  ERROR: Failed building wheel for onnx

Question why ： The lack of Protobuf compiler
terms of settlement （ Install other dependencies ）：

sudo apt-get install -y libprotobuf-dev protobuf-compiler python3-scipy

notes ： To install scipy Proposed installation 1.4.1 edition , I suggest you refer to my last post ：jetson nano install tensorflow Record on pit (scipy1.4.1)

fatal error: Python.h: There is no file or directory

    By not providing "Findpybind11.cmake" in CMAKE_MODULE_PATH this project has
    asked CMake to find a package configuration file provided by "pybind11",
    but CMake did not find one.
  
    Could not find a package configuration file provided by "pybind11"

    Add the installation prefix of "pybind11" to CMAKE_PREFIX_PATH or set
    "pybind11_DIR" to a directory containing one of the above files.  If
    "pybind11" provides a separate development package or SDK, be sure it has

  ERROR: Failed building wheel for onnx
Failed to build onnx
ERROR: Could not build wheels for onnx which use PEP 517 and cannot be installed directly

The reason for the error ： No installation python3-dev
Try entering the command to install ：sudo apt-get install python3-dev
The following error occurred ：

 Some packages can't be installed . If you use  unstable  Distribution version , This may be 
 Because the system cannot reach the state you require . There may be some software you need in this release

 The following information may help solve the problem ：

 The following packages have unsatisfied dependencies ：
 python3-dev :  rely on : python3 (= 3.6.5-3)  however  3.6.7-1~18.04  It's about to be installed 
                rely on : libpython3-dev (= 3.6.5-3)  But it will not be installed 
                rely on : python3.6-dev (>= 3.6.5-2~)  But it will not be installed 
E:  Unable to fix error , Because you want some packages to be as they are , It's them that break the dependencies between packages .

terms of settlement ： Use aptitude install ：sudo aptitude install python3-dev
If not installed aptitude Install first ：sudo apt-get install aptitude

 The following “ new ” The package will be installed .

      keep   The current version of the package is ：

3)     python3-dev [ Not installed ]     
4)     python3.6-dev [ Not installed ]   
 Whether to accept the solution ？[Y/n/q/?]

choice y enter , Will maintain the original state . It cannot be installed here because there is a problem with the official source , Not updated with the latest python3-dev package .
I checked , Official main server python3-dev The latest version of only supports python3.6.5 Version of , But my jetson nano Own is python3.6.9. If you use aptitude Forcibly downgrade the installation , So your python3 The environment will collapse directly , Any module you import will appear ： Illegal order ( The core has been dumped ) Error of . So here's a reminder .
The solution I found is ： Switch domestic ubuntu Source （ Tutorial tips from Taobao merchants ： Switching domestic sources is risky , Other incompatibilities may occur , But I haven't found any sequelae yet ）：

deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ bionic main multiverse restricted universe

Update the software source after switching , Then you can install python3-dev 了 .
Once installed , continue installation onnx：
