[Zoo-discuss] python module shapely failed to load

[Richárd Kiss]

Hi,

I would like to use shapely in my zoo wps python script.
It works fine via bash shell (I have installed shapely, and geos) but when
executed by zoo-project, I get the following output:

Python module test_service cannot be loaded.
Message: TRACE: (10, 'No child processes') <type 'exceptions.IOError'>
Unable to run your python process properly.
Please check the following messages : ['
File "/usr/lib/cgi-bin/test_service.py", line 27, in <module>\n from
shapely.wkt import dumps, loads\n', '
File "/usr/lib/python2.7/dist-packages/shapely/wkt.py", line 4, in
<module>\n from shapely import geos\n', '
File "/usr/lib/python2.7/dist-packages/shapely/geos.py", line 54, in
<module>\n _lgeos = load_dll(\'geos_c\', fallbacks=[\'libgeos_c.so.1\',
\'libgeos_c.so\'])\n', '
File "/usr/lib/python2.7/dist-packages/shapely/geos.py", line 37, in

File "/usr/lib/python2.7/ctypes/util.py", line 253, in find_library\n

File "/usr/lib/python2.7/ctypes/util.py", line 246, in
_findSoname_ldconfig\n f.close()\n']

I use ubuntu 14.04 and zoo version 1.4 and 1.5, and get the same results.

The test script is very simple derived from the test_service.py:

import zoo
from shapely.wkt import dumps, loads
def HelloPy(conf,inputs,outputs):
outputs["Result"]["value"]=dumps(loads('POINT (0 0)'))
return zoo.SERVICE_SUCCEEDED

Any idea how to fix this?

Best regards,
Richard
