Hey

I would be very appreciative if anyone can share his training regime (res. increase script, etc') and hparams for finetuning these models and ofcourse the results you're getting and some general details of your downstream task :)

Also, amazing work and greatly appreciated @rwightman ! thanks :)

See #629, but I should point out tf_ models are not trained by me, they are from the official weights trained in tensorflow so those hparams are in the official code
