WebAug 16, 2024 · I am loving the new CUDAGraph functionality in PyTorch. I am trying to graph a transformer-based model, and if I fix the shapes to always use the maximum sequence length, then everything works great. However, my training data comes in a few different sequence lengths. Let’s say for example’s sake I have 4 different sequence …

In the source of simpleCUDAGraphs sample it is much more clarify, but still I have not found a sufficiently instructive example.
