segmentation fault while pytest

[Oren]

Old builds stopped working recently. We get a segmanatation fault in something related to pymongo / or maybe to tensorflow.

Since we did not lock the packages yet, it happens to us from time to time that a new python package version breaks something. Yet this time, it is really strange, and we don't even see the start of the tests, it happens before that. Did not find the descrepency in what we do at office and the environment on bitbucket.
