[GRASS-web] GRASS i.segment

Tue May 11 18:51:41 PDT 2021

Hi Guy,

The option #1 is still available to you as far as I can tell. You can
actually use Docker images with AWS Lambda and that was introduced exactly
to solve dependency issues. The images can be in GBs. That's quite
sufficient for GRASS GIS, its dependencies, and any other Python packages
you need. Adding other Python packages which your code needs should not be
a problem.

With that said, #2, i.e., pip or conda installation would be still helpful
in many cases including yours (although there would still be a few hurdles
before putting it on the old container-free AWS Lambda). Same goes for
minimizing the build (like including only components necessary for
i.segment). Seemingly unrelated, but CMake build support (now as a
prototype) may be a step towards better packaging. Anyway, this would be
all optional if you go with #1.

I would also add item #3 which is something I suggested earlier. You did
not mention it explicitly, but it seems to me that your workflow would
benefit from an API oriented on execution of a single module. Although
that's certainly possible, a different API may provide a smoother
experience in these cases. This does not replace #1 or #2, but it is
complementary.

I have cc-ed the grass-dev mailing list which is what the developers are
following more closely. The best way is, however, to subscribe to that list
and post your goal, possibly with some of my points, there with "funding
available" included in the subject.

Best,
