Cannot import opendp.smartnoise.core using Azure ML Notebooks , OSError: ... cannot open shared object file: No such file or directory

Question

I have a Mac with M1. When I try to follow the instructions of the notebook exercise "Explore Differential Privacy" and execute the command

import opendp.smartnoise.core as sn

I get the following error:

--------------------------------------------------------------------------

OSError: /anaconda/envs/azureml_py38/lib/python3.8/site-packages/opendp/smartnoise/core/lib/libsmartnoise_ffi.so: cannot open shared object file: No such file or directory

although installing opendp-smartnoise worked fine:

pip install opendp-smartnoise==0.1.4.2

Requirement already satisfied: charset-normalizer<4,>=2 in /anaconda/envs/azureml_py38/lib/python3.8/site-packages

What is wrong and what can I do? (Restarting the kernel did not work)

Thanks!
