tensorforce: Adding a summarizer results in a NotFoundError

I haven’t been able to add a summarizer to my PPO Agent object. The settings I used are (although I did try other configurations without success):

summarizer=dict(
    directory='./logs-tensorboard',
    steps=50,
    labels=['losses']            
)

And running this results in the following error:

tensorflow.python.framework.errors_impl.NotFoundError: Resource localhost/logdir:./logs-tensorboard/class tensorflow::SummaryWriterInterface does not exist.

Maybe this is related to https://github.com/reinforceio/tensorforce/issues/415, although I did not test my code with a tensorforce version prior to the fix for that issue. This might also just be something I missed from the documentation!

I’ve had a similar issue. Adding 'graph' to the labels solved it, i.e.

summarizer=dict(
    directory='./logs-tensorboard',
    steps=50,
    labels=['graph', 'losses']
)

Summaries work with the new branch (major-revision), which will be merged with master soon, hence already closing summary-related issues. Currently supported labels:

"bernoulli", "beta", "categorical", "distributions", "dropout", "entropy", "gaussian", "graph",
"loss", "losses", "objective-loss", "regularization-loss", "relu", "updates", "variables"

Others will be added, and please feel free to post specific requests here.
