A simple yet powerful tensorboard event log parser/reader.

* Supports parsing tensorboard event [scalars][parsing-scalars], [tensors][parsing-tensors], [histograms][parsing-histograms], [images][parsing-images], [audio][parsing-audio], [hparams][parsing-hparams], and [text][parsing-text].
* Supports event generated by
  [PyTorch](https://pytorch.org/docs/stable/tensorboard.html), [Tensorboard/Keras](https://www.tensorflow.org/tensorboard), and [TensorboardX](https://github.com/lanpa/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](https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html) to allow advanced filtering.
* Both the documentation and code have high test coverage rate.
* Follows [PEP 484](https://www.python.org/dev/peps/pep-0484/) with full type hints.

Installation:

```sh
pip install -U tbparse # requires Python >= 3.8
```

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:

```py
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:

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

## Installation

```sh
pip install tensorflow # optional, only required if you want to parse images and audio
pip install -U tbparse # requires Python >= 3.8
```

**Note**: For details on when TensorFlow is required, see [Installing without TensorFlow](https://tbparse.readthedocs.io/en/latest/pages/installation.html#installing-without-tensorflow).

## Testing the Source Code

Test source code:

```sh
python3 -m pip install tox
python3 -m tox
```

Test and build documentation:

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

Generate test coverage:

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