WebNov 5, 2024 · In fact, we did switch to the HybridSequential model and hybridized it when we tested on MXNet 0.12. And it could very well be why we managed to get to batch sizes up to 1000 (and not because of 0.12 upgrade). But we are still way behind Keras/Tensorflow where we could scale to batch sizes of up to 15000.
