########## File path: python/mxnet/numpy/multiarray.py ########## @@ -720,6 +720,28 @@ def __getitem__(self, key): key = (_np.newaxis,) + key return self._get_np_basic_indexing(key) elif indexing_dispatch_code == _NDARRAY_ADVANCED_INDEXING: + if prepend == _NDARRAY_NO_ZERO_DIM_BOOL_ARRAY and isinstance(key, (NDArray, _np.ndarray)): Review comment: The `isinstance(key, (NDArray, _np.ndarray)` check here would be equivalent to the `isinstance(key, Symbol)` check in https://github.com/apache/incubator-mxnet/pull/18319/files#diff-e9b526dba36aa6f2e7dbb6c4d49e9822R159-R160 ? Can you elaborate why you call the `self._get_index_nd` here instead of directly calling `_npi.advanced_indexing(self, key)` as in the Symbol case? Is it due to `indexing_key_expand_implicit_axes` above? Should the check if `_npi.advanced_indexing` can be called (and if possible, calling `_npi.advanced_indexing`) be done before `indexing_key_expand_implicit_axes` is called above? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
