Vector indexing is also supported but care must be taken regarding performance as, in general its much less performant than slice based indexing. Note: Starting from version 0.5.0, vector indexing in torch follows R semantics, prior to that the behavior was similar to numpy’s advanced indexing. bull wynne dealership
