When IPython renders tables, convert these to org tables. Outputting a data frame for example would be nice to get an org table.

It would be great to be able to utilize an ipython install from a virtualenv.

Just found ob-ipython and I'm thrilled to see improved IPython support in Org.

I'm working my way through the README and most things work as expected, but not the image example. The #+RESULTS: line shows a link to whatever filename I enter in the :file foo.png header command. But the file does not appear on disk nor does it display in the Org buffer.

I'm on OS X 10.10.3 and using a recent emacs from Homebrew.

Just add + '.json' there :
cf = find_connection_file('emacs-' + name)
and it works.

Hi,
I am running emacs on mac os. I have org mode installed and I am using python and ipython from mac ports. I added the relevant path to my .emacs file. I can also execute python code in org mode. However, I get the following message when trying to execute a code block

Searching for program: no such file or directory, ipython

I would be thankful for some help.

I got the following error when running ob-ipython.

In emacs message buffer, I got

No error output for ob-ipython-driver
No error output for ipython (jupyter console 4.0.3)

I run ubuntu 14.04 with emacs 24.5. I installed ob-ipython from MELPA and pointed the load path in emacs init file. I also have tornador installed.

The error message contains very little information. I searched around but could not find a thread for similar issue.

appreciate input.

Is there a way to have graphics not be inline, so that we can work with them interactively?

What is needed to make ob-ipython work with ipython3. I think i am quite close:

I made the following changes:

(defun ob-ipython--kernel-cmd (name)
  (-concat (list "ipython3" "kernel" (format "--IPKernelApp.connection_file=emacs-%s.json" name))
           ob-ipython-kernel-extra-args))

(defun ob-ipython--kernel-repl-cmd (name)
  (list "ipython3" "console" "--existing" (format "emacs-%s.json" name)))

(defun ob-ipython--create-driver ()
  (when (not (process-live-p (ob-ipython--get-driver-process)))
    (ob-ipython--create-process "ob-ipython-driver"
                                (list (locate-file (if (eq system-type 'windows-nt) "python.exe" "python3")
                                                   exec-path)
                                      ob-ipython-driver-path
                                      (number-to-string ob-ipython-driver-port)))
    ;; give driver a chance to bind to a port and start serving
    ;; requests. so horrible; so effective.
    (sleep-for 1)))

I also set the following file-local variables in a .org file where I want to use ipython3:

# Local Variables:
# org-babel-python-command: python3
# python-shell-interpreter: ipython3
# End:

When starting work on an ipython notebook, I get the warning:

Warning (python): Your `python-shell-interpreter' doesn't seem to support readline, yet `python-shell-completion-native' was t and "ipython3" is not part of the `python-shell-completion-native-disabled-interpreters' list.  Native completions have been disabled locally. 

Using this, ob-ipython is able to send start an ipython3 kernel and C-c C-c sends code to it. However, the results are not displayed in the :RESULTS text. However, I can attach to the running session using a console and inspect the variables and they are set based on the code in the org-mode file. What other changes are necessary to make this work with ipython3?

When exporting to LaTeX ipython code blocks, only the results get exported, even though :exports both is explicitly included.

The following sample org file fails to output the ipython code, but outputs only the results:
'''

+LATEX_CLASS: article

• tema 1
  some text and ipython code

  initialize ipython kernel

  #+BEGIN_SRC ipython :session :exports both
  acf_time = 10.45678
  #+END_SRC

+RESULTS:

• tema 2
  more ipython text and code

  +name: ipython_acf

  +BEGIN_SRC ipython :session :exports both

  '{:.3f}'.format(acf_time)

  +END_SRC

• tema 3
  and now python code

  +name: python_acf

  +BEGIN_SRC python :session :exports both

  '{:.3f}'.format(acf_time)

  +END_SRC

+RESULTS: python_acf

: 10.457

The acf time in ipython export is call_ipython_acf()

the acf time in python export is call_python_acf()
'''
The produced pdf is included below.

🙏

It would be super-handy to be able to round-trip an ipython org notebook to the .ipynb format used by ipython notebook.

#+begin_src ipython :session :results output
print "Hello, world!"
#+end_src python

Yields results in the ob-ipython-stout buffer but nothing in the #+RESULTS: section

Anyone else seeing this problem?

