TensorFlow : Install (GPU Support)2020/07/23
 
Install TensorFlow which is the Machine Learning Library.
On this example, Setup TensorFlow to use NVIDIA GPU on your computer.
This example is based on the build configurations like follows.
⇒ TensorFlow 2.2, CUDA 10.1, cuDNN 7.6, Python 3.8
You can see Tested build configurations on the site below.
⇒ https://www.tensorflow.org/install/source?hl=en#gpu_support_2
[1]
Install CUDA 10.1, refer to here.
[2]
Install Python 3.8, refer to here.
[3]
Download cuDNN (CUDA Deep Neural Network library) from the NVIDIA official site. (it needs to register a developer account)
⇒ https://developer.nvidia.com/rdp/cudnn-download
[4] Upload cuDNN to your Server and locate files like follows.
[root@dlp ~]#
tar zxvf cudnn-10.1-linux-x64-v7.6.5.32.tgz

[root@dlp ~]#
cp ./cuda/include/cudnn.h /usr/local/cuda-10.1/include/

[root@dlp ~]#
cp -a ./cuda/lib64/libcudnn* /usr/local/cuda-10.1/lib64/

[root@dlp ~]#
ldconfig

[root@dlp ~]#
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda-10.1/extras/CUPTI/lib64' >> /etc/profile.d/cuda101.sh

[root@dlp ~]#
source /etc/profile.d/cuda101.sh

[5] Install other required packages.
[root@dlp ~]#
dnf -y install python38-devel python3-virtualenv gcc gcc-c++ make
[6] Login as a common user and prepare Python virtual environment to install TensorFlow.
If you'd like to install it on System Wide, skip this section and execute the next [7] with root user account.
[cent@dlp ~]$
/usr/bin/py3-virtualenv --system-site-packages -p python3 ./venv
