[tvmc] Introduce 'run' subcommand (part 4/4) #6578

leandron · 2020-09-28T16:21:13Z

Introduces the tvmc run subcommand on tvmc, the aims to enable execution of compiled modules using tvmc compile:

Include options to locally or remotelly using RPC
Include support to cpu and gpu devices
Introduces a new function to parse RPC command line strings (will be backported to tvmc tune in a future PR)

something went wrong with CI. Retriggering it now

python/tvm/driver/tvmc/runner.py

+        action="store_true",
+        help="generate profiling data from the runtime execution. "
+        "Using --profile requires the Graph Runtime Debug enabled on TVM. "
+        "Profiling may also have an impact on inference time, "


I am a little curious about this sentence. As far as I know, debug graph runtime is just to record op execution time, no other debug flags to add to build tvm(like -g). So how does it affect the inference time?

Even running debug runtime would affect the inference time compared to the graph runtime.

That is a good question. @comaniac can you comment? Maybe this needs some rephrasing?

Yeah I'm just saying the overhead of collecting/dumping op execution time.

However, this overhead shouldn’t affect the inferece time in my opinion. Because we record this using chrono, when we dump, the time is recorded completely and shouldn’t affect our record.

If we want to describle the overhead, maybe we shouldn’t use the inference time and to say we will introduce the overload time of collecting / dumping which will make our pipiline longer than before.

IMO this CLI is facing to end-users more than the developers, so I supposed they care the end-to-end time more than just the inference time. However, I agree with you that rephrasing the description to avoid inference time might be more accurate.

OHTH, given that this PR is in the list of 0.7 release, would you mind letting the PR in first and fix this issue in the follow-up PR along with other TODOs, since the CI takes a long time?

Yeah, of course.

+    assert len(sut[1]) == expected_number_of_results_per_line
+
+
+def test_run_tflite_module__with_profile__valid_input(


why there are many function names using double underscore?

This is used on other test cases, mostly to mark separation of sentences. I can revert it back in case it looks too wrong, but for me they are very useful when reading it in a long list of tests with similar names and slightly different conditions.

I suggest we keeping the style like all other test. Current function names are like generated by automatic tools. How about this suggestion?

FrozenGene

Overal LGTM. But we should complete other TODOs in the following prs as this tool is very critial and maybe the most important end userface developers use TVM in the future.
