The Eco2AI is a python library for CO2 emission tracking. It monitors energy consumption of CPU & GPU devices and estimates equivalent carbon emissions taking into account the regional emission coefficient. The Eco2AI is applicable to all python scripts and all you need is to add the couple of strings to your code. All emissions data and information about your devices are recorded in a local file.
Every single run of Tracker() accompanies by a session description added to the log file, including the following elements:
- project_name
- experiment_description
- start_time
- duration(s)
- power_consumption(kWTh)
- CO2_emissions(kg)
- CPU_name
- GPU_name
- OS
- country
To install the eco2AI library, run the following command:
pip install eco2ai
Example usage eco2AI 
The eco2AI interface is quite simple. Here is the simplest usage example:
import eco2ai
tracker = eco2ai.Tracker(project_name="YourProjectName", experiment_description="training the <your model> model")
tracker.start()
<your gpu &(or) cpu calculations>
tracker.stop()The eco2AI also supports decorators. As soon as the decorated function is executed, the information about the emissions will be written to the emission.csv file:
from eco2ai import track
@track
def train_func(model, dataset, optimizer, epochs):
...
train_func(your_model, your_dataset, your_optimizer, your_epochs)For your convenience, every time you instantiate the Tracker object with your custom parameters, these settings will be saved until the library is deleted. Each new tracker will be created with your custom settings (if you create a tracker with new parameters, they will be saved instead of the old ones). For example:
import eco2ai
tracker = eco2ai.Tracker(
project_name="YourProjectName",
experiment_description="training <your model> model",
file_name="emission.csv"
)
tracker.start()
<your gpu &(or) cpu calculations>
tracker.stop()
...
# now, we want to create a new tracker for new calculations
tracker = eco2ai.Tracker()
# now, it's equivalent to:
# tracker = eco2ai.Tracker(
# project_name="YourProjectName",
# experiment_description="training the <your model> model",
# file_name="emission.csv"
# )
tracker.start()
<your gpu &(or) cpu calculations>
tracker.stop()You can also set parameters using the set_params() function, as in the example below:
from eco2ai import set_params, Tracker
set_params(
project_name="My_default_project_name",
experiment_description="We trained...",
file_name="my_emission_file.csv"
)
tracker = Tracker()
# now, it's equivelent to:
# tracker = Tracker(
# project_name="My_default_project_name",
# experiment_description="We trained...",
# file_name="my_emission_file.csv"
# )
tracker.start()
<your code>
tracker.stop()If for some reasons it is not possible to define country, then emission coefficient is set to 436.529kg/MWh, which is global average. Global Electricity Review
For proper calculation of gpu and cpu power consumption, you should create a "Tracker" before any gpu or CPU usage.
Create a new “Tracker” for every new calculation.
An example of using the library is given in the publication. It the paper we presented experiments of tracking equivalent CO2 emissions using eco2AI while training ruDALL-E models with with 1.3 billion (Malevich, ruDALL-E XL 1.3B) and 12 billion parameters (Kandinsky, ruDALL-E XL 12B). These are multimodal pre-trained transformers that learn the conditional distribution of images with by some string of text capable of generating arbitrary images from a russian text prompt that describes the desired result. Properly accounted carbon emissions and power consumption Malevich and Kandinsky fine-tuning Malevich and Kandinsky on the Emojis dataset is given in the table below.
| Model | Train time | Power, kWh | CO2, kg | GPU | CPU | Batch Size |
|---|---|---|---|---|---|---|
| Malevich | 4h 19m | 1.37 | 0.33 | A100 Graphics, 1 | AMD EPYC 7742 64-Core | 4 |
| Kandinsky | 9h 45m | 24.50 | 5.89 | A100 Graphics, 8 | AMD EPYC 7742 64-Core | 12 |
Also we presented results for training of Malevich with optimized variation of GELU activation function. Training of the Malevich with the 8-bit version of GELU allows us to spent about 10% less energy and, consequently, produce less equivalent CO2 emissions.
