Error launching notebook on Windows 7

[tjfulle]

Jupyter fails to open new notebooks on Windows 7 with a clean install of Anaconda (Python version 2.7). The notebook fails to launch with IPython 3.2 and IPython 4.0/Jupyter 1.0. The symptoms are:

• jupyter notebook server starts
• when creating a new Python 2 notebook, the resultant page displays a 404: page not found error.

I am using the Internet Explorer as a browser. I have had no issues on Mac OS X or Linux Mint.

A problem seems to be indicated in the console log:

The last line shows the 404 GET /undefined error. On another Windows machine (notebook launches fine), the line

... 200 GET /custom/custom.css 

read

... 304 GET /custom/custom.css

and before the

... 200 GET /api/kernelspecs (::1) 4.00ms

line it gives

... Native kernel (python2) available from ...
... Native kernel (python2) available from ...

I'm not sure if that is indicative or not.

[Carreau]

Can you try a ipython kernelspec install-self ? you shouldn't have to worry about the 304 and 404 you see.

[tjfulle]

Thanks for the quick response. The outcome is:

[myenv] C:\Apps\Python27_Anaconda> ipython kernelspec install-self
[InstallNativeKernelSpec] Installed kernelspec python2 in C:\ProgramData\jupyter\kernels\python2
[myenv] C:\Apps\Python27_Anaconda>

[Carreau]

And if you re-try to create a Python2 notebook now ?

[tjfulle]

If it helps, I see different behavior depending on where I execute ipython notebook. If in the default location for the Anaconda command prompt (C:\Apps\Python_Anaconda) I get the 404 page not found error - but Untitled.ipynb is created. If I navigate to other locations a blank page launches and no Untitled.ipynb.

[tjfulle]

Sorry, the ipython kernelspec install-self did not resolve the issue.

[Carreau]

Hum.... (thinking..)

[tjfulle]

I misspoke earlier - Untitled.ipynb is created whenever I create a new notebook, I just can't access it (either 404 page not found or just a blank screen).

As I mentioned, the notebook is working fine on another Windows 7 machine (nominally the same setup) and works like a charm on any of my *nix machines.

[tjfulle]

Carreau, we may have determined a problem. IT had set the "Start In" location of the IPython Notebook launcher that comes as part of the Anaconda package to be an admin location for testing and then pushed it to users (without changing the "Start In" location). Changing the "Start In" location to a path where users could write seems to have fixed things. I'm still confused because

• when creating a notebook from the dashboard (using the admin "Start In" location), the notebook was created but I could not open it
• I could not open notebooks if I launched the dashboard from the command line in my Documents directory
• using a virtual environment did not seem to help

Unless the notebook is inheriting the "Start In" location in some way, I'm not sure why it would affect each use case described.

I'm not sure if this is a user error, Anaconda, or notebook error. Feel free to close this issue or do with it what you see fit.

Thanks for all the hard work!

[KimDaeEon]

I have same problems now... Did you fix it? If you did.. Please let me know..

[a59]

I also have the same problem.

[KimDaeEon]

I formated my computer and solved it..
If you have installed another python or anaconda before and erase it not correctly.. you may have problems above.. I recommend to format your PC. That is fastest solution..

[a59]

Reformatting seems a bit drastic. Besides, I don't have admin priviledges on the computer.

[KimDaeEon]

Sad.. Cheer up..
