Alternating the GPUs each layer is on didn’t fix it, but it did produce an interesting result! It took longer to OOM. The memory started increasing on gpu 0, then 1, then 2, …, until eventually it came back around and OOM. This means memory is accumulating as the forward pass goes on. With each layer more memory is allocated and not freed. This could happen if we’re saving activations or gradients. Let’s try wrapping with torch.no_grad and make required_grad=False even for the LoRA.
A tensor is an n-dimensional array where every element has the same dtype. A 1D tensor is a vector. A 2D tensor is a matrix. A 3D tensor might be an image batch or a sequence of embeddings. The dimensionality is limited only by available memory.
