A ResNeXt repeats a building block that aggregates a set of transformations with the same topology. Compared to a ResNet, it exposes a new dimension, cardinality (the size of the set of transformations) $C$, as an essential factor in addition to the dimensions of depth and width.
The weights from this model were ported from Gluon.
To load a pretrained model:
import timm
m = timm.create_model('gluon_resnext50_32x4d', pretrained=True)
m.eval()
Replace the model name with the variant you want to use, e.g. gluon_resnext50_32x4d. You can find the IDs in the model summaries at the top of this page.
You can follow the timm recipe scripts for training a new model afresh.