Thanks again.

No idea what the flow here should be but hooking in to tramp would be cool.

Also see #53 #11

This looks very good but, to really be useful, it needs to be asynchronous with the kernel evaluation.

Using 'import time; time.sleep(10)' blocks for 10s.

Just a little enhancement. The Help buffer can be quit with "q" and is put automatically in evil motion mode. I think it is more convenient for those readonly buffers.
Thank you!

I just pulled the recent repo and get the error "Trying to parse HTTP response code in odd buffer". After checked the Issue #22 and 33, I found I can solve the problem with (setq python-shell-interpreter "/usr/local/bin/python"). However, I take the courage to ask: if there is other solution instead of this? And here is the reason:

I use the Elpy mode for my python-mode and I really enjoy that. I set (elpy-use-ipython) to use ipython for Elpy. If I set the python-shell-interpreter to python, the ob-ipython will works fine but broke the Elpy workflow. Interesting thing is I did not have this problem with previous version of ob-ipython.

BTW, thanks @gregsexton for this great package. I used to use EIN before but not anymore since I found ob-ipython, I do prefer the Org-mode more. And if anyone can auto complete with company-mode from different source blocks under the same :session, could you kindly give me some info on your setup, as I still suffer the Issue 54.

Many thanks
Fanpeng

Hi there,
I'm trying to set up ob-ipython under spacemacs.

I installed ipython3, python3-tornado, python3-zmq via sudo apt-get install

The packages dash, s, f and ob-ipython are loaded the spacemacs way:
(setq dotspacemacs-additional-packages '(dash s f ob-ipython)

By applying this way of loading packages in spacemacs no configuration will be associated with those packages. So either I have to create a private layer for ob-ipython in spacemacs or I can define the necessary configuration within dotspacemacs/user-config.

What do I have to configure or tell org-babel when I get the following message when I try to evaluate a SRC block?: No org-babel-execute function for ipython

When I try running C-c C-c for a source code block, I get Process Python not running.

I have found two ways around this:

1. Run M-x run-python first.

2. Switch the following in ob-ipython.el (a trick I got from a redditor on /r/emacs).

(defun ob-ipython--kernal-repl-cmd (ameE)
  (list "ipython" "console" "--existing" (format "emacs-%s.json" name)))

for

(defun ob-ipython--kernal-repl-cmd (ameE)
  (list "jupyter" "console" "--existing" (format "emacs-%s.json" name)))

Any idea why this works? Both solutions feel wrong because in 1) I have to run a command every time and 2) I have to modify the source code which ruins any chance of upgrading potentially.

I sometimes produce data files and I am wondering if it's possible to print a link to them as a file path.
In python for example I can do

#+begin_src python :results file
return "a/file/path.here"
#+end_src

#+RESULTS:
[[file:a/file/path.here]]

I am experiencing the the issue exactly as described in #12 with emacs 25 and or 8.3
with ob-python freshly installed from MELPA, version 20151010.307
I am running on Linux Mint 17.3 Rosa.

Hi, this isn't exactly an issue, but:

How do you preserve your window-setup? mine jump around when I enter a source block, close it again, etc. etc.

thanks!

I receive the following messages when trying to run IPython code blocks:

I am on OSX and Emacs 24.5. Any ideas?

Currently we only support png output. SVG would be nice.

Does IPython support SVG using %matplotlib inline?

I usually have ipython notebook running on a remote server, which I then connect to over ssh using port forwarding. These are the commands I usually run.

ssh -L 8888:127.0.0.1:8888 myserver
ipython notebook --port 8888 --no-browser

Then, I open 127.0.0.1:8888 in the browser on my local machine. Is there an easy way to do this sort of workflow in ob-ipython?

I recently upgraded my Ipython versions and when evaluating a codeblock the system would stand still trying to: Contacting host: localhost:9988

If I kill the process I can read in ob-ipython-oi-ipython-driver

/home/oscar/miniconda/envs/dev/lib/python2.7/site-packages/IPython/kernel/__init__.py:13: ShimWarning: The `IPython.kernel` package has been deprecated. You should import from ipykernel or jupyter_client instead.
  "You should import from ipykernel or jupyter_client instead.", ShimWarning)
['/home/oscar/.emacs.d/elpa/ob-ipython-20150704.457/driver.py', '9988']

Which is not much information for me.
I change nevertheles IPython.kernel for jupyter_client. That did not improve things.
When evaluating a block, it gets stuck in the same step.

