//--------------------------------------
conda配置安装pytorch
1、新建环境，避免与基础环境出现冲突
conda create -n pytorch_gpu python=3.7
2、切换到pytorch环境
conda activate pytorch_gpu
3、安装基本框架
conda install pandas
conda install jupyter notebook
......
conda install pytorch torchvision cudatoolkit=10.1
//-------------------------------------
利用conda安装指定版本的tensorflow
conda install --channel https://conda.anaconda.org/anaconda tensorflow=1.6.0
conda install pytorch torchvision cudatoolkit=10.1 -c pytorch
conda install --channel https://conda.anaconda.org/anaconda tensorflow=1.8.0
