之前一直用pycharm,今天把code升级到1.3.2的时候, 突然提示我安装python扩展,决定试试。 结果发现python的解释器设置有问题, 总是设置为系统的解释器, 而虚拟环境的解释器不起作用。 apt remove --purge python3.5 reboot 结果ubuntu桌面启动不了。好多应用程序例如chrome,virtualbox都消失了, 造成了很大的麻烦。 Ctrl+Alt+F1进入虚拟控制台登录 apt install python3.5 apt install ubuntu-desktop 重新安装chrome和virtualbox cd /etc/apt/sources.list.d sudo mv google-chrome.list apt update apt install google-chrome-stable

entry into jupyter notebook

generate configuration file $jupyter notebook --generate-config Writing default config to: /home/bigo/.jupyter/ $ diff c.NotebookApp.allow_remote_access = True c.NotebookApp.ip = '' c.NotebookApp.open_browser = False set or reset password $jupyter notebook password Enter password: Verify password: [NotebookPasswordApp] Wrote hashed password to /home/bigo/.jupyter/jupyter_notebook_config.json then restart notebook server Sharing notebooks When people talk of sharing their notebooks, there are generally two paradigms they may be considering. Most often, individuals share the end-result of their work which means sharing non-interactive, pre-rendered versions of their notebooks; however, it is also possible to collaborate on notebooks with the aid version control systems such as Git
