C2_W1 Assignment: trying to understand source of unittest failure

Course Q&A Natural Language Processing NLP with Probabilistic Models
1

I have completed this week assignment, but the last unittest

w1_unittest.test_min_edit_distance(min_edit_distance)

gave me an error:

Distance matrix has wrong values.
	Expected: [[ 0  2  4  6  8 10]
 [ 2  0  2  4  6  8]
 [ 4  2  0  2  4  6]
 [ 6  4  2  0  2  4]
 [ 8  6  4  2  3  5]].
	Got: [[0 1 2 3 4 5]
 [1 0 2 4 6 7]
 [2 2 0 2 4 6]
 [3 4 2 0 2 4]
 [4 6 4 2 3 5]].
 15  Tests passed
 1  Tests failed

But I see that the expected result has this array in the first row - [ 0 2 4 6 8 10]. How is it possible?

If you open the w1_unittest.py file, you can read the test cases provided by the test_min_edit_distance() function.
