From david.ve...@gmail.com on 2013-03-08T01:18:17Z I think I made a mistake, this is related to issue #1291 , but not the same? I also have the same problem on the development branch in combination with PyQt 4.10 Status: New |

From david.ve...@gmail.com on 2013-03-08T01:20:39Z To be more precise, I get the second traceback, since issue #1291 seems to be resolved on the dependency check at startup, but not with the ipython plugin? |
|
From david.ve...@gmail.com on 2013-03-08T01:44:26Z This is an Ipython issue, and it seems like they already took care of this issue, see ipython/ipython#2831 and corresponding pull request. Even thought his issue a show stopper there is nothing Spyder can do about it I think... |
|
From david.ve...@gmail.com on 2013-03-08T02:00:39Z I can confirm that using ipython from git resolves this issue for me. |

From toliman....@gmail.com on 2013-03-08T12:56:26Z Just installed ipython from github (1.0dev). When starting Spyder now, I do not get the option to open an ipython interpreter or console anymore. The "Interpreters" menu just offers "Open interpreter". ipython works fine from the command line. |

From david.ve...@gmail.com on 2013-03-09T08:18:26Z I don't know how spyder probes for ipython, but are you sure ipython got installed correctly? I have no idea about the possible pitfalls when installing ipython (on Arch Linux here, and I dully used the iptyhon-git package). Further, I don't know if ipython 1.0dev brakes spyder 2.1.x or not. Are there any tracebacks? You could try to run spyder in debug mode: spyder --debug. You could try in combination with spyder 2.2beta (I am running spyder 2.2dev), or you can easily run spyder 2.2dev from source with the bootstrap method (no need to install/uninstall any other spyder version, see here: https://code.google.com/p/spyderlib/wiki/NoteForBetaTesters)? What Linux distribution are you using? |

From toliman....@gmail.com on 2013-03-09T12:16:14Z I am using CentOS 6.3. Ipython 1.0.dev starts ok from the command line. spyder-2.2.0beta3 does not work at all on my system. Attempting to start it (with or without debug option) yields only: Segmentation fault (core dumped) |
|
From toliman....@gmail.com on 2013-03-09T14:00:15Z I commented out the version checks in spyder for ipython, then I get the all the menu entries. When I try to open a new IPython kernel, I get the error message: |

From david.ve...@gmail.com on 2013-03-10T03:44:21Z pyzmq is an optional Ipyhton dependency for the qtconsole (at least, that's how the Arch Linux package states it). Do you have pyzmq installed on your system? As you are saying, I guess Ipython < 1.0 came along with pyzmq, but 1.0 and above doesn't? See also some notes on the Ipython dependency here: http://ipython.org/ipython-doc/dev/install/install.html#dependencies-for-ipython-zmq . Sorry for not being much of help here...but thanks for trying to get to the bottom if it anyway! |

From ghisv...@gmail.com on 2013-03-10T05:51:19Z I am having the same issue on current Ubuntu Raring snapshot, spyder is at v2.10, IPython at v0.13.1 and PyQt at v4.10. I opened a bug report on launchpad and linked it to this issue. |
|
From david.ve...@gmail.com on 2013-03-10T06:17:21Z ghisvail, just to be clear: both bugs are fixed upstream, the important issue for the distributions is to either backport the changes (for spyder: https://code.google.com/p/spyderlib/source/detail?r=2c93f12f1e1b , for Ipython: ipython/ipython@8f74907 ) or to wait until the next releases. For Spyder: v2.2, there already is a stable beta3 or we have to quickly release a 2.14 that contains the fix. I have no idea about Ipython release plans... I guess downgrading pyqt is not on the table. If Ubuntu is still at spyder v2.10 (dates back to May 2012...), somebody should step up to package an updated version. |

