executor_train: train_qwen3_4b_adpo.sh fails with Could not find 'data/legacy_data'

[benj617]

Hi, thanks for open-sourcing Agent0.

I followed the README and completed the previous steps, but when I run:

bash examples/train/math_tir/train_qwen3_4b_adpo.sh

it fails with:

In 'ppo_trainer': Could not find 'data/legacy_data'

It looks like executor_train/verl_tool/trainer/config/ppo_trainer.yaml references data@data: legacy_data, but the corresponding config/data/legacy_data.yaml file is missing.

Could you please clarify:

1. Is the executor_train directory complete in the current public release?
2. Is there any missing config or preprocessing file for executor training?
3. Could you provide more detailed instructions for executor data preparation and the exact training script/config expected for the Qwen3-4B ADPO setup?

I would also appreciate a clearer description of how the data produced in the data curation step should be converted or placed for executor_train.

Thanks.
