gclient sync failing on `python3 src/content/test/gpu/gpu_tests/mediapipe_update.py`

[Antonio Maiorano]

I am trying to get Chrome built on a new CloudTop Windows machine. When I run gclient sync, during the run hooks, it eventually fails with:

Running hooks:  43% (62/143) mediapipe_integration_testdata

I've tried 'git clean -xdf' in the src directory, then running gclient sync again, but I get the same result. I've tried running 'download_from_google_storage --config' again, but it doesn't change anything.

Sorry you're running into this Antonio. Have you tried:

python3 C:\src\depot_tools\gsutil.py config

Authenticate as your google.com account (I tried chromium.org but it didn't work - was blocked); does that fix the cloud storage download of this file?

If not - please file a P1 bug, include components Infra>Client>Chrome and Internals>GPU>Testing, and cc: me on the bug. Will try to find someone to figure out why there's no access to download that test bundle.

Thanks,

-Ken

Thanks, Ken, I tried the login, but same result (I had already tried that). I opened a bug, as per your suggestion: https://bugs.chromium.org/p/chromium/issues/detail?id=1445094
