TensorBoard is a suite of web applications for inspecting and understanding your TensorFlow runs and graphs. Before running TensorBoard, make sure you have generated summary data in a log directory by creating a SummaryWriter:
# sess.graph_def is the graph definition. summary_writer = tf.train.SummaryWriter('/path/to/logs', sess.graph_def)
For more details, see this tutorial. Then run TensorBoard and provide the log directory:
python tensorflow/tensorboard/tensorboard.py --logdir=path/to/logs # or if installed via pip, run: tensorboard --logdir=path/to/logs # if building from source bazel build tensorflow/tensorboard:tensorboard ./bazel-bin/tensorflow/tensorboard/tensorboard --logdir=path/to/logs # then connect to http://localhost:6006
Note that TensorBoard requires a logdir to read logs from. For info on configuring TensorBoard, run tensorboard --help.
TensorBoard includes a backend (tensorboard.py) that reads TensorFlow event data from the tfevents files, and then serves this data to the browser. It also includes a frontend (app/tf-tensorboard.html) that contains html and javascript for displaying this data in a UI.
The following instructions are useful if you want to develop the TensorBoard frontend in a lightweight frontend-only environment. It sets up gulp with automatic recompiling and serves just the frontend assets without a connected backend.
If you just want to use TensorBoard, there is no need to read any further.
Get nodejs and npm through whatever package distribution system is appropriate for your machine. For example, on Ubuntu 14.04, run sudo apt-get install nodejs nodejs-legacy npm. Then, run sudo npm install -g gulp bower tsd.
Inside this directory (tensorflow/tensorboard), run the following commands.
npm install bower install tsd install
Inside this directory, run gulp. That will compile all of the html/js/css dependencies for TensorBoard, and also spin up a server (by default at port 8000). You can navigate to component-specific demo pages to check out their behavior.
Running gulp test will run all unit tests, the linter, etc.
