I went back and checked out https://github.com/beijbom/pyspacer/commit/aee4cad5f65399f708f2f5223b71a55123474a86 which was before the EfficientNet integration and refactor, and the test passes there.

@qiminchen : I'm afraid something you did in the refactor caused this test to break. Can you trouble-shoot this please? To be clear, it may be that you fixed something that was broken, but either way, let's find out what it was so we can decide whether to update the test-fixture or revert back to the old code.

... you should be able to simply go through the list at https://github.com/beijbom/pyspacer/commits/master, check out each commit, build, test, etc. until you find the breaking change.

... I just checked and the test fails on the efficientnet_extractor branch that was merged. My bad for not running the docker test-suite before approving.