From david.ve...@gmail.com on 2013-03-10T08:58:23Z Toliman, just because I am curious, where can you lookup which package versions are used in which CentOS version? I found this site for Fedora: https://apps.fedoraproject.org/packages/ , but couldn't figure out where CentOS has something similar. |
|
From toliman....@gmail.com on 2013-03-10T11:01:34Z David: Regarding pyzmq: Yes, I have it installed, but the problem is that spyder tries to import the package through the IPython hierarchy, the traceback is: File "/opt/python2.7/lib/python2.7/site-packages/spyderlib/widgets/externalshell/startup.py", line 37, in Regarding stable Spyder v2.2beta3: As I mentioned in Regarding CentOS package lookup: |

From david.ve...@gmail.com on 2013-03-10T11:32:13Z I've just checked my IPython from git package, and it does contain the zmq module (on Arch Linux, this is: /usr/lib/python2.7/site-packages/IPython/kernel/zmq/). How it is installed from the git sources goes as follows: Is it be possible something went wrong with your IPython installation? If I check the IPython sources on github, it still includes zqm though: https://github.com/ipython/ipython/tree/master/IPython/kernel/zmq (github master), and here for the 0.13 tree: https://github.com/ipython/ipython/tree/0.13.x/IPython/zmq |
|
From toliman....@gmail.com on 2013-03-10T12:10:45Z I downloaded the IPython package as zip from https://github.com/ipython/ipython with branch "master" selected, unzipped it and installed it using "python2 setup.py install". So I do not know that could be wrong there. If you look at the links you quoted, in the 0.13.x tree the zmq directory is a sub-directory of IPython whereas in the master tree it is a sub-directory of kernel, therefore I would expect the command "from IPython.zmq.ipkernel import IPKernelApp" to fail. I tried to modify the import statement to "from IPython.kernel.zmq.ipkernel import IPKernelApp" but that does not work either, because the class IPKernelApp is no longer defined in ipkernel.py. https://github.com/ipython/ipython/blob/0.13.x/IPython/zmq/ipkernel.py shows the class IPKernelApp definition starting line 803. https://github.com/ipython/ipython/blob/master/IPython/kernel/zmq/ipkernel.py ends at line 791, and does not have the class class IPKernelApp defined anywhere else in the file as far as I can see. |

From david.ve...@gmail.com on 2013-03-10T12:49:57Z I am still not being useful :-) ... let me try to recap the problem and maybe we could get the attention of one of the developers (I am just trying to help out a bit, not a dev here)
Some less ideal temporary options:

From david.ve...@gmail.com on 2013-03-10T12:56:46Z Just checked the IPython mailing list, and they are going to release a 0.13.2 version (no time frame mentioned), and the version checking bug has been backported: https://github.com/ipython/ipython/issues?labels=backport-0.13.2&state=closed http://mail.scipy.org/pipermail/ipython-dev/2013-March/011208.html So in theory, and as far as I can grasp the problem, I would assume IPython 0.13.2 and Spyder 2.1.14 would solve your problem when released... |
|
From toliman....@gmail.com on 2013-03-10T13:58:55Z David, thanks for trying to help! It helps me to narrow the cause down. The only problem: Everytime I fix something, something else breaks ... Let me add to your problem summary:
I have not tried to backport the IPython version checking fixes. |
|
From david.ve...@gmail.com on 2013-03-10T14:06:13Z a few hours ago, the version checking bug in IPython got backported on the 0.13.x branch: https://github.com/ipython/ipython/commits/0.13.x (issue #2831) |
|
From david.ve...@gmail.com on 2013-03-11T08:15:14Z FYI, Spyder 2.1.13.1 has been released and fixes issue #1291 . One down (Spyder), one to go (IPython) |
|
From pierre.raybaut on 2013-03-11T09:36:26Z Let's close this issue now that v2.1.13.1 fixes the Spyder related bug. Regarding IPython, there's not much we can do now that the IPython development team has take action on this. Status: Fixed |

Python Version: 2.7.3
Qt Version: 4.6.2, PyQt4 (API v2) 4.10 on Linux

When starting spyder I get the following error message:
