在Python虚拟环境下开启jupyter notebook

安装并配置

第一步：安装Jupyter Notebook

pip install jupyter

第二步：进入你的 Virtualenv里 (我是的venv3)

source venv3/bin/activite

第三步：使用清华镜像安装 IPykernel，比较快

pip install -i https://pypi.tuna.tsinghua.edu.cn/simple ipykernel

第四步：将你的 Virtualenv 加入IPykernel里

python -m ipykernel install --user --name=venv3

第五步：打开Jupyter

jupyter notebook

报错以及处理

报错1：

[W 00:19:00.741 NotebookApp] No web browser found: could not locate runnable browser. 处理方式：

ipython from IPython.lib import passwd passwd() #得到加密后的hash exit jupyter notebook --generate-config vim ~/.jupyter/jupyter_notebook_config.py c.NotebookApp.ip = '*' c.NotebookApp.allow_root = True c.NotebookApp.open_browser = False c.NotebookApp.port = 8888 c.NotebookApp.password = u'sha1:...' #输入上面加密后得到的密文

报错2

Refusing to serve hidden directory, via 404 Error 如果成功在浏览器连接上服务器，但是登录输入密码后出现了404 You are requesting a page that does not exist!： 处理方式：在配置文件里面加上ipython文件的的保存路径就可以了（最后一行）

vim ~/.jupyter/jupyter_notebook_config.py c.NotebookApp.ip = '*' c.NotebookApp.allow_root = True c.NotebookApp.open_browser = False c.NotebookApp.port = 8888 c.NotebookApp.password = u'sha1:...' #输入上面加密后得到的密文 c.NotebookApp.notebook_dir = '/path/to/your/hidden/directory/'

报错3：登陆失败，则有可能是服务器防火墙设置的问题，此时最简单的方法是在本地建立一个ssh通道：

在本地终端中输入ssh username@address_of_remote -L127.0.0.1:1234:127.0.0.1:8888 此处的8888是指远程服务器jupyter登录的端口 便可以在localhost:1234直接访问远程的jupyter了。

报错4：

KeyError: 'allow_remote_access' During handling of the above exception, another exception occurred: ... Traceback (most recent call last): File "/home/yujwang/kou/venv3.5/lib/python3.5/site-packages/notebook/notebookapp.py", line 869, in _default_allow_remote addr = ipaddress.ip_address(self.ip) File "/usr/lib/python3.5/ipaddress.py", line 54, in ip_address address) ValueError: '' does not appear to be an IPv4 or IPv6 address During handling of the above exception, another exception occurred: ... socket.gaierror: [Errno -2] Name or service not known

在配置文件中加这样一行：

c.NotebookApp.allow_remote_access = True
