WebFirst, the mechanism for VMAP in TensorFlow 2 is different from that in JAX: JAX performs op-by-op batching without compilation, while TensorFlow does not [Good]. We observe that the non-compiled code still runs in a reasonable amount of time since TensorFlow is optimized to have a competitive eager execution when compared to PyTorch, while JAX …
