MLTracker: Lightweight Machine Learning Experiment Tracker

MLTracker is a lightweight library for tracking machine learning experiments, models and metrics. It is a simple data model built on TinyDB. I create this for personal use but feel free to use it as you want.

Installation

pip install mltracker

Usage

Create an Experiment

from mltracker import getExperiment

experiment = getExperiment("my-experiment") # get or creates an experiment
print(experiment.id, experiment.name)

Add a model to track:

model = experiment.models.create(hash="123456", name="model1")
model.modules.add(name="conv_layer", attributes={"type": "conv", "layers": 3})
model.modules.add(name="actv_layer", attributes={"type": "relu"})
model.modules.add(name="linear_layer", attributes={"in_size": 256, "out_size": 10})

Track metrics:

model.metrics.add(name="accuracy", value=0.85, epoch=1, phase="train")
model.metrics.add(name="loss", value=0.25, epoch=1, phase="train") 
model.metrics.add(name="accuracy", value=0.87, epoch=1, phase="test")
model.metrics.add(name="loss", value=0.24, epoch=1, phase="test")
model.epoch += 1

model.metrics.add(name="accuracy", value=0.89, epoch=2, phase="train")
model.metrics.add(name="loss", value=0.29, epoch=2, phase="train")
model.metrics.add(name="accuracy", value=0.88, epoch=2, phase="test")
model.metrics.add(name="loss", value=0.26, epoch=2, phase="test")
model.epoch += 1

Track extra metadata:

iteration = model.iterations.create(epoch=2)
iteration.modules.add(name="SGD", attributes={"lr"=0.01})

Then just retrieve what you need.

model = experiment.models.read(hash="123456")
print(model.epoch)

for module in model.modules.list():
    print(module.name, module.attributes)

for metric in model.metrics.list(): 
    print(metric.name, metric.value)
