Dump operator names of a script module (#30467)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/30467
Introduce function jit.export_opnames(module), which returns a list of all operator names used in the module and its submodules. One usage is to have mobile custom build to link only operators in the returned list to save the mobile size.
Example:
import torch
m = torch.jit.load("example.pt")
print(torch.jit.export_opnames(m))
The outputs are in alphabetical order:
['aten::_convolution', 'aten::add.Tensor', 'aten::add_.Tensor', 'aten::addmm', 'aten::append.Tensor', 'aten::cat', 'aten::dropout', 'aten::embedding', 'aten::matmul', 'aten::max.dim', 'aten::mul.Tensor', 'aten::permute', 'aten::relu', 'aten::t', 'aten::tanh', 'prim::ListConstruct', 'prim::TupleConstruct', 'prim::TupleUnpack']
