ipython from windows command line

Question

I changed the environment variable PATH, to a new value and then back to what I believe was the original one. But now I can't open a .ipynb file through the Windows command line the was I was used to.

After changing the directory in command line and running

ipython notebook notebook_name.ipynb

I get the following message:

'ipython' is not recognized as an internal or external command.

My environment variable is set to a folder with python.exe, and this folder includes a subfolder with ipython.exe and jupyter-notebook.exe. When I open iPython command line and type %env, I can see the full path to the correct subfolder under PATH.

Can someone point to a solution?

Thanks.

So I figured out a solution - I changed the environment variable PATH to the subfolder with the .exe files. Although the path including this subfolder was listed under %env, it did not work without being referred directly in the System setting.

Looks like you figured out that you have to set the extension association in System Settings.

I've found that I'm using Notebooks often enough that it was well worth using AutoHotKey with the following script to open the Jupyter Notebook server in my default directory (or the currently highlighted directory in Explorer)

#SingleInstance Force
#NoTrayIcon

SetTitleMatchMode RegEx

; Press CTRL+ALT+I in a Windows Explorer window to launch a IPython notebook server in the current folder.
^+!i::
; Get the current path.
Send ^l
; Backup the current clipboard.
ClipSaved := ClipboardAll
; Copy and save the current path.
Send ^c
ClipWait
x = %Clipboard%
; Restore the clipboard.
Clipboard := ClipSaved
ClipSaved = ; Free the memory in case the clipboard was very large.
; Now, run the IPython notebook server.
RunWait, ipython notebook --notebook-dir "%x%", , min
return

^i::
; Now, run the IPython notebook server.
RunWait, jupyter notebook --notebook-dir "C:\Path\To\WorkSpace", , min
return

; Press CTRL+ALT+P to kill all Python processes.
^!p::
Run, taskkill /f /im python.exe, , min
return
