win10 下通过Anaconda 安装keras,pytorch,jupyter notebook (CPU版)

环境准备

Anaconda3-5.3.0-Windows-x86_64 (PYTHON 3.7)

安装

分别创建3个环境

conda create -n jupyter python=3.6 作为jupyter notebook启动的默认环境，安装scikitlearn等机器学习库

conda create -n pytorch python=3.7 pytorch 使用，安装fastai

conda create -n keras python=3.6 keras和tensorflow

#使用cpu版本可以直接使用conda安装，版本1.9.0，最近版1.11.0
conda install keras
#安装ipykernel
conda install ipykernel
#写入环境
python -m ipykernel install --user --name keras --display-name "keras with tensorflow"

#pytorch官网支持conda直接安装
conda install pytorch-cpu -c pytorch
pip3 install torchvision
#安装ipykernel
conda install ipykernel
#写入环境
python -m ipykernel install --user --name pytorch --display-name "pytorch with fastai"

打开Anaconda Navigator 在jupyter中安装jupyter book，然后打开可以看到两个新建的环境，启动即可

删除环境

1
conda env remove -n [环境名]

配置jupyter book

activate jupyter
jupyter notebook --generate-config
## 这里会显示创建jupyter_notebook_config.py的具体位置

打开文件，修改

c.NotebookApp.notebook_dir = '' #默认目录位置
c.NotebookApp.iopub_data_rate_limit = 100000000 # 这个改大一些否则有可能报错
