Simple logging of statistics, model checkpoints, plots and other objects for your Machine Learning Experiments (MLE). Furthermore, the MLELogger comes with smooth multi-seed result aggregation and combination of multi-configuration runs. For a quickstart check out the notebook blog 🚀
from mle_logging import MLELogger
# Instantiate logging to experiment_dir
log = MLELogger(time_to_track=['num_updates', 'num_epochs'],
what_to_track=['train_loss', 'test_loss'],
experiment_dir="experiment_dir/",
model_type='torch')
time_tic = {'num_updates': 10, 'num_epochs': 1}
stats_tic = {'train_loss': 0.1234, 'test_loss': 0.1235}
# Update the log with collected data & save it to .hdf5
log.update(time_tic, stats_tic)
log.save()You can also log model checkpoints, matplotlib figures and other .pkl compatible objects.
# Save a model (torch, tensorflow, sklearn, jax, numpy)
import torchvision.models as models
model = models.resnet18()
log.save_model(model)
# Save a matplotlib figure as .png
fig, ax = plt.subplots()
log.save_plot(fig)
# You can also save (somewhat) arbitrary objects .pkl
some_dict = {"hi" : "there"}
log.save_extra(some_dict)Or do everything in a single line...
log.update(time_tic, stats_tic, model, fig, extra, save=True)
The MLELogger will create a nested directory, which looks as follows:
experiment_dir
├── extra: Stores saved .pkl object files
├── figures: Stores saved .png figures
├── logs: Stores .hdf5 log files (meta, stats, time)
├── models: Stores different model checkpoints
├── init: Stores initial checkpoint
├── final: Stores most recent checkpoint
├── every_k: Stores every k-th checkpoint provided in update
├── top_k: Stores portfolio of top-k checkpoints based on performance
├── tboards: Stores tensorboards for model checkpointing
├── <config_name>.json: Copy of configuration file (if provided)
For visualization and post-processing load the results via
from mle_logging import load_log
log_out = load_log("experiment_dir/")
# The results can be accessed via meta, stats and time keys
# >>> log_out.meta.keys()
# odict_keys(['experiment_dir', 'extra_storage_paths', 'fig_storage_paths', 'log_paths', 'model_ckpt', 'model_type'])
# >>> log_out.stats.keys()
# odict_keys(['test_loss', 'train_loss'])
# >>> log_out.time.keys()
# odict_keys(['time', 'num_epochs', 'num_updates', 'time_elapsed'])If an experiment was aborted, you can reload and continue the previous run via the reload=True option:
log = MLELogger(time_to_track=['num_updates', 'num_epochs'],
what_to_track=['train_loss', 'test_loss'],
experiment_dir="experiment_dir/",
model_type='torch',
reload=True)A PyPI installation is available via:
pip install mle-logging

# Provide all configuration details as option
log = MLELogger(time_to_track=['num_updates', 'num_epochs'],
what_to_track=['train_loss', 'test_loss'],
