Web22 hours ago · This prevents us from using libraries like NumPy or PyTorch, which only support fixed shapes. To efficiently buffer samples, enn-trainer uses a Rust implementation of 3D ragged arrays which support variable sequence lengths in the second dimension. This allows the sample buffer to contain an arbitrary number of entities at every time step. WebRagged arrays are the core data structures in k2, designed by us independently.
