Hi,

Thank you for your awesome work!

Could you update score result for efficientnetv2 models?

Thanks

@sh1ng it will probably be another week before I have updated results for all the models, I'm currenlty merging/adding a few more before I start, and it takes several days now to run the full set of validations. I can say that the results for those models was pretty close to the numbers listed in tensorflow impl, so no surprises aside from usual variations when moving between frameworks...
