Before Change

    y = sndi.gaussian_filter(x, sigma)

After Change

    out = sndi._ni_support._normalize_sequence(sigma, 2)
    assert_equal(out, sigma)
    // Also include the OPs original example to make sure we fixed the issue
    x = np.random.normal(size=(256, 256))

    for i in 2**np.arange(6):
        perlin += sndi.filters.gaussian_filter(x, i, mode="wrap") * i**2
    // This also fixes gh-4106, show that the OPs example now runs.
