[INFO] Solving using legacy API

Bathsheba · September 2, 2022, 12:00am

Flask always gives a message like
[INFO] Solving using legacy API: <HopsComponent /nca [seed,steps -> NCA -> nstep,colors]
Is there a more current API that I haven’t discovered?

Thanks

What does your url look like in your hops component?

That is coming from here in the ghhops server code

github.com

mcneel/compute.rhino3d/blob/master/src/ghhops-server-py/ghhops_server/base.py#L60


      
              return False, self._return_with_err("Nothing to solve on root")
          
          
# FIXME: remove support for legacy solve behaviour
          elif uri == "/solve":
              data = json.loads(payload)
              comp_uri = data["pointer"]
              if not comp_uri.startswith("/"):
                  comp_uri = "/" + comp_uri
              for comp in self._components.values():
                  if comp_uri == comp.uri:
                      hlogger.info("Solving using legacy API: %s", comp)
                      return self._process_solve_request(comp, payload)
          
          
# FIXME: test this new api
          else:
              comp = self._components.get(uri, None)
              if comp:
                  hlogger.info("Solving: %s", comp)
                  return self._process_solve_request(comp, payload)
          return False, self._return_with_err("Unknown Hops component url")

My hops path is http://127.0.0.1:6058/nca , I copied the url from the Flask output as in the Connecting Hops to CPython video.
Is there later documentation I should be looking at?

I’m not exactly sure. It doesn’t look like one technique really works any better than another. @eirannejad do you remember what we were trying to do here?

Hi Steve,

Suddenly, I have the same issue
[INFO] Solving using legacy API: …

and the hops become super slow. I have tried to restart my computer, but still not going anywhere.

I used Hops 0.15.5

We’ll need some more details to be able to help.
