Model card for convnext_base.clip_laion2b_augreg_ft_in1k#

A ConvNeXt image classification model. CLIP image tower weights pretrained in OpenCLIP on LAION and fine-tuned on ImageNet-1k in timm by Ross Wightman.

Please see related OpenCLIP model cards for more details on pretrain:

Feature Map Extraction#

# or equivalently (without needing to set num_classes=0)

output = model.forward_features(transforms(img).unsqueeze(0))
# output is unpooled, a (1, 1024, 8, 8) shaped tensor

output = model.forward_head(output, pre_logits=True)
# output is a (1, num_features) shaped tensor
