ubuntu16.04安裝cuda10.1、cudnn7.6、tensorflow2.2

（1）參考tensorflow官網給出的示例：https://www.tensorflow.org/install/gpu

# Add NVIDIA package repositories
# Add HTTPS support for apt-key
sudo apt-get install gnupg-curl
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/cuda-repo-ubuntu1604_10.1.243-1_amd64.deb
sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1604/x86_64/7fa2af80.pub
sudo dpkg -i cuda-repo-ubuntu1604_10.1.243-1_amd64.deb
sudo apt-get update
wget http://developer.download.nvidia.com/compute/machine-learning/repos/ubuntu1604/x86_64/nvidia-machine-learning-repo-ubuntu1604_1.0.0-1_amd64.deb
sudo apt install ./nvidia-machine-learning-repo-ubuntu1604_1.0.0-1_amd64.deb
sudo apt-get update

# Install NVIDIA driver
# Issue with driver install requires creating /usr/lib/nvidia
sudo mkdir /usr/lib/nvidia
sudo apt-get install --no-install-recommends nvidia-418
# Reboot. Check that GPUs are visible using the command: nvidia-smi

# Install development and runtime libraries (~4GB)
sudo apt-get install --no-install-recommends \
    cuda-10-1 \
    libcudnn7=7.6.4.38-1+cuda10.1  \
    libcudnn7-dev=7.6.4.38-1+cuda10.1


# Install TensorRT. Requires that libcudnn7 is installed above.
sudo apt-get install -y --no-install-recommends \
    libnvinfer6=6.0.1-1+cuda10.1 \
    libnvinfer-dev=6.0.1-1+cuda10.1 \
    libnvinfer-plugin6=6.0.1-1+cuda10.1

（2）配置環境變量

# 打開配置文件
vi ~/.bashrc
# 也可以使用
gedit ~/.bashrc

#導入下面語句
export PATH=/usr/local/cuda/bin:${PATH:+:${PATH}}
export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/extras/CUPTI/lib64

（3）請注意這一句

sudo apt-get install --no-install-recommends nvidia-418

（4）安裝tensorflow2.2，集成了cpu和gpu版本，無需單獨安裝cpu或者gpu版本

pip install tensorflow

（5）運行python程序，測試tensorflow是否使用gpu，如果沒有使用gpu，那麼請注意我們之前安裝的語句

sudo apt-get install --no-install-recommends nvidia-418

（6）查看運行python程序時，會報錯 nvidia driver 418和450（我的是這個錯誤）不匹配

（7）這時我們只需要安裝對應的那個高的版本就可以了

sudo apt-get install --no-install-recommends nvidia-450

（8）錯誤不盡相同，這裏僅供參考
