Errors when trying to build CTNK. No rule to make target: onnx-ml.pb.o

[senatorbard]

I am attempting to build CNTK. I originally installed it the easy through Python Pip. But, I was having errors. After researching the issue online, I concluded that the problem was that my CPU doesn't handle SSE4.1. It only uses SSE2 and SSE4a. (I honestly don't know what this means.) Anyway, I altered the CNTK Makefile SSE tags. So when I try to build CNTK, it doesn't work. In case you are wondering, I have been following the instructions from here: https://docs.microsoft.com/en-us/cognitive-toolkit/setup-cntk-on-linux.

I think this is the error message that is relevant, but I'm not sure. I'm not very knowledgeable about this kind of installation. But I think this is the culprit. Does anyone know the solution?

In my case Source/CNTKv2LibraryDll/proto/onnx/onnxruntime was empty. even after updating onnx with following command

git submodule update --init Source/CNTKv2LibraryDll/proto/onnx/onnx_repo

it doesn't update or copy onnxruntime, which is separate repo. I removed onnxruntime directory and then cloned from https://github.com/Microsoft/onnxruntime.git

Buiild went forward..

Thanks for your reply. I'm trying your method, but getting the same results. My guess is that I didn't follow your instructions properly.

Where do I find the original onnxruntime directory? When I clone onnxruntime.git do I need to be in a certain directory or do I just run the clone command from the home directory?

Sorry - I can handle typical programming, but, as funny as this may sound, installing software on ubuntu is the most difficult process in the universe for me.

Hope this helps...

Assuming cloned cntk repo from git is in /cntk in my case (/home/trainer/Repos/cntk) lets call it ${CNTKDIR}

$(CNTKDIR)/Source/CNTKv2LibraryDll/proto/onnx/onnxruntime is supposed to have onnx related source in this directory. As cntk supports onnx. When I checked error, I found that make was failing to find files in this directory. Figured it was not cloned by any previous attempts, I am not sure why, I am relatively new to git. (You can keep following link on github 'cntk/Source/CNTKv2LibraryDll/proto/onnx/onnx_repo' and see its a separate project/repo). Ok, here is what I did:

1. Delete onnxruntime directory from $(CNTKDIR)/Source/CNTKv2LibraryDll/proto/onnx

cd $(CNTKDIR)/Source/CNTKv2LibraryDll/proto/onnx/ rm -r onnxruntime

2. Clone onnxruntime repo from git in .../onnx/ directory

   cd $(CNTKDIR)/Source/CNTKv2LibraryDll/proto/onnx git clone https://github.com/Microsoft/onnxruntime.git

3. Restart build (debug or release whichever you are trying to build)

   cd $(CNTKDIR)/build/release make -j

Dude - you are the man. Thanks a million.

I tried this, but am getting this error:

make[1]: Leaving directory '/cntk'

Any ideas?

I did it this way.

cd cntk
git submodule update --init Source/CNTKv2LibraryDll/proto/onnx/onnxruntime
