How does one uses IPython plugin for Spyder?

[Boris Gorelik]

So I have successfully started the IPython kernel by using the "Start
new IPython kernel" command. This blog post
http://spyder-ide.blogspot.com/2011/08/preview-of-new-ipython-plugin-for.html
says that an IPython frontend dockwidget is supposed to be created
automatically, but it doesn't. What am I doing wrong?

PS this screenshot shows my setup:

[Boris Gorelik]

I don't know whether this is connected, but it seems that Spyder uses
IPython that is different from the one installed on my system. As you
can see from the screenshot below, I have the newly released 0.12
version of IPython, while Spyder sees 0.12rc. My computer has been
restarted several times since the last IPython upgrade

Boris, this is probably due to the fact that Spyder is using a different
python interpreter than your main one. You can see what interpreter is
used in:

Tools > Preferences > Console > Advanced Settings > Python executable

No,  I have only one Python interpreter and I verified that it is the one that is specified in  Tools > Preferences > Console > Advanced Settings > Python executable 

I have also noticed that the script in "PYTHONSTARTUP" replacement has no effect on the opened consoles, which is too, very strange.

I need to clarify that the PYTHONSTARTUP variable is ignored only when opening IPython console, not the regular Python console

[Serge A. Salamanka]

so far ...
did anyone manage to utilize the features of ipython 0.12 in Spyder ?

I am using the Qtconsole plugin inside Spyder for .12 and .13dev, it
looks pretty good. The inline plots are snazzy.

Did this work for you out-of-box? I have Spyder 2.1.7 and Ipython 0.12 on WinXP and still can't make it work

I've been experimenting with it a little, and here's my experience so far using Python 2.7.2, Spyder 2.1.7, IPython 0.12 on Windows 7.

Under PyQt4 4.8.5:
I can successfully launch an IPython *interpreter* using the menu command "Interpreters...Open IPython interpreter", but of course this produces the standard warning in the IPython interpreter itself, saying "Warning: Spyder does not support GUI interactions with IPython >=v0.11
on Windows platforms (only IPython v0.10 is fully supported)." This is functioning as designed at the moment, so no concerns here. I can launch a new IPython *kernel* using the menu command "Interpreters...Start a new IPython kernel". The kernel itself appears to start, but the associated frontend plugin fails to launch. I get a traceback in Spyder's internal console that ends with "ValueError: API 'QString' has already been set to version 1".

Under PySide 1.1.0:
IPython *interpreter* launch produces the same results as with PyQt4. IPython *kernel* launch is successful, and the frontend plugin is also successful. Everything works fine, inline plotting works, etc.

I think Issue 805 is tracking this problem:

http://code.google.com/p/spyderlib/issues/detail?id=805

[matt]

My experience is very similar to Jed's.  However, I am tracking the development version of IPython so I had to change some version checks in Spyder so it will let me start a kernel.  I also am using the newest version of Spyder off the repository if that might matter.  The code I changed to use IPython .13dev is in my clone http://code.google.com/r/wmattanderson-test/source/checkout.  There's no real change, only allowing what works for .12 to work for .13.

Same problem with QString beeing set up to value 1

Spyder 2.1.7
Python 2.6.5
IPython 0.12
PyQt4 4.7.2

no front end in spyder when creating kernel

Issue 805

I can only get it to work with PySide.

How?
When I switch to PySide all I get is

TypeError: QWidget.setFocusPolicy(Qt.FocusPolicy): argument 1 has
unexpected type 'PySide.QtCore.Qt.FocusPolicy'

Strange, I've never seen that one...I am running Qt 4.7.4 via PySide 1.0.9

and also Ipython .13dev which should not matter.  If getting the same version of PySide doesn't fix the problem and you want to change to try Ipython .13dev you will have to change the spyder code a bit.  I did it on my clone, and it should be up to date...let me know how it goes

I will upgrade in a little bit and check it out

I am running Qt 4.7.4 via PySide 1.1.0 on Ubuntu 11.10, but
unfortunately I cannot downgrade to 1.0.9 to see if it works.

[Matt Anderson]

Nope, mine still works with 1.1.0

I'm on a 64 bit windows 7 box...but I would think that would make mine less likely to work easily.  I'm running mine from source from the bootstrap.py file.

How do you switch back to PyQt, since I have installed PySide I haven't tried?

[Philipp Lies]

Well, on Windows I use ipython 0.10 because 0.12 doesn't work at all. PySide doesn't work for me on Windows, I get
Traceback (most recent call last):

even though I set the PATH to point to PySide not PyQt. On Linux I just change the API selection in the Preferences to switch between PySide and PyQT which seems to work I guess.

That may be a bit beyond my depth...especially since I can't recreate the issues myself.  About all the advice I would have for you would be to use this website to get things working on Windows.   http://www.lfd.uci.edu/~gohlke/pythonlibs/
