1、pip3方式安装tensorflow-gpu
官方文件地址为：
https://developer.nvidia.com/embedded/downloads#?search=TensorFlow

url为：https://developer.download.nvidia.com/compute/redist/jp/v42/tensorflow-gpu/tensorflow_gpu-1.13.1+nv19.4-cp36-cp36m-linux_aarch64.whl
安装基础必备的包
sudo apt-get install python3-numpy #不知道numpy是干啥的？机器学习这个领域不适合你
sudo apt-get install python3-scipy
sudo apt-get install python3-pandas
sudo apt-get install python3-matplotlib
sudo apt-get install python3-sklearn
sudo apt-get install libhdf5-serial-dev hdf5-tools
安装脚本
pip3 install --extra-index-url https://developer.download.nvidia.com/compute/redist/jp/v42 tensorflow-gpu==1.13.1+nv19.4 --user
执行如下：(需要下载的依赖组件比较多，时间较长)

2、测试tensorflow-gpu
简单demo看能否跑的起来
import tensorflow as tf
hello = tf.constant('Hello, TensorFlow!')
sess = tf.Session()
print(sess.run(hello))
出现numpy错误
>>> import tensorflow as tf
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
ImportError: numpy.core.multiarray failed to import
ImportError: numpy.core.umath failed to import
ImportError: numpy.core.umath failed to import

Aborted (core dumped)
解决方法如下，numpy版本不匹配；
https://github.com/enigmampc/catalyst/issues/106
pip3 install -U numpy==1.14.1
运行效果
