Need help to locate the A1 training method described in timm paper

[SubrangshuDas]

From the link https://paperswithcode.com/paper/resnet-strikes-back-an-improved-training#code, CIFAR10 accuracy using A1 method (described in the paper) is 98.3%.

I want to reproduce the results, so that it gives me a good baseline to train on newer datasets using transfer learning.

num_classes = 10
net = timm.create_model('resnet50', pretrained=True, num_classes=num_classes).to(device)

However, I could not locate the python code to incrementally train the above model for CIFAR10 dataset using A1 training.
