Tensorboard is showing no data

[SExpert12]

Hello,

I am running the PPO algorithm of Ray RL lib. When I run the code the screen is like this:

So I feel that model is getting trained. Later when I start to visualization using tensorboard I got this screen:

So I check the ray result folder and I see that these files are generated:

But when I insect the data the results is like this:

What is going on here?

Is the model is getting trained or not? Why no data is showing and how to get the data?

Please I need a help as this the last step I am stuck from days..

Can you please provide more information about what you are doing? TensorBoard has nothing to do with Ray RL lib so it's hard to say whether events are being written correctly but if you upload your logdir I'd be happy to take a look.

Sure. I am trying to train a vehicle based on ray library algorithm in CARLA simulator.

This is my log file.

Please tell me if you need any other information. Thanks you so much for your help.

There doesn't seem to be any events written to your events file (you can even see the file is only 25 bytes). I'm not sure what's going on here, but it doesn't seem like your model is being trained.

Okay. Thanks. Do I need to include the summary writer explicitly in my code to view data in Tensorboard. I am using ray rllib to train model.

Thanks for your help.

Probably? I really have no idea how rllib works as we have no relationship with them.
