Issue
I'm trying to install onnx in a fresh Ubuntu 20.04 install, but I'm running into the error bellow. It seems that I need the protobuf compiler, although I haven't found any documentation that says that I need that package installed.
$ sudo python3 -m pip install 'onnx>=1.1.2'

Then I tried installing the protobuf compiler (sudo apt install protobuf-compiler) and now I get this other error, which seems to indicate that some script in the installation process requires a python binary. Since this is Ubuntu 20.04, no python 2.7 is installed and no python binary exists.

To circumvent this issue a symbolic link can be made so that the python command actually runs python3.
Solution
In summary, to install onnx successfully in Ubuntu 20.04, you'll need to:
1) Install protobuf-compiler: sudo apt install protobuf-compiler
2) Make a link from python3 to python: sudo ln -s /usr/bin/python3 /usr/bin/python
Note: Maybe I missed another dependency, I already installed a bunch of other packages while installing the OpenVINO dependencies.
