[pytorch][on device quant] Finalize method for ondevice quant (#83571)
Summary:
After inserting quant dequant nodes in the graph, we need
1. Insert packed param creation and quantized op
2. Create packed_params attribute in the top module. For this we need
graph that inlined except for calculate_qparams method calls. But they
can be inlined too. So perhaps we need to make sure no other callmethods
exist.
3. Insert SetAttr for the packed param
4. Insert GetAttr for the packed param
5. Use GetAttr output for quantized op where applicable, e.g.
linear_dynamic
The above is added to quantize_<method-name> method created inprevious
step. Once the above steps are done clone the method into
quantized_<method-name>
Modify quantize_<method-name>:
1. Remove all outputs from the method.
2. Run dce
3. Remove all inputs from the method except self.
Modify quantized_<method-name>:
1. Remove all packed_param setAttr nodes.
2. Run dce.
This should result in removal of all nodes that generate packed param.
