Import error for densecrf.so: "undefined symbol" #42

Closed Ryan-Lima closed 6 years ago

Ryan-Lima commented 6 years ago

Using python 2.7.13 Anaconda 4.4.0 (64 bit) on Ubuntu 16.04 Installed pydensecrf from git as per instructions: no installation errors. However, when I issue

import pydensecrf.densecrf as dcrf

I get the following error

ImportError: /home/ryanelima/anaconda2/lib/python2.7/site-packages/pydensecrf/densecrf.so: undefined symbol: _ZTINSt8ios_base7failureB5cxx11E

I have tried uninstalling and reinstalling system cython and pip cython (both as user and root), but problem persists. Also tried

nm -C  /home/ryanelima/anaconda2/lib/python2.7/site-packages/pydensecrf/densecrf.so

Please advise

Thanks
