Confusing warnings when run_6_fineResamp and run_7_grid_baseline

[wandi12345]

Hello evereyone,

I'm using stackStripMap.py to process TerraSAR data, and when I run run_6_fineResamp and run_7_grid_baseline, some warnings appear, and I don't understand the meaning of these warnings, which makes me confused. Is this just a warning that can be ignored, or is there some error that needs to be corrected?
