cc @ericl @pcmoritz any idea where this was introduced? It looks like new opencv-python wheels were uploaded today https://pypi.python.org/pypi/opencv-python/3.3.0.10. Maybe that is the problem.

[pcmoritz]

this is a duplicate of https://github.com/ray-project/ray/issues/922

My guess is that the version of opencv2 is different now or something related.

[robertnishihara]

Fixed by #926.

Got this issue in Docker when installing opencv-python; fixed it with
apt update && apt install -y libsm6 libxext6 libxrender-dev