If I give the block a session name I do get to an error the ob-ipython-debug says

Hi,

I have a specified 'matplotlibrc' file with the same settings of plt.show() and plt.savefig(). But when I C-c C-c on the code block, the resulting image has a very low resolution that different from I directly run the python code outside the org file. How can I solve this, namely make the output image inside org mode the same as plt.same() and plt.savefig()? Thanks !

Updated: I put

import matplotlib
print(matplotlib.matplotlib_fname())

in the org code block, which gives

~/.matplotlib/matplotlibrc'

I think matplotlib is using the same config as which I run the python outside a org file.

Since ipython/jupyter upgrade, ob-ipython-inspect causes "Internal server error". Traceback from the ob-ipython-client-driver buffer suggests a missing/non-escaped character in json.decoder?

According to the ob-ipython menu in paradox's paradox-list-packages:

ob-ipython is an installed package.

     Status: Installed in `~/.emacs.d/elpa/ob-ipython-20151010.307/' (unsigned).
    Archive: n/a
    Version: 20151010.307
   Requires: s-1.9.0, dash-2.10.0, dash-functional-1.2.0, f-0.17.2, emacs-24
    Summary: org-babel functions for IPython evaluation
   Homepage: http://www.gregsexton.org
   Keywords: literate programming reproducible research 
    Other versions: 20151010.307 (melpa).

Still, when I use M-x no ob-ipython related functions show up. And when I begin typing ob-ipython in a elisp buffer, no functions show up. Furthermore, this happens: #35 . This must mean that the package is not properly installed in some way.

Where can I begin to debug this?

When I try to run the example

#+BEGIN_SRC python :session mysession :exports both
  def foo(x):
      return x + 9

  [foo(x) + 7 for x in range(7)]
#+END_SRC

I get a no-org-babel-execute function for ipython .

However, changing from

#+BEGIN_SRC ipython ...

to

#+BEGIN_SRC python ...

makes it work.

Is this a documentation mistake? If not, how do I fix my no-org-babel-execute function for ipython error?

Hi,
it seems that command line parameters have changed. I get (cropped to the main information)

[TerminalIPythonApp] CRITICAL | Bad config encountered during initialization:
[TerminalIPythonApp] CRITICAL | Unrecognized flag: '--port'

Process client-driver exited abnormally with code 1

and

[TerminalIPythonApp] CRITICAL | Bad config encountered during initialization:
[TerminalIPythonApp] CRITICAL | Unrecognized flag: '--conn-file'

Process kernel-default exited abnormally with code 1

(which probably also results in Issue #59). It seems that some of the cli parameters have changed, as indicated here: https://github.com/ipython/ipython/wiki/Cookbook:-Connecting-to-a-remote-kernel-via-ssh

% jupyter --version
4.1.0

% ipython --version
4.2.0

Is there any way to display multiple inline images output in the result block?

I've just started to try to use ob-ipython. Overall I think it's very good, but I do have one problem with it. Namely, I can't reliably get the org file to export. For instance, just now I successfully exported to HTML, then tried to export to PDF and got:

No output was produced to write to a file.

I've appended the file I'm using.

I suspect that the problem may be that I'm not using org-mode correctly, as I hadn't used in it a long time prior to this experiment. Thoughts? Thanks.

When executing a code block I get:
Code block produced no output.
in the minibuffer and the results remain blank.

The code is evaluated, but no output is produced, I have tried the the examples and my own code blocks with a minimal configuration file.

We currently have :kernel support but this doesn't work across all features.

• Seems you can only have one REPL and it's called Python. This then
  gets used to do autocomplete in python buffers. If it's not actually
  a python repl this causes all manner of failure.
• Opening a src block opens it in python mode
• You have to use the session arg to mix code. [I mentioned this in
  the README.]
• Variables and tables don't work generically. Not sure how to fix this.
• Rename to ob-jupyter

Hi,

this seems to be an awesome package, but I'd really like to use it with the julia kernel instead. Do you plan to support alternative backends, or could you give me a brief overview which parts of your code I'd have to change to add this myself?
thanks,
Sebastian

Hello,

I use Emacs with a dark background. Inline matplotlib plots by default have white background which is OK. However, the tick labels and axes labels have black facecolor and are transparent. I.e., the facecolor and the backgroundcolor is dark and they are not readable. Is there a workaround, how I can change either the transparency of this region, or the facecolor?

