageType = std::function< bool(const NodeAttrs &attrs, const int dev_mask, DispatchMode *dispatch_mode, std::vector< int > *in_attrs, std::vector< int > *out_attrs)>
	Resiger a storage and dispatch mode inference function based on storage types of the inputs and outputs, and the dev_mask for the operator. More...
using	mxnet::FQuantizedOp = std::function< nnvm::NodePtr(const NodeAttrs &attrs)>
	Register a quantized node creation function based on the attrs of the node. More...
using	mxnet::FNeedRequantize = std::function< bool(const NodeAttrs &attrs)>
	Register a function to determine if the output of a quantized operator needs to be requantized. This is usually used for the operators taking int8 data types while accumulating in int32, e.g. quantized_conv. More...
using	mxnet::FAvoidQuantizeInput = std::function< bool(const NodeAttrs &attrs, size_t index)>
	Register a function to determine if the input of a quantized operator needs to be quantized. This is usually used for the quantized operators which can handle fp32 inputs directly. More...

Enumerations
enum	mxnet::OpReqType { mxnet::kNullOp, mxnet::kWriteTo, mxnet::kWriteInplace, mxnet::kAddTo }
	operation request type to Forward and Backward More...
enum	mxnet::ExecType { mxnet::ExecType::kSync, mxnet::ExecType::kAsync, mxnet::ExecType::kCrossDeviceCopy, mxnet::ExecType::kSubgraphExec }
