Fix anchor incorrectly initialized (#8891)

* Fix anchor incorrectly initialized Using --noautoanchor and --evolve simultaneously leads to anchor incorrectly initialized. --noautoanchor denotes anchors don't need to evolve, thus removing anchors from hyp will fix it. * Update train.py * Update train.py Co-authored-by: Glenn Jocher <glenn.jocher@ultralytics.com>
