code in your document about making datasets can not be reproduced

I am reproducing your code about to make datasets. It needs to import "make_classification_dataset" as shown in your documents:
I copy it and paste it in my jupyter notebook directly, and install avalanche-lib 5.0 correctly. However, it reports an error that "cannot import name 'make_classification_dataset' from 'avalanche.benchmarks.utils'"：

How can I correct this error? Thank you very much.
