Using NNI with nn-Meter

[singagan]

Hi, seems like your ProxylessNAS example is not supported by NNI anymore as they have moved to a completely different backend (instead of retiarri). Please, do you have an updated example that works with the newer version?

Thanks.

Thanks for raising this issue. Here is the latest version of Hardware-aware NAS, and nn-meter performs as a (profiler)[https://nni.readthedocs.io/en/latest/reference/nas.html#nni.nas.profiler.pytorch.nn_meter.NnMeterProfiler] in new architecture. You can try newer versions of NnMeterProfiler now. Notice that you should use the dev version of nn-Meter and NNI.

Thanks.

Thanks a lot! I have two questions:

1. Is it possible to add multiple objectives like both latency (using nn-meter) and model size which doing search with ProxylessNAS?
2. Is there a significant difference between the new nni architecture and retiarrii for HW-aware NAS?

Hi, thanks for your interests to NNI and nn-Meter. Let me defer to my colleague as the main maintainer of NNI NAS module to answer these questions. Yuge Zhang (@ultmaster) Thanks a lot Yuge!

1. You need a new (probably custom defined profiler).
2. NNI NAS 3.0 is an upgraded version of Retiarii NAS. The old version is out-of-date and won't be maintained any more.
