AttributeError: 'Evaluator' object has no attribute 'frame_from_codeobj' #16

riccardomurri · 2013-08-19T12:48:30Z

I'm trying to install Falcon from sources (commit 9444f0f); I get no
errors but the resulting interpreter does not run scripts:

rmurri@idsgi02:~/sw/src> source rjpower-falcon-9444f0f/bin/activate

(rjpower-falcon-9444f0f)rmurri@idsgi02:~/sw/src> which python
/home/user/rmurri/sw/src/rjpower-falcon-9444f0f/bin/python

(rjpower-falcon-9444f0f)rmurri@idsgi02:~/sw/src> python -m falcon
Usage: -mfalcon <script> <args>

(rjpower-falcon-9444f0f)rmurri@idsgi02:~/sw/src> python -m falcon rjpower-falcon-9444f0f/test/test_math.py
Traceback (most recent call last):
  File "/home/user/rmurri/sw/lib64/python2.7/runpy.py", line 162, in _run_module_as_main
    "__main__", fname, loader, pkg_name)

    exec code in run_globals
  File "/home/user/rmurri/sw/src/rjpower-falcon-9444f0f/src/falcon/__main__.py", line 24, in <module>
    main()
  File "/home/user/rmurri/sw/src/rjpower-falcon-9444f0f/src/falcon/__main__.py", line 20, in main
    f_frame = falcon.evaluator.frame_from_codeobj(code)
AttributeError: 'Evaluator' object has no attribute 'frame_from_codeobj'

The only warning I can see in the installation log (details below) is the following:

src/falcon/rinst.h:47: Warning 503: Can't wrap 'operator PyObject*' unless renamed to a valid identifier.

How can I go on debugging this issue?

Thanks,
Riccardo

Hi Riccardo,

It looks like you might be working against a broken version (I know Alex
has been refactoring things the past few weeks).

I just tried downloading and building against the latest master and it
works for me; please try using the latest version and let me know:


wget -O- https://github.com/rjpower/falcon/archive/master.tar.gz | tar -xz
cd falcon-master
python setup.py build

PYTHONPATH=build/lib.linux-x86_64-2.7/:src/falcon python -m falcon
benchmarks/fasta.py

I'm trying to install Falcon from sources (commit 9444f0fhttps://github.com/rjpower/falcon/commit/9444f0f);
I get no
errors but the resulting interpreter does not run scripts:

f_frame = falcon.evaluator.frame_from_codeobj(code)

The only warning I can see in the installation log (details below) is the
following:

src/falcon/rinst.h:47: Warning 503: Can't wrap 'operator PyObject*' unless renamed to a valid identifier.

How can I go on debugging this issue?

Thanks,
Riccardo

Hello,

thanks for the quick reply! Indeed, with the latest commit I can
successfully run the tests.

However, when I turn to the code I really wanted to test I get a SIGSEGV:

rmurri@idsgi02:/sw/src> source rjpower-falcon-dd15b9b/bin/activate

Is there any way I can debug this?

Thanks,
Riccardo

Hi Riccardo,

It looks like you might be working against a broken version (I know Alex
has been refactoring things the past few weeks).

I just tried downloading and building against the latest master and it
works for me; please try using the latest version and let me know:
wget -O- https://github.com/rjpower/falcon/archive/master.tar.gz | tar

cd falcon-master

I'm trying to install Falcon from sources (commit 9444f0f<
9444f0f>);
I get no
errors but the resulting interpreter does not run scripts:

The only warning I can see in the installation log (details below) is
the
following:

src/falcon/rinst.h:47: Warning 503: Can't wrap 'operator PyObject*'
unless renamed to a valid identifier.

How can I go on debugging this issue?

Thanks,

Hi Riccardo,

Sorry for the segfault, crashing other people's computers is always embarrassing. Can you send us the code so we can figure out what went wrong?

Thanks,
Alex

riccardomurri · 2013-08-19T20:13:58Z

Hi Alex, Russel,

thanks for your quick replies. I am trying to measure the speedup of
Falcon over CPython
on a code of mine: http://fatghol.googlecode.com/.
I have patched the sources with the attached diff so to remove the
dependency on external
C++ libraries.

You can just check out the code from GoogleCode's SVN and then run:

svn co http://fatghol.googlecode.com/svn/trunk fatghol
cd fatghol
patch -i falcon.diff
./mgn.sh -v homology 0,4

Thanks,
Riccardo
