TypeError, 'Regexp cannot be negated' in ReDo when running sac_train_eval.py

[seekingpure]

I tried to run sac_train_eval.py with sac_mujoco_dense_config.gin, and I used the following command:
python -um dopamine.labs.redo.train --base_dir /tmp/dopamine_runs --gin_files dopamine/labs/redo/tfagents/configs/sac_mujoco_dense_config.gin

I tried to run this both in linux and windows operating system, and I met the same error as follows:
Traceback (most recent call last):
File "D:/experiments/2023.12.11 dopamine/dopamine-master/dopamine/labs/redo/tfagents/sac_train_eval.py", line 26, in
import reverb
File "D:\Anaconda3\envs\mujocotaac\lib\site-packages\reverb.py", line 64
raise TypeError, 'Regexp cannot be negated'
^
SyntaxError: invalid syntax
I guess this is related to the version of the revert package, so I tried to change the version. But it did not work.
I wonder if there is another way to slove this problem. Looking forward to your reply. Thanks.

It seems like the issue you're encountering is related to a Python 2 syntax incompatibility. Use ''python3'' in the Command Line

Maybe you install with a wrong package named reverb, and you should install dm-reverb.
