mxnet throws no errors when binding the wrong context

Question

I wish to see exactly which cpu or gpu my mxnet program is running, so I add a print self._ctx at the source code of executor.py. Then I bind the executor with gup(10), but no error was thrown since I only have one gpu in my computer. Can someone explain this?

Answer 1

You can instantiate a context object for a non-existent GPU. But if you try to use it, it will throw an exception.
