Python - How to import module from .so file from egg file without using an absolute file path -


i built pyahocorasick library python setup.py bdist_egg command , uploaded onto spark pyspark job.

however, .so file inside pyahocorasick can't imported through pkg_resources.resource_filename() method on spark cluster security reasons.

traceback (most recent call last):   file "spark_datawash.py", line 251, in <module>     import ahocorasick   file "build/bdist.linux-x86_64/egg/ahocorasick.py", line 7, in <module>   file "build/bdist.linux-x86_64/egg/ahocorasick.py", line 4, in __bootstrap__   file "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 1152, in resource_filename   file "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 1696, in get_resource_filename   file "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 1726, in _extract_resource   file "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 1219, in get_cache_path   file "build/bdist.linux-x86_64/egg/pkg_resources/__init__.py", line 1199, in extraction_error pkg_resources.extractionerror: can't extract file(s) egg cache  following error occurred while trying extract file(s) python egg cache:    [errno 13] permission denied: '/home/.python-eggs'  python egg cache directory set to:    /home/.python-eggs  perhaps account not have write access directory?  can change cache directory setting python_egg_cache environment variable point accessible directory.

this how pyahocorasick import .so:

def __bootstrap__():     global __bootstrap__, __loader__, __file__     import sys, pkg_resources, imp      __file__ = pkg_resources.resource_filename(__name__, 'ahocorasick.so')     __loader__ = none; del __bootstrap__, __loader__     imp.load_dynamic(__name__,__file__) __bootstrap__()

can import .so resource_stream() instead of resource_filename() or other way without need read absolute file path? all.

btw, can't install pyahocorasick on every node on spark cluster other reasons. have upload egg-zipped distribution later use.
