setup_carbon_tracker() installs codecarbon into a
dedicated r-codecarbon conda environment, with
confirmation.carbon_tracker() wraps a codecarbon
OfflineEmissionsTracker with
$start()/$stop()/$flush()
methods.with_emissions_tracked() measures a single block of
code in one call.list_carbon_tracker_countries() lists supported
country_iso_code values.carbon_tracker_ready() checks whether codecarbon is
installed and importable.carbon_tracker()/with_emissions_tracked()
now create output_dir if it doesn’t already exist, instead
of crashing at $stop() after the tracked code has already
run.setup_carbon_tracker() installs codecarbon
>= 2.2.2 – a floor, not an exact pin (see
?setup_carbon_tracker for why). Versions actually validated
against so far:
tests/testthat/test-tracker.R’s tracker-restart regression
test confirmed against this version directly).R CMD check + testthat),
and directly against the tracker-restart behavior in an isolated
environment. Tracker-restart behavior differs from 2.2.2 (see Known
limitations below) but CodeCarbonR’s own tests pass against both.If you validate against a different version (e.g. a Monsoon HPC run), add it to this list rather than replacing what’s here – the point is an honest record of what’s actually been checked, not just the most recent.
carbon_tracker() instance
($start() after a prior $stop()) does not
produce an independent measurement for the new phase – codecarbon’s
underlying tracker never resets its internal clock on
stop(). What that produces downstream is
codecarbon-version- dependent (frozen stale reading on 2.2.2, inflated
cumulative reading on 3.3.0 – see the “codecarbon version compatibility”
section above), but it’s never a clean isolated measurement either way.
Use a separate carbon_tracker() per phase instead. See
?carbon_tracker.comparison/07_gpu_neural_net) is
implemented but not yet validated on real GPU hardware.R CMD check/testthat on both via GitHub
Actions CI, but the comparison suite (cases 01-06) has only been
rendered end to end on Windows so far. CI passing is a package-level
signal, not evidence that the comparison suite’s accuracy validation
holds on those platforms – don’t cite this as cross-platform accuracy
validation without an actual comparison-suite render on Mac/Linux.See comparison/coverage_matrix.md for full validation
status per test case and platform.
