formath commented on issue #7934: Bug of group2ctx? Wrong device placement? URL: https://github.com/apache/incubator-mxnet/issues/7934#issuecomment-330742175 During `PlaceDevice`, if an `op` can't be assigned a device id, its device id will be set `0`. And to assign a default context is done after `PlaceDevice`, so it will not works actually. `0` indicates which context depends on the `group2ctx`. More deeply, it is the index when traversing a map, so alphabetical. It is should be a bug. @tqchen @piiswrong ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
