Your PyTorch Code on Trainium: What Actually Breaks

AWS Trainium chips cost less per training run than equivalent GPU instances, but historically you had to rewrite your training loop around the Neuron SDK. TorchNeuron changes that. It registers a native PyTorch backend, so import torch_neuronx plus a small compile step covers most of the porting wo…
