KS Test Error

[HNLala]

The function two_sample_test can't seem to execute the KS test. The problem it runs into, apparently, is that the function compute_null_distribution does not return a numpy array when executed for a KS test. It works as expected when I added the following block:

if not isinstance(test_null, np.ndarray):
    test_null = np.array(test_null)
