一、jupter切换环境

二、卸载jupyter

pip uninstall -y jupyter
pip uninstall -y jupyter_core
pip uninstall -y jupyter-client
pip uninstall -y jupyter-console
pip uninstall -y notebook
pip uninstall -y qtconsole
pip uninstall -y nbconvert
pip uninstall -y nbformat
pip uninstall -y jupyter-packaging
pip uninstall -y jupyter-server
pip uninstall -y jupyterlab
pip uninstall -y jupyterlab-pygments
pip uninstall -y jupyter-console
pip uninstall -y jupyterlab-server
pip uninstall -y jupyterlab-widgets

三、jupyter扩展的安装

#1.安装
conda install -c conda-forge jupyter_contrib_nbextensions
#或者
pip install jupyter_contrib_nbextensions
#2.设置
jupyter contrib nbextension install --user

四、jupyter notebook显示的扩展很少，只有四五个–解决方案

conda remove jupyter_nbextensions_configurator
conda install -c conda-forge jupyter_nbextensions_configurator
conda install -c conda-forge jupyter_contrib_nbextensions

五、启动jupyter notebook

python -m notebook
Jupyter notebook

六、jupter打开网页没进入编程页面

Anaconda Prompt (ANaconda 3)中先激活环境activate jupter_huan，再输入jupyter notebook

七、卸载并重新安装jupyter

1.conda create -n p0 python=3.8
conda activate p0
2.conda install ipykernel
3.python -m ipykernel install --user --name p0 --display-name “pytorch3.7"
4.conda deactivate
//打开jupyter notebook
jupyter notebook

八、jupyter notebook使用新环境

1.conda create -n p0 python=3.8
conda activate p0
2.conda install ipykernel
3.python -m ipykernel install --user --name p0 --display-name “pytorch3.7"
4.conda deactivate
//打开jupyter notebook
jupyter notebook

九、jupyter需要密码

jupyter notebook --generate-config
将：jupyter_notebook_config.py文件中的c.NotebookApp.password后面的密码删掉，如下：
c.NotebookApp.password = ‘’

将jupyter_notebook_config.json文件中的"password"后面的密码删掉，如下：
“password”: “”

十、jupyter更改路径

管理员身份打开Anaconda prompt输入：jupyter notebook --generate-config
文件夹路径C:\Users\Administrator.jupyter
c.NotebookApp.notebook_dir = u’D:\Program Files\jupyter’
如果没有，就直接在文件末尾输入这句话，且不加#
