No output from EmissionsTracker

[coillarach]

• CodeCarbon version: 1.2.0
• Python version: 3.9.15
• Operating System: Ubuntu 18.04.6

Description

I Installed CodeCarbon according to the instructions as part of a JupyterHub setup. The example code worked perfectly with several groups of students, but then the output from the package just stopped. The data was no longer written to the emissions.csv file, and there was no output to the console on calling tracker.stop(). I have exactly the same configuration running locally where it still works fine. I therefore suspect that there is something about the state of the server installation that is causing the problem. My question is, under what circumstances would this behaviour be expected? That would help me track down the problem. From the CodeCarbon point of view, the issue is that there is no error message to say what has failed.

What I Did

Installed TLJH: https://tljh.jupyter.org/en/latest/install/index.html
Installed required packages including CodeCarbon
Prepared and tested the notebook which worked perfectly using the examples: https://mlco2.github.io/codecarbon/examples.html
Ran the same session for several groups of roughly 20 students - everything was fine for the first three groups, but on the fourth, EmissionsTracker.stop() returned no output and nothing was written to emissions.csv

I have reduced the number of configured users and reduced the volume of files to free up disk space. Neither of these actions worked.
I have also restarted the TLJH server and reinstalled CodeCarbon but the behaviour is the same.

from codecarbon import EmissionsTracker
import timeit
tracker = EmissionsTracker()
tracker.start()
t1 = timeit.timeit(stmt='[random.randint(0, 1000) for r in range(10000)]', 
              setup='import random', 
              number=1000
             )
tracker.stop()

Thanks for reporting this. Did you see the log anywhere ?

FYI using CodeCarbon multiple time on the same server at the same time will report wrong result as it will compute the server footprint for each notebook, not only the notebook running it. We are working on #316 for that.

Hi Benoit Thanks for getting back to me so quickly. I haven’t seen a logfile other than the emissions.csv – can you suggest where to look or what the name of the logfile might be? I have checked the notebook working directory but there is nothing there.

Hi Brian,
I just do a test on a new project in TLJH and I saw the log in the Notebook:

jupyter-lab --version 3.5.3
jupyterhub --version 1.4.0

Hi Benoit I don’t get that much log output: [Graphical user interface, text, application Description automatically generated] Is there a ‘verbose’ setting that I can enable?

You could add file logging this way:

tracker = EmissionsTracker()

# logger customization must be done after EmissionsTracker() because it reset all the log handlers.
set_logger_level(logging.DEBUG)
# create file handler which logs even debug messages
fh = logging.FileHandler("codecarbon.log")
fh.setLevel(logging.DEBUG)
formatter = logging.Formatter(
    "%(asctime)s - %(name)-12s: %(levelname)-8s %(message)s"
)
fh.setFormatter(formatter)
logger.addHandler(fh)
logger.debug("DEBUG TEST")
logger.info("INFO TEST")
logger.warning("warning TEST")

tracker.start()

You will get a file codecarbon.log in the notebook folder. It won't capture the initialization, that's our fault : one more issue.

Hi Benoit Thanks for the logging code. However, when I tried it, everything worked as normal – the problem had vanished! As far as I know, nothing has changed since the last time I tried and there was no output. I don’t think it’s the logging code that has resolved the issue because I tried restarting the kernel and running the original code again without logging, and again it worked perfectly. I guess I will just have to wait until the problem re-occurs and then try looking at the debug output. I’ll keep you updated.
