We don't override files created by this script (there is 3.4 branch which expects old sha / and tested with old file only).
It should be a new file (with date suffix -YYYY-MM). Also we need to update tests.

There are 2 links on the release page for yolov4-tiny.weights:

But both with the same content (sha1:451caaab22fb9831aa1a5ee9b5ba74a35ffa5dcb).

BTW, I have a copy of old file with download date 2020-07-03 (sha1:d110379b7b86899226b591ad4affc7115f707157).
