enable_perfetto

Is there a guide about use "--enable_perfetto" with benchmark_model?
I don't know how to get perfetto info?

Hi @jixiedaima, welcome here. Happy to help you with the following information -

Perfetto for Benchmark Model: https://ai.google.dev/edge/litert/models/measurement

I feel this will also help you for depth understanding -
perfetto sdk tool guidance android page: https://developer.android.com/tools/perfetto

Thanks!

@jixiedaima, here is additional Info: currently to get Perfetto trace information when benchmarking a LiteRT (TFLite) model on android, you don't use an --enable_perfetto flag, instead LiteRT integrates natively with android's - system tracing "Perfetto/Systrace" via system properties.

link ref official doc: https://ai.google.dev/edge/litert/models/measurement#trace_internals_in_android

"Internal events from the LiteRT interpreter of an Android app can be captured by Android tracing tools. They are the same events with Android Trace API, so the captured events from Java/Kotlin code are seen together with LiteRT internal events.

Some examples of events are:

• Operator invocation
• Graph modification by delegate
• Tensor allocation

Among different options for capturing traces, this guide covers the Android Studio CPU Profiler and the System Tracing app. Refer to Perfetto command-line tool or Systrace command-line tool for other options."

Thanks.
