Support PPE profiling for `Local` #340

KantaTamura · 2024-08-22T02:41:13Z

This PR resolves the Local task in #258

Note

To enable tracing, trace=True must be added during Local() initialization (or from_url()).

Sample program to check tracing

import json
import pytorch_pfn_extras as ppe

from pfio.v2 import Local, Path, from_url

@ppe.profiler.record_function("my_tag_2", trace=True)
def my_run2(x):
    pass

def my_run1(x):
    pass

def p():
    tracer = ppe.profiler.get_tracer()

    tracer.clear()
    with ppe.profiler.record("my_tag_1", trace=True):
        my_run1('hoge')

    for i in range(4):
        my_run2("far")

    dir = 0
    fil = 0
    with Local(trace=True) as fs:
        for f in fs.list():
            if fs.isdir(f.strip()):
                dir += 1
                continue
            
            fil += 1
            len(fs.open(f).read())

    print(fil, "files", dir, "dirs")

    dict = tracer.state_dict()
    keys = [event["name"] for event in json.loads(dict["_event_list"])]
    print(keys)

    w = ppe.writing.SimpleWriter(out_dir="")

    # output '['
    tracer.initialize_writer("trace.json", w)
    # output json dump
    tracer.flush("trace.json", w)

p()

output

drawing of the output json file (trace.json) with chrome://tracing is shown below

Can be specified in the `trace` argument when creating a Local() instance.

Overall LGTM. I have one minor suggestion.

We can also place the pytorch-pfn-extras package under the extras_require section by adding new presets (e.g., trace), not only for testing purposes.

Agree. We'd rather add something like trace than adding the dependency to test. PFIO users shall be using profiling without this extra requires and will be installing PFIO with pip install pfio . In that case, PPE won't be installed even though they need it.

k5342 · 2024-08-22T07:15:08Z

@kuenishi Could you take a look? Please let us know if you have any comments on the tag naming rule and the granularity of the tests.

kuenishi

The Python implementation itself looks good, but I have a few request to align with current style and options.

Please don't extend the TestLocal(unittest.TestCase) class. We're slowly moving on from the unitest style, to a more pytest-like style where each test is defined as a single and independent function (sometimes with fixtures or parameterized). Please refer to test_s3.py.

Changed to not use TestLocal(unittest.TestCase).

Currently, foo.txt is generated in the directory where pytest runs, do you want to use a different path? (e.g. /tmp/...)

As we discussed offline, PPE shouldn't be here but tests must be switched in the test code using something like skipif.

Changed to using importorskip() to skip if no ppe.

We may also need to tweak the tox.ini to enable CI testing for the tracing code, which we're adding this PR if we remove PPE from the test section in setup.py:

Offline discussion summary: the code itself looks nice, but the example script at the issue description doesn't provide valid JSON file and I'm not sure how to verify the output JSON(-like) file by loading onto Chrome tracing. After a minimal script to test this patch provided, I'll revisit and retry validation.

kuenishi

Please leave the summary of offline discussion with PPE developer why we don't need complete JSON file and it works fine without it.

kuenishi

Ah, and don't forget to update tox.ini to include trace option as @k5342 pointed out.

KantaTamura · 2024-08-26T06:09:56Z

Offline discussion summary: Chrome Tracing does not require valid json and can be rendered with just initialize_writer() and flush() as in the sample program.

ref. Trace Event Format

When provided as a string to the importer the ] at the end of the JSON Array Format is optional.

KantaTamura · 2024-08-26T06:28:23Z

fix tox.ini and summarized the json output method in the documentation (tips).
