The installation environment is really troublesome. Third-party tools have the advantage, that is, free installation. The disadvantage is that if you don’t know it, there are many detours when you don’t understand it.
Fortunately, I learned the cmd command and understood its tools. Thanks to friends on the Internet for their summary. Although the road is curved, my heart is really straight.
Everyone has a different perspective and a different learning perspective. Long live understanding and long live practice!

1. Whether the network card of the machine is installed, use nvidia-smi this command, sometimes the path is different, this should pay attention to

Only care about the main points. NVIDIA-SMI 456.71 Driver Version: 456.71 CUDA Version: 11.1
2. View the CUDA version. Because it needs to match with other versions (cudnn tenslorflow), use pen records. Or familiar with it over and over again
C:\Users\PC>nvcc -V
nvcc: NVIDIA (R) Cuda compiler driver

Three, Anaconda3-2019.10-Windows-x86_64.exe installation
selects the automatic setting of system variables.
Four, update conda to the latest version: conda update -n base conda to
check the conda version: conda -V
and then execute: conda update --all
5. Install python specifies its installation path, please remember its path
conda create --prefix=D:\python37\py36 python=3.7
六、 conda install tensorflow-gpu
Seven, python -m site python installation has different paths, I am not sure about the specifics, use this command to view
eight, the current python path
where python
nine, whether python is installed successfully
python run test, or python --version
ten, configure pythcharm surroundings
11. Test the code, run
import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2'
import tensorflow as tf
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '2' # Do not display prompt messages below level 2
print('GPU', tf.config.list_physical_devices('GPU'))
a = tf.constant(2.0)
b = tf.constant(4.0)
print(a + b)
Twelve,
