Tensorflow not found

[jajawunderbar]

Why I get this by using the docker command Its installed by pip and tried docker
also. Thanks. Mathias

Hi thanks for reaching out! Which commands are you using and what are the error messages that you get?

[jajawunderbar]

docker run -it --rm -p 8000:8000 arpllab/learning_to_fly

Waiting for Tensorboard
TensorFlow installation not found - running with reduced feature set.

NOTE: Using experimental fast data loading logic. To disable, pass
"--load_fast=false" and report issues on GitHub. More details:

TensorBoard 2.12.2 at http://b1d7ad5cd59a:6006/ (Press CTRL+C to quit)
Running command:

but no web interface after that.

This

TensorFlow installation not found - running with reduced feature set.

is no problem and expected. Tensorboard (which is only used to visualize the training logs) tries to load TensorFlow but it is not required. It is just part of the Docker image but not used in this example.

When you go to http://0.0.0.0:8000/ with your web-browser after it shows:

Web interface coming up at: http://0.0.0.0:8000/

is the simulator UI showing up?

If you want to try Tensorboard you can use

docker run -it --rm -p 6006:6006 arpllab/learning_to_fly training_headless

as described in the readme

You should be able to view Tensorboard at http://0.0.0.0:6006

[jajawunderbar]

yes, site not reachable.

[jonas-eschmann]

I just updated my last message with more details. But it is quite weird that it is not reachable for you 🤔

Can you try this to see if it is a problem with the docker setup:

docker run -it --rm -p 8000:8000 python python -m http.server

[jajawunderbar]

docker run -it --rm -p 6006:6006 arpllab/learning_to_fly training_headless
with this its running.

but no web page

[jonas-eschmann]

If you can't see a webpage even with docker run -it --rm -p 8000:8000 python python -m http.server (as a minimal test case) I think there is some issue with your Docker setup (maybe a firewall or something like that?).

[jajawunderbar]

Thank you very much for your help!
But no chance so far, checked the firewall ... I dont know whats my fault
... The headless says this (see below) and endet with no errors and a complete message, but there is noch checkpoint directory after that?!

[jonas-eschmann]

For that you should mount a local checkpoint directory into the container using e.g. -v $(pwd)/checkpoints:/learning_to_fly/checkpoints.

mkdir checkpoints
docker run -it --rm -p 6006:6006 -v $(pwd)/checkpoints:/learning_to_fly/checkpoints arpllab/learning_to_fly training_headless

This creates checkpoints in the local checkpoint dir for me and I can also observe the Tensorboard logs at http://0.0.0.0:6006

[jajawunderbar]

Thanks! Now I have a firmware.

It's not possible do use it in a simulation like webots, right?
