* Add MAE evaluation * Add stochastic depth dropout * Add MAE * Drop assertion * Fix smooth cross entropy loss and mixup * Update comments * Add layer lr decay and weight decay * Update comment * Add test for MAE images_to_tokens * Disable BN update * Add BN before classification head * Format * Fix BN freezing * Cleanup * Use torch.no_grad instead of deactivating gradients manually * This is required as torch.no_grad doesn't change the model configuration while manual gradient deactivation/activation can have unintended consequences. For example, MAE ViT positional embeddings are parameters with requires_grad=False that should never receive an update. But if we use activate_requires_grad for finetuning we break those parameters. * Create new stochastic depth instances * Add mask token to learnable params * Add sine-cosine positional embedding * Initialize parameters as in paper * Fix types * Format * adjusted to existing interface * draft * remove * added modifications * added mae implementation with timm and example * formatted * fixed import * removed * fixed typing * addressed comments * fixed typing and formatted * addressed comments * added docstring and formatted * removed images to tokens method * Ersi lig 3910 update mae benchmark code (#1468) * modified imagenette benchmark * formatted * edited vitb16 benchmark * added the posibility to handle images of different sizes * formatted * removed comments * revert * changed import * initialize class token * specified that class token should be used * chabged architecture * addressed comments * formatted * Masked vision transformer (#1482) * added hackathon * changed comments * formatted * addressed comments * fixed typing * addressed comments * added pre-norm and fixed arguments * added masked vision transformer with Torchvision * weight initialization * cleanup * modifies imagenette benchmark * made mask token optional and adapted benchmarks * removed unused import * adapted to dynamic image size * moved positional embed init to utils * updated benchmark * adapted benchmark * moved mask token to decoder * revert example * removed example * removed file * inheriting from Module * reverted dataset paths * use timm's drop_path_rate * removed unused import * removed private method * changed slicing * formatted * path dropout only for fine tune * formatted * account for mask token in backbone * mask token of decoder * removed appending of mask token in params * resolved conflicts * formatted * adjusted examples * removed comment * added test * added message in case of ImportError * fixed skipping of test * removed example * handling the TIMM dependency * added note to docs for MAE installation * added unit tests for MAE with torchvision * removed unecessary maks token definition * addressed comments * moved test to separate file * added typing * fixed import * fixes typing * fixed typing * fixed typing * Ersi lig 4471 cleanup and merge mae branch (#1510) * renamed test class * fixed imports * ficed imports * fixed import * fixed imports and decreased batch size * format * removed comments * use function defined in utils * added docstrings * added doctrings * added docstring * formatted * formatted * import Tensor --------- Co-authored-by: guarin <[email protected]>
