"Kernel is not ready!" with Ipython 1.0.0

emase commented 11 years ago

Check list

[* ] I read "Avoid standard Emacs traps" section in https://github.com/tkf/emacs-ipython-notebook/blob/master/CONTRIBUTING.md
[* ] I checked that IPython works with the browser interface.
[* ] I checked that the problem was not due to badly compiled files. Removing *.elc files from source directory of EIN and its dependencies did not solve the problem.
[* ] I checked that the libraries are loaded from intended place. (You can check the location in the "System info" section below)
Description of the problem you have

When I try executing code from a cell, I get the error: ein: [warn] Kernel is not ready yet! (or closed already.)

Everything was fine until I upgraded my ipython from 0.13.1 to 1.0.0

Downgrading ipython from 1.0.0 to 0.13.2 and things work fine. I guess something changed at 1.0.0

Steps to reproduce the problem

Run emacs. Open notebooklist. Open a new notebook
Type print "hello" and then select execute-cell
Expected output

"hello"

Your EIN configuration (in .emacs.d/init.el or somewhere else)

no idea

Your IPython configuration

What is your IPython version? (run ipython --version): $ ipython --version 1.0.0
How do you start IPython? (e.g., ipython notebook --port 9999): ipython notebook --profile=nbserver
What is your IPython notebook port number or URL?: http://ghettosuperstar:8888
Additional information (if any)

Upgraded ipython from 0.13.1 to 1.0.0 using pip install --upgrade ipython Tried running ein to connect and received "Kernel is not ready yet!" error. Used M-x package-list-package to update EIN and its dependencies. Still get "Kernel is not ready yet!"

Please wait for a while. See #131.

Just wanted to confirm that I too am experiencing the same issue.

Thanks for EIN!

ethanwhite commented 10 years ago

The examples given here are working fine for me with IPython 1.1.0, Emacs 24.3.1, Ubuntu 13.10. It might be worth trying upgrading IPython again in case something was fixed/changed back in 1.1.

emase commented 10 years ago

Hmm... still getting the same error after upgrading.Upgraded setup: emacs 24.3.1 (with a clean MELPA install of ein) on Windows 7ipython 1.1 on Ubuntu 12.04 Originally was using emacs 24.2, but will keep 24.3.1 now that I have it setup. Both versions of emacs work correctly with ipython 0.13.2, but not with 1.0 or 1.1

ethanwhite commented 10 years ago

Hmm... only differences seem to be Ubuntu version (unlikely) and that I installed EIN using el-get, not MELPA. I just checked this on another machine with the same setup and EIN is working there as well (at least the basic stuff).

Hi Takafumi,

Thanks for writing ein. It's really impressive, and I'd like to make it a permanent part of my workflow. I'm having the same problem here. I saw issue #131 and understand that it's on the backburner :), so I'm including this bug report only because it seems like there's some uncertainty about exactly which conditions trigger this bug. Perhaps another data point might be useful.

cheers, Pat.
