I have installed the pybind11 master branch. But still hit this error. I tried to find thoes two files but failed. Can anyone advise?

I had this issue while trying to build ONNX locally within a virtualenv. Solved this way:

Be sure to have Cmake:

sudo snap install cmake --classic

Clone, build and install

1. Clone the repo:

git clone https://github.com/pybind/pybind11.git 
cd pybind11 
mkdir build 
cd build 

1. Set the python virtualenv you use with Onnx With pyenv: pyenv local 3.8.x
2. Build

cmake .. 
sudo make install

Pybind is installed for Python 3.8 in /usr/local/include/pybind11

Still an issue for me, as I’m not a conda user 😢
