kats 0.2.0 ax-platform dependency

[yannmean]

According to the requirement.txt, kats requires ax-platform=0.2.9, however, when I install ax-platform 0.2.9, got the following message: kats 0.2.0 requires ax-platform==0.2.4, but you have ax-platform 0.2.9 which is incompatible.

The message indicates it requires ax-flatform 0.2.4..

Could you please tell me which version of ax-platform kats actually depend on? thanks.
