unfortunately, I did not have success with AP in Julia. The result is not consistent with python sklearn which was supposed to be more stable.

my comparison code is not correct. python start from 0, so I should add 1 for python labels. Julia implementation seems correct.

it turns out just some label value difference, the rand index is 1.0, so it is correct!
