Hi! I run the tutourial example 1 codes in Jupyter notebook. It showed me the source station map, and the following errors: <img width="1740" height="494" alt="Image" src="https://github.com/user-attachments/assets/0c97c7a4-9d32-4219-b4c1-429168339f9f" /> I can not get the crossSection plot. Could any body help me deal with this issue?
