Record of pychart running jupyter notebook in virtual environment

The following is bullshit , Just install one package

pip install ipykernel  

pycharm Prompt you whether to register this project into kernel

 

----------------------------------- Split line ---------------------------------

 

 

 

One 、 Recently pycharm Running in ipynb File found a problem , If you are in a virtual environment venv There will be a prompt in the ：jupyter kernel does not match project interpreter

Prompt kernel version mismatch , requirement register project interpreter as kernel, Prompt if selected dll Problem module not found

In fact, at this time jupyter It has been started , And can be accessed on the web , Guess it is pycharm The problem of identification

I install it repeatedly tornado package 【 Just trying to uninstall and reinstall casually solves this problem , Install after missing package pycharm Will reboot and start the process 】

pip install 'tornado==6.1' --force-reinstall

#  perhaps 

pip uninstall tornado
&&
pip install tornado

 

Two 、 If it's in conda In the virtual environment of jupyter notebook Words , Find out pycharm Show jupyer notebook Only system python3 Environmental Science

1. install ipykernel

pip install ipykernel  

2. Write environment to notebook Of kernel in ,

python -m ipykernel install --user --name your_env_name --display-name your_env_name 

 give an example ： My environment name is  jupy

python -m ipykernel install --user --name jupy --display-name 'Python(jupy)'

See the effect ：kernel Switched

 

 

3、 ... and 、 One last sentence , If you want to in base conda Of notebook Switch environment in , need pip install nb_conda, It can be opened jupyter I see in the document change kernel The item

 Delete... In addition kernel Environmental Science ：

jupyter kernelspec remove  Name of the environment 

 see kernel list 

jupyter kernelspec list
