TypeError: 'type' object is not subscriptable

Hi there! I am trying to run the Image Classification Experiments but got the following errors:

$ python run_experiment.py --config=configs/imagenet_nf_resnet_50_eps8.py --jaxline_mode=train_eval_multithreaded
Traceback (most recent call last):

TypeError: 'type' object is not subscriptable

I am unsure what is causing this issue and would appreciate any assistance in resolving it. Can you please advise on what steps I can take to fix this error and successfully run the experiments?

Thank you for your help!

Hi, based on these logs, it seems that the error is raised within the dp_accounting library, when tuple is used as a type annotation, because this syntax is not supported on python 3.8. Using a newer version of python (>=3.9) should make the error disappear.