Thanks,
Dominik

Hello, when I execute a code block, I get the following warnings in my python session:

[TerminalIPythonApp] WARNING | Subcommand `ipython console` is deprecated and will be removed in future versions.
[TerminalIPythonApp] WARNING | You likely want to use `jupyter console`... continue in 5 sec. Press Ctrl-C to quit now.

I'm working with some notebook from ein and I now want to write some stuff to an org-mode file. Is there a way to attach the org block to this kernel?

I am new to org mode so I am possibly doing something very basic wrong. Do you know why I get this error when I Ctrl-c,c my python code?

I tried the code as shown in the example document. I first import matplotlib.pyplot and numpy in the first session code block In the org-mode ipython mode buffer for this code block, I can get auto complete after I do np. or plt. However when I started another code block under the same session, the auto complete no longer works. It was clearly shown working in the screenshot provided by @gregsexton, so I wonder if anyone has the same problem and could give me some suggestions? Thanks in advance

Some information:
I use Elpy for the python mode, which use company mode for auto completion.

Yes, really. Sorry for being so picky, but you are linking to the 'old' version of EIN. TKF did some amazing work, but his code has not been updated in a long time and only works with IPython 1.0 and earlier. I have taken his hard work and updated it to work with IPython 2.x and beyond.

Thanks - I am really looking forward to trying out ob-ipython. Your comment on org having better markup and organizing features is spot on, and something I wish I had the time to implement in EIN.

Hello,

First, thanks for the awesome package. I am using Emacs 24.5 on Windows 7 with Python 3.4 and Ipython 3.1.0.

I installed ob-ipython from master (it does not appear to be on melpa yet), and I have all of the dependencies installed.

When running an ipython block, I get the following messages and no output:

executing Ipython code block...

Executing does create a REPL buffer and a kernel buffer.

Edit - here is the backtrace from Emacs:

At the moment ob-ipython will look for the first python it finds in PATH, but this won't work too well if a user has multiple python environments (like conda).

One thought - use Python Shell Exec Path as the default, but allow the user to specify a custom value.

in melpa ob-ipython 20160305.843, opening ipython blocks in org-babel throws me into ipython with python 2 instead of python3.

python-mode opens correctly with anaconda ipython with python 3 after having set
(setq python-shell-interpreter "~/anaconda3/bin/ipython3")
, and ob-ipython connects to it when previously opened by python-mode manually.

I run on ubuntu with ipython and python installed; anaconda version is on my path (shell opens anaconda ipython by default).

I thought after Issue 32, python-shell-interpreter was used.

I tried adding any of these, but none change it:

  (setq python-shell-exec-path "~/anaconda3/bin")
  (setq python-shell-interpreter "~/anaconda3/bin/ipython3")
  (setq org-babel-python-command "~/anaconda3/bin/ipython3")

Am I overlooking something?

I'm trying to use the values stored in variables as strings in my floating text. My current approach
for this is.

#+name print_acf_val
#+begin_src ipython :session :exports none 
    '{:.3f}'.format(acf_time)
#+end_src

The acf time for this process is call_print_acf_val().

In latex that gets evaluated to

The acf time for this process is ='10.452'=

This is not very ideal to me because it looks ugly. I would ideally like that the latex output looks like

the acf time for this process is 10.452

In fact that is what happens when I use the normal python interpreter in org-mode

#+LATEX_CLASS: article

# initialize ipython kernel
#+BEGIN_SRC ipython :session :exports none
acf_time = 10.45678
#+END_SRC

#+name: ipython_acf
#+BEGIN_SRC ipython :session :exports none
'{:.3f}'.format(acf_time)
#+END_SRC

#+name: python_acf
#+BEGIN_SRC python :session :exports none
'{:.3f}'.format(acf_time)
#+END_SRC

The acf time in ipython export is call_ipython_acf()

the acf time in python export is call_python_acf()
