I've installed the 2.2.31-1 graph-tool package for Ubuntu 13.10 x86_64 on my system. Although I can import it from within a regular Python 2.7.5 session without any problems, I can't seem to import it successfully from within a virtualenv in which I've installed a range of other packages (the virtualenv is configured to also access globally installed Python packages):
import graph_tool Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/dist-packages/graph_tool/__init__.py", line 100, in <module> dl_import("from . import libgraph_tool_core as libcore") File "/usr/lib/python2.7/dist-packages/graph_tool/dl_import.py", line 57, in dl_import exec(import_expr, local_dict, global_dict) File "<string>", line 1, in <module> ImportError: /usr/lib/python2.7/dist-packages/graph_tool/libgraph_tool_core.so: invalid mode for dlopen(): Invalid argument
Before I manually go through all of the packages installed in the virtualenv, does anyone have any ideas as to what sort of things might be causing the above import problem?
I've had some problems with this in the past with other boost.python modules (see: http://stackoverflow.com/questions/19663366/dlopen-fails-in-boost-python-mod...). Here are some context managers I use to import modules that are causing me problems:
Thanks, John - this fixed the problem. -- Lev Givon Bionet Group http://www.columbia.edu/~lev/ http://lebedov.github.io/
