Tests are failing

[jpz]

I have 4 test failures. I don't know if it's significant but just to let you know. The errors occur both on MacOS and a Linux VM (both without GPU).

Here are two of the smaller ones:

====================================================================== FAIL: test_entropy (gaussian_process_test.TestMultiFull)
