Caffe: python import caffe error: XDG_RUNTIME_DIR not set in the environment.

[wandering007]

Hello, guys!
I installed pycaffe following the document(which is simple)...
But when I entered import caffe in python, I just got the following error information:

caffe/pycaffe.py:13: RuntimeWarning: to-Python converter for boost::shared_ptr<caffe::Net<float> > already registered; second conversion method ignored.

BTW, I installed the newest version of caffe and my machine is Ubuntu 12.04.
Has someone been faced with this issue before? Needing help, thanks!

I have the same problem. (Pycaffe, Ubuntu 14.04)

Will post back if I figure out an answer

Please ask installation questions on the mailing list. If you're having trouble, you might want to try the Caffe Dockerfile to take care of installation for you.

_Please do not post usage, installation, or modeling questions, or other requests for help to Issues._
Use the caffe-users list instead. This helps developers maintain a clear, uncluttered, and efficient view of the state of Caffe.
