Review comment:
       I guess there is no need to change the `auto`, `auto` seems to be a good way to prevent
implicit type casting (sometime developer us could be careless). The only problem of `auto`
is just the code readability for the developer to know the exact datatype.
   In any case, I think need to keep the same version of complier between the docker version
and conda version (as in #759), because a few day ago we had the similar complier error because
of the version different.
