sxjscience opened a new issue #17823: [Operator] Add `index_add` or `index_update` to numpy extension URL: https://github.com/apache/incubator-mxnet/issues/17823 We need the functionality to calculate `b = index_add(a, indices, value)`, which mimics the outcome of `a[indices] += value`. This is similar to the `tensor_scatter_nd_add` in TF: https://www.tensorflow.org/api_docs/python/tf/tensor_scatter_nd_add Also in JAX: https://jax.readthedocs.io/en/latest/_autosummary/jax.ops.index_update.html#jax.ops.index_update
