This error is usually caused by a NumPy version mismatch after installing new dependencies in the notebook environment.

Even though the code is correct, the runtime may still be using an older compiled NumPy backend, which leads to:

ImportError: cannot import name '_center'

Fix:

Restart the runtime (Runtime → Restart runtime), then run all cells again.

This worked for me when running the demo.

Alternatively, you can ensure a stable setup by reinstalling NumPy:

pip install --upgrade numpy

You may also need to restart the runtime after upgrading NumPy for the changes to take effect.

This typically happens in Colab because packages are installed mid-session, and the runtime does not reload compiled dependencies automatically.
