ZheyuYe opened a new issue #17327: np.ndarray indexing after hybridize URL: https://github.com/apache/incubator-mxnet/issues/17327 ## Description Indexing is an important feature of numpy that supports complex positioning and value operations as [Numpy | Indexing](https://www.geeksforgeeks.org/numpy-indexing/). The mxnet deepnumpy only supply the basic indexing operation as ``` gathered_data = sequence[indices_x, indices_y] ``` whereas the above operation will fail after hybridize, see [here](https://github.com/apache/incubator-mxnet/pull/16621). Currently, the more effective method is only [mx.npx.pick](https://numpy.mxnet.io/api/deepnumpy/generated/mxnet.npx.pick.html), but it only supports one-dimensional selection instead of providing gather_nd operation( for nd.ndarray) can select array elements multidimensionally. The temporary solution would be adding the gather_nd operation for mx.np.ndarray, and the hybridized indexing opertaion could be added in future work. @sxjscience @haojin2
