1. Building python3.9

$ sudo apt install zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev libbz2-dev

$ wget https://www.python.org/ftp/python/3.9.1/Python-3.9.1.tar.xz

$ tar xvf Python-3.9.1.tar.xz Python-3.9.1/

$ mkdir build-python-3.9.1

$ cd build-python-3.9.1/

$ ../Python-3.9.1/configure --enable-optimizations

$ make -j $(nproc)

$ sudo -H make altinstall

$ cd ../

2. Build cmake 3.13.5

$ sudo apt-get install -y protobuf-compiler libprotobuf-dev openssl libssl-dev libcurl4-openssl-dev

$ wget https://github.com/Kitware/CMake/releases/download/v3.13.5/cmake-3.13.5.tar.gz

$ tar xvf cmake-3.13.5.tar.gz

$ rm cmake-3.13.5.tar.gz

$ cd cmake-3.13.5/

$ ./bootstrap --system-curl

$ make -j$(nproc)

$ echo 'export PATH='${PWD}'/bin/:$PATH' >> ~/.bashrc

$ source ~/.bashrc

$ cd ../

3. Prepare header

$ mkdir python3.9

$ mkdir python3.9/include

$ wget http://ftp.us.debian.org/debian/pool/main/p/python3.9/libpython3.9-dev_3.9.9-2_arm64.deb

$ ar x libpython3.9-dev_3.9.9-2_arm64.deb

$ tar -xvf data.tar.xz

$ cp ./usr/include/aarch64-linux-gnu/python3.9/pyconfig.h python3.9/include/

$ cp -r Python-3.9.1/Include/* python3.9/include/

4. Build TensorRT pybinding

$ git clone https://github.com/pybind/pybind11.git

$ git clone -b release/8.0 https://github.com/NVIDIA/TensorRT.git

$ cd TensorRT

$ git submodule update --init --recursive

Please replay {TensorRT}/python/build.sh with this file: build.sh (2.5 KB)

build.sh-->https://forums.developer.nvidia.com/uploads/short-url/oOBhYDgezhZl6IIuoIXSTRiZbuj.sh

注意build.sh中python版本，如果本地的是python3.9，则将build.sh中python改成python3.9

$ cd python/

$ TRT_OSSPATH=${PWD}/.. EXT_PATH=${PWD}/../.. ./build.sh

$ python3.9 -m pip install build/dist/tensorrt-8.0.1.6-cp39-none-linux_aarch64.whl
