tbparse

A simple yet powerful tensorboard event log parser/reader.

• Supports parsing tensorboard event scalars, tensors, histograms, images, audio, hparams, and text.
• Supports event generated by PyTorch, Tensorboard/Keras, and TensorboardX, with their respective usage examples documented in detail.
• Allows parsing multiple tensorboard event files in a hierarchical directory structure.
• Provides plotting examples for each type of events.
• Stores the data in pandas.DataFrame to allow advanced filtering.
• Both the documentation and code have high test coverage rate.
• Follows PEP 484 with full type hints.

Installation:

pip install tensorflow # or tensorflow-cpu
pip install -U tbparse # requires Python >= 3.7

Note: If you don't want to install TensorFlow, see Installing without TensorFlow.

We suggest using an additional virtual environment for parsing and plotting the tensorboard events. So no worries if your training code uses Python 3.6 or older versions.

Reading one or more event files with tbparse only requires 5 lines of code:

from tbparse import SummaryReader
log_dir = "<PATH_TO_EVENT_FILE_OR_DIRECTORY>"
reader = SummaryReader(log_dir)
df = reader.scalars
print(df)

If you want an additional column with directory names (i.e., run names), change line 3 above to the following:

reader = SummaryReader(log_dir, extra_columns={'dir_name'})

For further information, start from the page: Parsing Scalars.

Testing the Source Code

Test source code:

python3 -m pip install tox
python3 -m tox

Test and build documentation:

cd docs
make clean
# sphinx-tabs seems to require html be built before doctest
make html
make doctest

Generate test coverage:

python3 -m pip install pandas tensorflow torch tensorboardX pytest pytest-cov
python3 -m pytest --cov=./ --cov-report html
