The following test fails because because `seq1 == seq2` returns a (boolean) NumPy array

I expected `unittest` to rely only on features of a `collections.abc.Sequence`,
which based on https://docs.python.org/3/glossary.html#term-sequence,
I believe are satisfied by a NumPy array.

If you know you might be dealing with NumPy arrays (as the import suggests), I think it's simply right to spell it as:

unittest.TestCase().assertTrue(np.array_equal([1., 2., 3.], np.array([1., 2., 3.])))

Or for pytest etc., simply:

assert np.array_equal([1., 2., 3.], np.array([1., 2., 3.]))
