Subject: bug#18052: 24.3; python.el and ipython shell
Date: Fri, 18 Jul 2014 15:51:47 +0200 [thread overview]
Message-ID: <CAKrPhPOS8QvW87-Th3Nq=YwbRZLUMNYfcSdULb4JMmo9a=AjYw@mail.gmail.com> (raw)
I'm trying to use the ipython shell from within emacs. To do so I've
followed the instructions at the top of python.el and added the
following code to my .emacs:
(setq
python-shell-interpreter "C:/Anaconda/python.exe"
python-shell-interpreter-args
"-i C:/Anaconda/Scripts/ipython-script.py console --matplotlib=qt"
python-shell-prompt-regexp "In \\[[0-9]+\\]: "
python-shell-prompt-output-regexp "Out\\[[0-9]+\\]: "
python-shell-completion-setup-code
"from IPython.core.completerlib import module_completion"
python-shell-completion-module-string-code
"';'.join(module_completion('''%s'''))\n"
python-shell-completion-string-code
"';'.join(get_ipython().Completer.all_completions('''%s'''))\n")
When I execute (M-x) run-python, SOMETIMES the session does not
initialize properly and the new buffer looks like this:
-----------------------------------------------------------
Python 2.7.6 |Anaconda 2.0.1 (64-bit)| (default, Nov 11 2013,
10:49:15) [MSC v.1500 64 bit (AMD64)]
Type "copyright", "credits" or "license" for more information.

In [1]:
-----------------------------------------------------------
The difference compared to the situation when everything is well, is
that here I only see "In [1]:", while normally I should see 4 empty
input prompts, with the last one reading "In [4]". When I execute any
command such as "1+1" and press RET, nothing happens.
This happens starting emacs with the -Q option and executing the ipython
customization in the *scratch* buffer.
By running the debugger I've found out that emacs sends some commands to
the inferior python shell with (comint-send-string ...) and tries to
hide them from the user. That appears to be the reason for the four
empty prompts.
Looking at the running processes I've noted that there are 2 python
processes running. The task manager reports one as:
c:\Anaconda\python.exe -c"from IPython.kernel.zmq.kernelapp import main;
main()" -f
C:\Users\beffa\.ipython\profile_default\security\kernel-976.json
--matplotlib=qt --IPKernelApp.parent_appname='ipython-console'
--interrupt=692 --parent=696
(Obviously the value of the last two arguments change everytime.)
If I kill this process, the inferior python shell asks:
"kernel died, restart ([y]/n)? kernel died, restart ([y]/n)? kernel
died, restart ([y]/n)?"
If I press y the process is restarted and the inferior python shell
works fine (or at least responds to the commands like 1+1 that I've
tried).
I would greatly appreciate any suggestion on how to further dig into
debugging and solve this intermittent problem.
Thank you in advance for your help.
