Can't import aesara on windows : FileNotFoundError

When I try to import aesara, the following error is raised. I'm working on Windows 10, 64bits.
Most surprisingly, the error occur in a jupyter-notebook but not in VS Code.

Please provide a minimal, self-contained, and reproducible example.

import aesara

Please provide the full traceback of any errors.
