Subject Re: [apache/incubator-mxnet] [RFC] Deferred compute in imperative interface to unify imperative and symbolic interface (#16376)
Date Tue, 28 Jan 2020 04:43:06 GMT
This seems to be a big change to the existing operator mode (imperative and symbolic). Could
you please provide more information.

AFAIK, symbolic API already does deferred init, imperative API is provided to improve user
experience. Based on this RFC, what's the advantage of this new deferred_compute mode? As
a user, when should I use it or not.

Another question. We all know deferred init cause bad user experience when it comes to debugging.
Would this RFC address the debuggability issue?

If it's about performance optimization, could we have some initial data of using this new
deferred mode vs. existing imperative mode?
