ONNX export not working

[ykim362]

pytorch_translate/examples/export_iwslt14.sh

This example doesn't work for me.
Would you be able to help me to run the example script?

I tried to fix the errors one by one, by removing parameters, but couldn't succeed to export.

I re-trained an RNN model instead of using the pre-trained model because of the name mismatch (version issue?).
"encoder.bilstm.layers.0.weight_ih_l0 vs. encoder.layers.0.weight_ih_l0"

So, I got encoder and decoder pb files.

When I tried to build cpp, it generated error message that Caffe2 is not found.
I installed Caffe2 (pytorch) as in https://caffe2.ai/docs/getting-started.html?platform=ubuntu&configuration=compile.

Could you help me to resolve this issue?

CMake Error at CMakeLists.txt:19 (find_package):
  By not providing "FindCaffe2.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Caffe2", but
  CMake did not find one.

  Could not find a package configuration file provided by "Caffe2" with any
  of the following names:

    Caffe2Config.cmake
    caffe2-config.cmake

  Add the installation prefix of "Caffe2" to CMAKE_PREFIX_PATH or set
  "Caffe2_DIR" to a directory containing one of the above files.  If "Caffe2"
  provides a separate development package or SDK, be sure it has been
  installed.

@ykim362, thanks for the report. I'm in the process of updating the examples. We will also replace the ONNX solution with a PyTorch native export.

[ykim362]

@jmp84 Thanks for the information!

I have one more question.

Replacing ONNX solution with a PyTorch native export

Does this mean Torch Script?
https://pytorch.org/tutorials/advanced/cpp_export.html

Or, another solution?

[jmp84]

@ykim362, yes, I meant Torch Script.

Does the next update support export to Caffe2?
How does export with Torch Script works with Caffe2
