OpenAI InvalidRequestError during Trajectory Generation

[helen9975]

Thanks for the great work and thorough documentation! I had a question regarding trajectory generation of specific tasks.

When trying to generate trajectories using the following line, there appears to be OpenAI inference errors: python scalingup/inference.py evaluation.num_episodes=1 policy=scalingup evaluation=table_top_bus_balance

The error is as follows:

openai.error.InvalidRequestError: You requested a length 0 completion, but you did not set the 'echo'
parameter. That means that we will return no data to you. (HINT: set 'echo' to true in order for the
API to echo back the prompt to you.)

Any insights on this will be greatly appreciated. Thanks!

I meet the same issue "openai.error.InvalidRequestError: You requested a length 0 completion, but you did not set the 'echo' parameter."

I solve it by setting 'api_config.echo=True' at line 395 in openai_api.py.

I'll push an update soon to fix it! Thanks for pointing it out.
