Thanks, now the cell is working. There were a few other lines missing in Step 3: EO data extractions — I had to add !pip install geopandas and import geopandas as gpd. Also, the line that saves the samples_df to file was commented out (# samples_df.to_file(samples_df_path, driver='GPKG')), so I uncommented it. After that, everything worked fine. Thank you!
