Fresh installation does not work on cleanly installed Ubuntu1804

Bug Report

Plain installation onto Ubuntu 1804 failed. Can not believe it is failing at such basic level: Instruction: Official Python packages ONNX released packages are published in PyPi.

pip install numpy protobuf==3.16.0 pip install onnx

Following the instruction:

I spent time building a fresh Ubuntu 18.04 and followed README.md for building ONNX, but no matter how I could not repro your cmake error @gggh000. Your log is incomplete so I cannot tell whether you followed the right steps. As you can see, the error showed that it cannot find protobuf compiler so you need to build protobuf first before building ONNX.

Protbuf installation on Linux is mentioned in the README.md:

git clone https://github.com/protocolbuffers/protobuf.git
cd protobuf
git checkout v3.16.0
git submodule update --init --recursive
mkdir build_source && cd build_source
cmake ../cmake -Dprotobuf_BUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_SYSCONFDIR=/etc -DCMAKE_POSITION_INDEPENDENT_CODE=ON -Dprotobuf_BUILD_TESTS=OFF -DCMAKE_BUILD_TYPE=Release
make -j$(nproc)
make install

I don’t know what the error this line generated: cmake ../cmake -Dprotobuf_BUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_SYSCONFDIR=/etc -DCMAKE_POSITION_INDEPENDENT_CODE=ON -Dprotobuf_BUILD_TESTS=OFF -DCMAKE_BUILD_TYPE=Release. Could you please point out? We are eager to enhance the build document to improve developers’ experience so any valid feedback is appreciated.

After installing protobuf correctly (you can use protoc --version to verify), you should be able to build ONNX from source, or pip install onnx-1.10.0.tar.gz which I gave you, or just pip install onnx because we just released a patch 1.10.1 yesterday to fix the source distribution issue. Besides, If you don’t understand how to build protobuf, there is another option to install/use ONNX by conda-forge.

We are all willing to help if you raise any issue. Every time you bump into an issue, please don’t hesitate to let us know first to save your time. Thanks

@gggh000 thanks, this is also fixed in v1.10.1: https://github.com/onnx/onnx/releases/tag/1.10.1
