learner.step() error in tutorial.ipynb

[kruthof]

Hi! Running the tutorial I managed to construct the dataset and the learner. However, when running learner.step() I'm getting

'TypeError: 'ParallelInterleaveDataset' object is not an iterator'

Despite that, a few function calls are outdated, e.g.

• d4pg.D4PGLearner: argument 'dataset' instead of new: 'dataset_iterator'

[kruthof]

it seems like initiating D4PGLearner with dataset_iterator = dataset.iter() could solve that problem. However, then I am getting an ArttributeError: 'dict' object has no attribute 'discount' when calling learner.step(). I am getting a similar error when using DDPLearner with argument dataset=dataset.

Hi kruthof,

Thanks for your question and apologies for the delay in getting back. Following the release of the new edition of Acme, along with new quickstart and tutorial guides, I'm going to mark this as closed.

Hope you like the new code and material! Happy Acming!
