# 安装 3.6.0 pyenv install --list pyenv 3.6.0 install -v # 使用搜狐镜像下载到 ~/.pyenv/cache中 v=3.5.2 wget http://mirrors.sohu.com/python/$v/Python-$v.tar.xz -P ~/.pyenv/cache/ pyenv install $v # 创建新的环境,位于 ~/.pyenv/versions/ pyenv virtualenv 3.6.0 env360 # 切换到新的环境 pyenv activate env360 # 退回到系统环境 pyenv deactivate # 删除新创建的环境 rm -rf ~/.pyenv/versions/env360/

安装自己的项目依赖

pip freeze > requirements.txt
pip install -r requirements.txt
scipy/pandas/ipython/jupyter/opencv-python/keras
pip install -U scikit-learn==

使用科大源

pip install <包名> -i http://pypi.mirrors.ustc.edu.cn/simple/ inux下，修改 ~/.pip/pip.conf (没有就创建一个)，修改 index-url至ustc 豆瓣和ustc的比较全，内容如下： [global] index-url = http://pypi.mirrors.ustc.edu.cn/simple/ [install] trusted-host = pypi.mirrors.ustc.edu.cn windows下，直接在user目录中创建一个pip目录，如：C:Usersxxpip，新建文件pip.ini，内容如下 [global] index-url = https://pypi.tuna.tsinghua.edu.cn/simple

安装jupyter
pip install jupyter

设置密码
from notebook.auth import passwd
passwd()

生成配置文件

jupyter notebook --generate-config

修改配置文件

vim ~/.jupyter/jupyter_notebook_config.py

c.NotebookApp.ip = '*'
c.NotebookApp.password = u'sha1:bcd259ccf...'
c.NotebookApp.open_browser = False
c.NotebookApp.port = 9999
c.NotebookApp.notebook_dir = '/home/xsy/code'
