   @kevinthesun Any timeframe?
   Off topic, I want to mention TensorRT supports dynamic shape from 7.0. To provide better
performance, it supports multiple optimization profiles for different shape range. Say your
input is 1d ranged from 1 to 1024. You can create profiles whatever shape you specified, overlap
or non-overlap, e.g.
   (1, 8, 16)    -> this profile is valid for 1 to 16, specifically optimized of 8 
   (16, 24, 32)
   (33, 48, 63)
   Users can manually select profile to use. In terms of
I have some questions, `Representing Dynamism` is solved by shape function, but how do I manually
represent a constrained dynamism? That is our input is only valid from 1 to 1024 or 16 to
   This dynamic shape may be n-d varying, how do you want to handle overlapping (in this case,
