pydev makes python.exe crash

[webhart]

I try to use a python.exe version (2.6.2)  that ships with the software-package ABAQUS on Windows 7, 64 bit. When launching it from the windows command prompt it works. When launching it from eclipse with pydev python.exe crahes and I get the following type of messages in the event-viewer. PATH and PYTHONPATH are the same in both cases. Where should I look for differences?

One additional information: I can run the python interpreter in eclipse using the "PyDev Console". Its output is
import sys; print('%s %s' % (sys.executable or sys.platform, sys.version))
C:\SIMULIA\Abaqus\6.10-1\Python\Obj\python.exe 2.6.2 (r262:71600, Apr  7 2010, 16:24:50)

Via execfile() I can successfully  run my scripts. But I still have no solution for running/debugging via "Debug Configurations…" because of the above mentioned crashes. Any suggestions please?

Does it crash always? I.e.: if you create an empty script at the root of your source project with a single print, does it also crash? (the part related to being at the source is important, as if the file is somewhere else, you may already import lots of things)

Cheers,

Fabio

Yes, even the single-print script crashes.  Nothing stands in the eclipse\.metadata\.log. This is the output from "See resulting command line"
C:\SIMULIA\Abaqus\6.10-1\Python\Obj\python.exe -u -v
\\nas1\W01\hart\eclipse\workspace\PostProcessor\src\simple.py

The PYTHONPATH that will be used is:

C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481\plugins\org.python.pydev_2.1.0.2011052613\PySrc\pydev_sitecustomize;\\nas1\W01\hart\eclipse\workspace\PostProcessor\src;C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481\plugins\org.python.pydev_2.1.0.2011052613\PySrc;C:\SIMULIA\Abaqus\6.10-1\Python\Lib

Have you tried starting eclipse from the same shell you're using when you run python?

Also, if you set in the shell the same PYTHONPATH

i.e.:
set PYTHONPATH=C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481\plugins\org.python.pydev_2.1.0.2011052613\PySrc\pydev_sitecustomize;\\nas1\W01\hart\eclipse\workspace\PostProcessor\src;C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481\plugins\org.python.pydev_2.1.0.2011052613\PySrc;C:\SIMULIA\Abaqus\6.10-1\Python\Lib

and execute that command line

C:\SIMULIA\Abaqus\6.10-1\Python\Obj\python.exe -u -v \\nas1\W01\hart\eclipse\workspace\PostProcessor\src\simple.py

does it work?

Cheers,

Fabio, thank you for the suggestions.

I did the following steps:
1. Open a shell
2. set path=c:\windows;c:\windows\system32;C:\SIMULIA\Abaqus\6.10-1\exec\lbr\;C:\SIMULIA\Abaqus\6.10-1\External
(The abaqus-python interpreter requires dlls that are in the abaqus folders)
3. set PYTHONPATH=C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481\plugins\org.python.pydev_2.1.0.2011052613\PySrc\pydev_sitecustomize;\\nas1\W01\hart\eclipse\workspace\PostProcessor\src;C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481plugins\org.python.pydev_2.1.0.2011052613\PySrc;C:\SIMULIA\Abaqus\6.10-1\Python\Lib
4. Execute the script via the command line: C:\SIMULIA\Abaqus\6.10-1\Python\Obj\python.exe -u -v \\nas1\W01\hart\eclipse\workspace\PostProcessor\src\simple.py
-> works
5. Launch eclipse (-arch x86_64) from the same shell: "C:\Program Files\eclipse\eclipse.exe"
6. Open a pydev console and choose the abaqus interpreter and run the script via execfile("\\\\nas1\W01\hart\eclipse\workspace\PostProcessor\src\simple.py") -> works
7. Run the same script via "Launch Configurations…"  -> crahses as shown in post 1

Best regards,
webhart

Can you do one more test:

Edit the file C:\Users\hart\.eclipse\org.eclipse.platform_3.6.1_1709980481\plugins\org.python.pydev_2.1.0.2011052613\PySrc\pydev_sitecustomize\sitecustomize.py

and add a

print "sitecustomize"

as the first line in that script and then run it from PyDev (as that's the first file executed by Python, I'm trying to discover if it crashes before or after entering in that file).

Cheers,

Fabio

hey guys,
after some searching I found the solution: Eclipse or PyDev adds some environment variables. Apparently Abaqus crashes if 'PYTHONIOENCODING' is set. So I just removed this variable within python and it worked.

import os
try:
    os.environ.pop('PYTHONIOENCODING')
except KeyError:
    pass
# now call abaqus
