Using callback for GAIL [question]

See original GitHub issue

I am trying to save the GAIL model during training. I’m using the example code from the Callback documentation as reference:


from stable_baselines import GAIL
from stable_baselines.gail import ExpertDataset, generate_expert_traj
from stable_baselines.common.callbacks import CheckpointCallback

checkpoint_callback = CheckpointCallback(save_freq=1000, save_path='./logs/', name_prefix='gail')
dataset = ExpertDataset(expert_path='C:/IL_UAV/GAIL-TF-SB/stable_baselines/gail/dataset/expert_pendulum.npz', traj_limitation=10, verbose=1)

model = GAIL('MlpPolicy', 'Pendulum-v0', dataset, verbose=1)
model.learn(2000, callback=checkpoint_callback)

I get the following **AttributeError:** 'NoneType' object has no attribute 'process'. What should I be doing?

PS: I am relatively new to both Stable Baselines and RL!

Hey @haochihlin!

You’re right, sincere apologies (just edited my earlier reply.) I checked things in a hurry, and wrote just main in place of __main__ so the code never really ran, and hence showed no errors. There are a quite a few mistakes and inefficiencies in this whole thread.

@araffin, it would be great if you could delete this issue. I will open a new issue with a clear description of the error. Sorry for the trouble!

Hi. The issue is still unresolved. Closed this by mistake! (opened another better-worded issue)
