summaries. -
requirement for
demo_graph.py
is tensorboardX>=1.9 and pytorch>=1.2
Tested on anaconda2 / anaconda3, with PyTorch 1.1.0 / torchvision 0.3 / tensorboard 1.13.0
pip install tensorboardX
or build from source:
git clone https://github.com/lanpa/tensorboardX && cd tensorboardX && python setup.py install
You can optionally install crc32c
to speed up saving a large amount of data.
- Run the demo script:
python examples/demo.py
- Use TensorBoard with
tensorboard --logdir runs
(needs to install TensorFlow)
