gaussian_query_test.py tests fail

Cloned the repo, conda install tensorflow, followed setup instructions inside the repo and then tried to run gaussian_query_test.py but it seems that some of the tests fail.

Running tests under Python 3.7.5: //anaconda3/envs/tf/bin/python

FAILED (failures=2, errors=1, skipped=1)

Start with gaussian_query_test.py and rerun the test file in the documented Python/TensorFlow environment. Inspect the eager-execution failure and the noise-related assertions shown in the traceback. Done means the previously failing tests pass without breaking the tests that already succeed.
