TensorFlow : Install2024/06/21

	Install TensorFlow which is the Machine Learning Library. Set up TensorFlow to use the NVIDIA GPU installed in it.
[1]	Install CUDA, refer to here.
[2]	Install Python 3, refer to here.
[3]	Install cuDNN (CUDA Deep Neural Network library) and other required packages.

root@dlp:~#

apt -y install nvidia-cudnn python3-pip python3-dev gcc g++ make

[4]	Login as a common user and prepare Python virtual environment to install TensorFlow.

ubuntu@dlp:~$

python3 -m venv --system-site-packages ~/tensorflow

ubuntu@dlp:~$

source ~/tensorflow/bin/activate
