Cheers, In Metalhead, consider the following model: bb = backbone( ResNet(50) ) model = UNet((256,256), 3, 10, bb) Need to get access to a specific activation map from the model’s encoder (actually, to a specific acti…

Cheers, Would like to confirm if the yhat array output of Metalhead.UNet model is limited to \[0:1\] elements. Apparently its upper bound is higher than 1. Model is instantiated as follows: backbone = Metalhead.backbon…

I have trained a Resnet18 using Flux on julia-1.10 rc1, actually I have trained multiple models with no trouble at all, but this week when I try to predict using my model I get a compilation error for my private package: …

I implemented a self-supervised learning algorithm, MAE (Masked Auto Encoder), based on Flux.jl and Metalhead.jl, It seems to work, especially when propagating forward, but during gradient descent, Zygote alerted me that…

Hi, I’m training the DenseNet from Metalhead.jl on the CIFAR-10 dataset which generally seems to work quite well. However, I can’t seem to find out how to access the output from individual layers in the Chain. I know a…
