|
* @param x The input tensor whose slices are to be gathered.
|
* @param indices The indices of the values to extract.
|
* @param axis The axis over which to select values. Defaults to 0.

* than or equal to rank(indices). Defaults to 0.
|
* The output tensor will have shape of
|
* `x.shape[:axis] + indices.shape[batchDims:] + x.shape[axis + 1:]`
