py*-spyder crashes on startup after (unexpectedly) entering _tkinter.so

Have you tried moving your ~/.spyder2-27 directory out of the way so it initializes with defaults?

I run spyder daily on 10.6.8, so I'm a little stuck here. You can try opening running spyder under pdb to see if we can narrow this down:

MacPro:~$ python
Python 2.7.3 (default, Oct 22 2012, 06:12:28) 
[GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pdb
>>> pdb.run("from spyderlib import start_app\nstart_app.main()")
> <string>(1)<module>()
(Pdb) cont

That didn't help. Spyder failed with the same errors.

Output of port echo active and rdepof:py27-spyder and xcodebuild --version ?

By the way, I just noticed that qt4-x11 is listed as a requirement for spyder, which I didn't have installed, but if I try to build it, I get an error saying that qt4-x11 is not supported on my OS. Is qt4-x11 really a requirement, or is this a mistake in the requirements list?

The trace shows a crash in libtk8.6. Current upstream maintained Pythons (like 2.7) do not officially support Tk 8.6 yet. On top of that, AFAIK, the Cocoa Aqua Tk 8.6 (the MacPorts +quartz variant) has had little exposure on any version of OS X, much less 10.6. You *might* have better luck installing the X11 version of Tk (-quartz). If you do find a bug in either Tk 8.6 or Python's Tkinter using 8.6, it would be helpful to open an upstream issue as you are on the leading edge here.

[eborisch (Eric A. Borisch)]

You might try py27-matplotlib -tkinter+qt4[+...] ... And the qt4-x11 is on the website listing (if I recall) as those lists are created on a Linux box.

[eborisch (Eric A. Borisch)]

Try running SPYDER_DEBUG=1 spyder and see if that reveals anything else.

RE:nad's comment, if you use py-matplotlib -tkinter it shouldn't enter into libtk8.6 at all -- worth a shot. I haven't been able to reproduce yet. I don't have +universal versions installed, and my Xcode is newer (4.0.2) FWIW.

Hi eborisch-

I ran the following:

sudo port self update
sudo port upgrade outdated

which updated py-spyder and py27-spyder to 2.2.5_2. When I run spyder, I continue to get the same error message. Please see attached error message.

Thanks! Joe

[eborisch (Eric A. Borisch)]

Can you post the results of 'SPYDER_DEBUG=1 spyder-2.7' ? You might also try moving ~/.spyder2-27 out of the way and see how it does with fresh preferences folder.

I can't seem to recreate the crash, so hopefully this will provide some insight into what is happening.

[joe.oboyle@…]

I've moved both ~/.spyder2/ and ~/.spyder2-27/ out of the way and run 'SPYDER_DEBUG=1 spyder-2.7'. Updated error messages attached. Thanks! Joe

[eborisch (Eric A. Borisch)]

How about the output from DYLD_PRINT_LIBRARIES=1 spyder-2.7 ?

I'm still trying to figure out why it's entering _tkinter.so. With py27-matplotlib installed with -tkinter it really shouldn't be.

Thanks for your help!

Error messages on spyder launch

[joe.oboyle@…]

I double checked py27-matplotlib. The installed version is

!555 [ ~ ] port echo installed |grep py27-mat
py27-matplotlib                @1.3.0_0+qt4 

I did an uninstall, clean, install cycle on py27-matplotlib with +qt4 -tkinter. The -tkinter appears to be by default, so isn't showing in the echo installed.

After reinstalling I did an uninstall, clean, install cycle on py{|27}-spyder. The error_msg.txt shows the results from running 'DYLD_PRINT_LIBRARIES=1 spyder-2.7'

Thanks! Joe

I have the same problem; I don't see yet why tkinter plays a role here at all. I don't need Tk/Tcl at all, and I would always prefer Qt4.

"port installed depends:py27-tkinter" gives:

The following ports are currently installed:
  py27-matplotlib @1.3.0_0+latex+qt4 (active)
  py27-opengl @3.0.2_0 (active)
  py27-pil @1.1.7_6 (active)

BTW: The ticket title is confusing; at least I am on 10.8.5.

[eborisch (Eric A. Borisch)]

Can you try deactivating py27-opengl to see if spyder works with it deactivated?

Exactly. That's why the entrance into (and subsequent crash within) _tkinter.so is confusing in the traces.

Updated subject to make slightly less confusing.

What does ~/.matplotlib/matplotlibrc contain for those experiencing crashes?

[hmeine (Hans Meine)]

I have only configured "backend : Qt4Agg" in matplotlibrc.

Yay! Deactivating py27-opengl helped! :-)

So how is py27-opengl loaded? Maybe through Qt? (I am using QtOpenGL in my own project successfully, but obviously spyder also uses pyobjc?)

[eborisch (Eric A. Borisch)]

If you want to track it down, try this after re-enabling py27-opengl

python2.7 -m pdb `which spyder` 

when you get to the Pdb prompt, enter

b /opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/OpenGL/__init__.py:177
cont

When it breaks on the line, print the backtrace ('bt').

Is the project where you are using it being edited in spyder? Perhaps when it is doing all of its magic to be able to intelligently edit the script, it runs the import (read in from your files) and crashes during that activity?

Glad to hear we have it narrowed down!

Closing; issues were not with spyder, but Tk.
