Installed Winpython , run Jupyter Notebook.exeor Jupyter lab.exealways not automatically open the browser, suggesting that "no web browser found"

A Solution

   c.NotebookApp.browser = u'D:/ProgramFiles/Browsers/Chrome75/MyChrome.exe %s'
4. Save changes.
5. Running Jupyter Notebook.exeor Jupyter lab.exealready automatically open the browser.

   #import webbrowser
   webbrowser.register("Chrome",None,webbrowser.GenericBrowser(u'D:/ProgramFiles/Browsers/Chrome75/MyChrome.exe))
   c.NotebookApp.browser = 'Chrome'

2. Save changes

note

• The above D:/ProgramFiles/Browsers/Chrome75/is chrome installation directory, I used Mychorm green.
• If you do not jupyter_notebook_config.py, you can run jupyter notebook --generate-config, it will automatically generate configuration files.
