Moving Python installation folder does not update ipython paths

问题 I moved my Python 2.7 installation from C:\Python to D:\Python by simply moving the folder (I understand there are other ways to do this). When running D:\Python\python.exe , I can import system libraries and run things without any issues. However, I cannot run D:\Python\Scripts\ipython.exe. I get the following error: Fatal error in launcher: Unable to create process using '"C:\Python\python.exe" "D:\Python\Scripts\ipython.exe" ' It seems that ipython is aware of its original installation

How to save state of ipython widgets in jupyter notebook using python code

由 岁酱吖の 提交于 2020-01-24 19:49:05
问题 I am using ipython widgets in my jupyter notebook. Now when kernel is restarted, the widget state is lost and a message is displayed: “Jupyter widget could not be displayed because the widget state could not be found. This could happen if the kernel storing the widget is no longer available, or if the widget state was not saved in the notebook. You may be able to create the widget by running the appropriate cells” So when a user reopens his notebook after a kernel restart, he doesn't find the

一.部署环境 　　系统：CentOS 6.4x64 最小化安装 　　IP:192.168.52.131 　　git默认使用SSH协议，在服务器上基本上不用怎么配置就能直接使用。但是如果面向团队服务，需要控制权限的话，还是用gitolite方便些。 　　首先用x-shell 工具链接centos 系统 二.安装基础依赖包 [root@nginx ~]#yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel perl-devel -y 三.在线安装git [root@bogon ~]# yum -y install git 下载安装包安装方式： [root@bogon git-2.2.0]#tar xf git-2.2.0.tar.gz [root@bogon git-2.2.0]#cd git-2.2.0/ [root@bogon git-2.2.0]#make prefix=/usr/local/git all [root@bogon git-2.2.0]#make prefix=/usr/local/git install 增加软连接 [root@bogon git-2.2.0]#ln -s /usr/local/git/bin/* /usr/bin/ 验证结果，显示出版本号，表示安装成功

pygal charts not displaying tooltips in Jupyter / IPython notebook

问题 After much research, I finally managed to get tooltips working in pygal thus: Config = pygal.Config() Config.js = ['http://kozea.github.io/pygal.js/2.0.x/pygal-tooltips.js'] bar_chart = pygal.Bar(Config) # Then create a bar graph object bar_chart.add('Fibonacci', [0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55]) # Add some values bar_chart.render_to_file('bar_chart.svg', force_uri_protocol='https') In the produced .svg, tooltips are now working nicely, but only when the file is opened in a browser .

Using multiple Python shells in Emacs 'python-mode' with Python or IPython

由 余生颓废 提交于 2020-01-22 15:14:25
问题 Is there a way to force a new instance of python-shell while running Emacs? It would be convenient when working on multiple projects with separate working directories (and different sets of modules).

Use M - x rename-buffer . 回答2: Renaming the buffer doesn't work for me, but you can use the third parameter of run-python . M - : (run-python
