python环境配置
一、安装anaconda
1.清华镜像下载anaconda。下载64位的,之前下载32位的出现安装pytorch找不到包

2.notebook新增kernel
conda activate 环境名==============》conda install ipykernel===============》python -m ipykernel install --user --name tfenv --display-name "TFENV"
二、包安装
1.添加清华镜像源
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/ conda config --set show_channel_urls yes
2.恢复默认源
conda config --remove-key channels
3.下载pytorch
cpu版本的,一定要加cpuonly,不然会下载gpu版本的
conda install pytorch torchvision cpuonly -c pytorch
4.安装tensorflow
(原环境安装不了)
(1)重新创建环境
conda create --name tf15 python=3.7.3
(2)激活环境
conda activate tf15
(3)下载tensorflow
conda install tensorflow=1.15.0
(4)离开环境
conda deactivate
5.安装sklearn
conda install scikit-learn
6.安装ac自动机
conda install -c https://conda.anaconda.org/conda-forge pyahocorasick
