1、安装CUDA、cuDNN、Anaconda、Tensorflow-GPU和pyTorch：
准备安装文件：
ubuntu@ubuntu:~$ ls anaconda3 NVIDIA-Linux-x86_64-440.31.run Anaconda3-5.1.0-Linux-x86_64.sh snap cuda_10.0.130_410.48_linux.run 公共的 cudnn_samples_v7 模板 Downloads 视频 examples.desktop 图片 libcudnn7_7.4.2.24-1+cuda10.0_amd64.deb 文档 libcudnn7-dev_7.4.2.24-1+cuda10.0_amd64.deb 下载 libcudnn7-doc_7.4.2.24-1+cuda10.0_amd64.deb 音乐 NVIDIA_CUDA-10.0_Samples 桌面
安装后用 nvidia-smi 查询GPU参数：
ubuntu@ubuntu:~$ nvidia-smi

安装后用 nvcc -V 查询CUDA版本：
ubuntu@ubuntu:~$ nvcc -V nvcc: NVIDIA (R) Cuda compiler driver Copyright (c) 2005-2018 NVIDIA Corporation Built on Sat_Aug_25_21:08:01_CDT_2018 Cuda compilation tools, release 10.0, V10.0.130

2、使用Anaconda创建虚拟环境：
查看已安装的虚拟环境：
conda info -e
指定Python版本创建虚拟环境：
conda create --name py36 python=3.6
查看虚拟环境安装过的依赖包：
conda list -n py36
给虚拟环境安装依赖包：
conda install -n py36 cudnn
激活虚拟环境：
source activate py36
退出虚拟环境：
source deactivate
给虚拟环境安装OpenCV-Python：
conda install -n py36 --channel https://conda.anaconda.org/menpo opencv3
