SheepRL Dreamer v3 - ValueError

[ogulcankertmen]

I tried; "sheeprl exp=dreamer_v3 env=gym env.id=CartPole-v1" this one and i got "ValueError:
you tried to log -1 which is currently not supported. Try a dict or a scalar/tensor.

Set the environment variable HYDRA_FULL_ERROR=1 for a complete stack trace." these results. And I couldn't solve this problem. Do you have any suggestions?

Hi @ogulcankertmen, I've tried the exact same command on the main branch on my machine and the training goes well: can you please share more info about the error? Maybe the entire stacktrace?

@belerico Here is the stacktrace;

Hi @ogulcankertmen, I've tried on my windows machine and nothing happens: I'm not able to replicate.
Could you please share also your env?
I've seen from your error that the log_dir path has mixed separators: I've created a branch where we normalize the separators on windows. Can you try it?
Also: why torch tensorboard is calling tensorflow to create the logdirs?
I'm referring to this line:

  File "C:\Users\Oğulcan\AppData\Local\Programs\Python\Python311\Lib\site-packages\torch\utils\tensorboard\writer.py", line 75, in __init__
    self.event_writer = EventFileWriter(

    tf.io.gfile.makedirs(logdir)
  File "C:\Users\Oğulcan\AppData\Local\Programs\Python\Python311\Lib\site-packages\tensorflow\python\lib\io\file_io.py", line 513, in recursive_create_dir_v2
    _pywrap_file_io.RecursivelyCreateDir(compat.path_to_bytes(path))

What happens if you remove tensorflow?
