projector
 ```
 
 Notes:
 
 - to see the projector in a local tensorboard instance, you have to point the `--logdir` argument specifically to the `logs/imdb-example` directory, as tensorboard does not succeed in looking for projector data recursively as it does for scalar data with `--logdir .`.
 - `tensorflow` must be installed, or the projector plugin will not be able to load these data.
