2022-B : Energy and Performance tracking with Tensorflow
Using Tensorflow and Tensorboard
TODO add usage for tensorflow and tensorboard to ensure users have their code setup in the correct format
Energy Callback Python Package
Install the python package for generating the callback function
$pip install energy-callback
Usage
Import the package, please first ensure the packages tensorflow and energy-monitor are installed as these are requirments for the package.
import energy_callback
Create a callback object
callback = energy_callback.Callback()
Args:
- country (str): Country for estimating gCO2e per kWh Default: 'United Kingdom'
- csv_path (str): Filepath to csv file to log results. Default: './tb_experiment_1.csv'
For example to change the country to France and the csv path to 'my_csv.csv':
callback = energy_callback.Callback('France', 'my_csv.csv')
Input the callback object into the model.fit function
history = model.fit(x=x_train,
y=y_train,
epochs=5,
validation_data=(x_test, y_test),
callbacks=[tensorboard_callback, callback])
Use callback.get_csv() to generate csv containing performance and energy values for each epoch of training. Make sure to pass in the history value from model.fit to include the tensorboard model performance metrics in the csv. Default csv filepath is 'tb_experiment_1.csv'
callback.get_csv(history)
Energy Calculations
The package will check if it can access the intel-rapl directory and use the values here for calculating joules otherwise it will use the python-energy-monitor package
To estimate the co2e value the tracker uses the carbon intensity for the given country and uses the corresponding gco2/kWh value from here https://ourworldindata.org/grapher/carbon-intensity-electricity The default value is United Kingdom.
Using RAPL energy readings
Due to a security issue all Linux distributions are changing the permisions of the RAPL files used by the raplMonitor in this package. There is a workaround for this:
sudo apt install sysfsutils
- Add this line in
etc/sysfs.conf
:mode class/powercap/intel-rapl:0/ = 0444
reboot
Or to temporarily change the permission (will reset on reboot) sudo chmod -R a+r /sys/class/powercap/intel-rapl
