What version of h5py are you using ? (like what does python -c 'import h5py; print(h5py.__version__)' display ?

According to the h5py documentation this method was added in v3.0 : https://docs.h5py.org/en/latest/high/dataset.html?highlight=asstr#h5py.Dataset.asstr . I'm wondering if you have an older version installed which is causing this issue.

The version is 2.10.0 Then I updated the version to 3.6.0, the problem was solved.

Thank you very much!
