jupyter giving 404: Not Found error on WIndows 7

jupyter notebook 404 : not found you are requesting a page that does not exist!
jupyter notebook python 3 kernel error

jupyter notebook not opening in browser

jupyter notebook not found

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 windows using

jupyter notebook

it launches on Firefox and states

404: Not Found

On the command it says

Refusing to serve hidden directory via 404 Error

What needs to be done to get it launched?

Update: The anaconda install has a shortcut to run jupyter and it works that way - but gives 404 for "jupyter notebook":

d:\Anaconda\Scripts/ipython-script.py" notebook

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.

Jupyter notebook, It gives me error: 404 : Not Found You are requesting a page that does not exist! But I can run it from Anaconda Prompt. How fix it? 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 windows using jupyter

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

Hi, I am an Anaconda newbie. (Previously did some very basic Python 2.7 computing using Idle.) I installed Anaconda with Python 2.7.10 on my Windows 7 laptop following recommended settings.

A 404 error is an HTTP status code that means that the page you were trying to reach on a website couldn't be found on their server. To be clear, the 404 error indicates that while the server itself is reachable, the specific page showing the error is not. 404 Not Found error messages are frequently customized by individual websites.

Comments
  • Hello I am currently on windows 7. To solve the problem i set google chrome as my default browser. It worked just fine.
  • Strangely I had this problem with Anaconda but not Winpython distribution. With anaconda, you should not be on a root of a drive.
  • I had the same problem running Jupyter with Anaconda.
  • this solved my problem as well, created a new directory in D: drive and followed this tutorial -> technivore.org/posts/2016/02/27/windows-jupyter-three-ways.html
  • How is it hidden? I launched it from D dir - Anaconda is in d:\Anaconda\ - Which one is a non-hidden dir?
  • Well I got it working now by changing dir - how can I set path? Path D:\Anaconda\Scripts\ was added on install?
  • Please post your answer or check the right existing answer.
  • Worked for me :)
