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? -- Lev Givon Bionet Group http://www.columbia.edu/~lev/ http://lebedov.github.io/
