关于jupyter notebook使用过程中的一些排错

1：使用jupyter notebook不能中断正在运行的程序
解决办法：打开conda Promet进入自己的环境，输入pip3 install --upgrade --force-reinstall --no-cache-dir jupyter这句话，在运行这句话的过程中可能会出现这样的报错信息。

ERROR: Cannot uninstall 'ipython-genutils'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

此时，要寻找到ipython-5.1.0-py3.6.egg-info这个文件（中间的版本号可能不同，主要是ipython-*-*-*-***.egg-info这种格式），此文件的位置在你环境文件中，类似于D:\Anaconda\envs\keras_gpu\Lib\site-packages\ipython-*-*-*-***.egg-info，找到这个文件之后删除，再运行第一句话即可。此时还可能报错，

ERROR: Could not install packages due to an EnvironmentError: [WinError 5] 拒绝访问。: 'd:\\anaconda\\envs\\keras_gpu\\lib\\site-packages\\_cffi_backend.cp37-win_amd64.pyd'
Consider using the `--user` option or check the permissions

根据报错信息，此时应该运行这句pip3 install --upgrade --force-reinstall --no-cache-dir jupyter --user，之后会有一堆warning和error出现，

WARNING: The script jupyter-console.exe is installed in 'C:\Users\Admin\AppData\Roaming\Python\Python37\Scripts' which is not on PATH.
  Consider adding this directory to PATH or, if you prefer to suppress this warning, use --no-warn-script-location.
ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

我选择添加了系统变量，不添加似乎也没事。到此，程序不能中断的问题解决了，但是出现的这些报错不知道怎么解决。
