ImportError on cv2.so

I am trying to run fast-rcnn on a cluster, where cv2.so is not installed for public use. So I directly move the cv2.so into a PATH, but it turns as:

/lib64/libc.so.6: version `GLIBC_2.14' not found

So I have to install the opencv on my local path again, this time it says:

ImportError: /home/username/.local/lib/python2.7/site-packages/cv2.so: undefined symbol: _ZN2cv11arrowedLineERNS_3MatENS_6Point_IiEES3_RKNS_7Scalar_IdEEiiid

This really confused me, could anyone give me a hand?

I know this is a little late, but I just got this same error with python 2.7 and opencv 3.1.0 on Ubuntu. Turns out I had to reinstall opencv-python. Running sudo pip install opencv-python did the trick.

The problem has been solved by some tryings.

Since I installed under my /.~local path, it should be noticed that [include],[bin] and [lib] should all point to the local version by modifying the bashrc.

I just change the lib path while the other 2 paths remained unchanged, which point to the cluster's opencv version 2.4.9.(Mine is 2.4.11)

I ran into the same issue, but for me PYTHONPATH looked something like:

PYTHONPATH=/usr/local/lib/python2.7/dist-packages:/opt/opencv2.4.9/lib/python2.7/dist-packages

Removing /opt/opencv2.4.9/lib/python2.7/dist-packages from the path provided the fix.

After struggling with the above solutions, the following one (source) solved my problem:

sudo pip install --upgrade opencv-python
