Detailed process - install and start Jupyter notebook

1. Installation

Note : I did n't install Anaconda , and I felt that I needed the tool Jupyter notebook halfway, so I passed it in windowscmd command windowDownload, install and use.

*step1:*Switch path

(If you have not added the Python installation directory to Path, you need to switch to the Scripts directory of the Python installation directory) The details are as follows:

*step2:*Download

Enter pip install jupyter

and wait for the installation to complete~~~

Some may report an error, then switch to the domestic mirror download

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

*step3:*Start Juypter Notebook

Enter in the command window: jupyter notebook The computer browser automatically opens the Jupyter Notebook window as follows, indicating that the installation is successful:

*step4:*Configure Jupyter Notebook

Enter in the CMD command window and jupyter notebook --generate-config

you can see that the user folder has a .jupyter file. Open the configuration file jupyter_notebook_config.py and


find the statement c.NotebookApp.notebook_dir = ' ', and modify it to c.NotebookApp.notebook_dir = 'store jupyter notebook The folder path of the code written in'

Note: delete the preceding #! ! !
If it has not yet taken effect, you can use a shortcut:

then right-click the shortcut button, modify the properties of the shortcut button, and change the starting location to the path location you need to store

step5 (optional): Add code auto-completion function

1. Enter pip install jupyter_contrib_nbextensions in the cmd command window, and wait for the installation to succeed~~~
   
   If you encounter a timeout problem, switch to the domestic image download
   pip install jupyter_contrib_nbextensions -i https://pypi.tuna.tsinghua.edu.cn/simple/

2. After installation, configure nbextension, enter jupyter contrib nbextension install --user --skip-running-check in cmd, and wait for the configuration to succeed~~~(Be careful to close the jupyter notebook first）

3. Then start jupyter notebook, click the option of Nbextension, and check Hinterland to add the code auto-completion function.
