Doubt regarding the BiT models

[sayakpaul]

We have the following bit models under timm:

['resnetv2_50x1_bitm',
 'resnetv2_50x1_bitm_in21k',
 'resnetv2_50x3_bitm',
 'resnetv2_50x3_bitm_in21k',
 'resnetv2_101x1_bitm',
 'resnetv2_101x1_bitm_in21k',
 'resnetv2_101x3_bitm',
 'resnetv2_101x3_bitm_in21k',
 'resnetv2_152x2_bitm',
 'resnetv2_152x2_bitm_in21k',
 'resnetv2_152x4_bitm',
 'resnetv2_152x4_bitm_in21k']

I wanted to know the ones that were pre-trained using ImageNet-21k and fine-tuned on ImageNet-1k.

According to this mapping from names to download path, those without the "_in21k" suffix were finetuned on ImageNet-1k (reference).
