Fail to collect data about behaviorretrieval

[MaxDu17]

Hi! Thanks for reaching out--this is interesting. Just to confirm, you were running something along the lines of

python run_trained_agent.py \
  --agent SquarePeg \
  --eval_path datasets/square_machine_policy/ \
  --reference_data datasets/square/ph/image.hdf5 \
  --config configs/image_collection.json \
  --machine_oracle --success_only --dataset_obs \
  --dataset_path datasets/square_machine_policy/square_10_good.hdf5 \
  --n_rollouts 10 --horizon 400 --seed 11

The run_trained_agent needs a checkpoint if --machine_oracle is not passed in. Otherwise, it should default to the machine policy (if this is not the case, please let me know--that would definitely be a mistake on my end)

@davidkillerhahaha Hi,Have you solved the problem? I need your help. Thanks.

Hi! Can you give more details about your particular setup? This might be a problem on my end, but it should have a very easy fix

@MaxDu17 Hi!MAX,When I run run_trained_agent.py,error appear：

What makes this error?
Hope some tips,thanks.

Have you tried creating the datasets/square_machine_policy folder before running the script? It might be having some difficulty with recursive file creation

[ZlSong417]

Thanks for your advice, I have successfully created datasets/square_machine_policy.
