Failing Test Cases - Ubuntu 18.04 , Python 3.6.7

[riaz]

The build was successfuul, but unfortunately i am unable to read data.
I see a parrtern in the errors and all have to be in sumo/threedee.
Any pointers would be very helpful.

I created a docker image, with the environment suggested for building sumo-api , and it works!
Was anyone able to setup sumo-api on Ubuntu 18.04?

Could you share your dockerfile? Because the test_semantic_score fails even on my ubuntu 16.04 image

[nywenjing]

I found it work by installing opencv from source on Ubuntu 18.04

[riaz]

@nydragon Can you share which opencv version you installed? I still have issues
