Testfix

[loopylangur]

Hi,

I was able to reduce the running time of test_kissgp_classification_error test from 48 seconds to less than 18 seconds on my local machine by changing two hyper-parameters.

I also ran the test several times to ensure that the test is not flaky.

Environment:

python 3.6
torch==1.7.1
numpy==1.19.5

Is this something that you guys will be interested in? If yes, then I can help you optimize some other tests in this repo as well. If you have any other suggestions/edits I will be happy to integrate them as well. Please let me know.

Thanks!
