Jupyter Giving 404: Not Found Error On Windows 7

June 12, 2024 Post a Comment

I installed anaconda PYTHON 2.7 64bit on Win 7 and then updated using conda update conda Later installed conda install jupyter When I tried to run from the same drive on window

Solution 1:

I found a simple cause of this could be trying to run Jupyter from the root of a drive - running it from C:\ failed. Cricboy007's suggestion to create a folder (no particular name, I called mine notebook) and run Jupyter once you've used cd to make that the working directory worked for me.

Solution 2:

I was having the same 404 error and solved it by doing the following:

right click the jupyter notbook shortcut > properties > change the value of "Start in:" to a path within your Anaconda install (e.g., D:\Anaconda2\Notebooks).

If you are running from the command line, changing directory to within the anaconda folder should work too

Solution 3:

Well as it says it refuses to serve a hidden directory. Try launching it from a non-hidden directory.

Solution 4:

Manually change the directory to Anaconda2. eg. cd Anaconda2 then run - jupyter notebook

Solution 5:

I meet this case.when I try to open jupyterlab,Anaconda tells me this:

and chrome shows 404:Not Found.when I open the jupyter in anaconda,I also meet case like that. so I update jupyterlab and jupyter,then all become good.Therefore,this case might be version problem.
