Don't change the computer easily , Don't change the computer easily , Don't change the computer easily ！！！

Important things are to be repeated for 3 times , Unless you have to .

First jupyter notebook It's a kind of Web application , stay jupyter Write code in Chinese and traditional IDE( Integrated development environment ) Such as pycharm comparison , Visualization is more convenient , meanwhile jupyter It also integrates the function of document notes , Easy to publish on the Internet . I believe my friends have used it .

jupyter notebook Installation , It can be installed separately jupyter, besides , In the installation anaconda I'll bring it directly when I get there jupyter notebook, Recommended by anaconda The way , Install directly together , After all, they are all for use .

Installation is not described in detail here , There are many blogs about this ：

If you don't make any settings , Open it directly jupyter, So congratulations , The picture is so ugly , And there is no one who can automatically complete god horse ……

Please press the following code in your base Operating in the environment ：

#  Replace the topic 
pip install jupyterthemes

#  Configuration scheme

With these , Opening the interface again is much more pleasing to the eye

  Next, let's talk about the configuration environment ：

If your jupyter notebook Encounter the same situation as me , After opening , stay new Can't find the desired development environment , Only python3 One option , Then please remember the following line of code , Run it once in every environment ：

#  Add kernels
conda install nb_conda_kernels
