Does anyone know what happened? What can I do to fix this issue? Thanks a lot!
NumPy 1.20 is deprecating part of their API. You have three options:
- Wait for the next Qiskit release (0.24). It should be around the corner (the PR fixing this was merged already).
- Downgrade NumPy running
!pip install numpy==0.19in the notebook and restart it.
- Ignore warnings:
import warnings warnings.filterwarnings('ignore')
