The test "test_build_pipeline_idempotency" is not passing

I had installed fklearn with test dependencies and one of them not passed.

I had run the following commands in anaconda:

conda create -n fklearn_dev conda install python=3.6 pip install -qe .[test_deps] python -m pytest tests/

To reproduce the error you could run the following code in main fklearn folder:

from tests.training.test_pipeline import test_build_pipeline_idempotency test_build_pipeline_idempotency()

It should pass quietly, however I got the following error:
