Problem description

The output seems good, but it cannot generate the corresponding image，llm.png and astar.png are white image output is here： {'start': [5, 5], 'goal': [45, 25], 'size': [51, 31], 'horizontal_barriers': [[10, 0, 25], [15, 30, 50]], 'vertical_barriers': [[25, 10, 22]], 'range_x': [0, 51], 'range_y': [0, 31]} {'operation': 462, 'storage': 470, 'length': 49.4558441227157} {'start': [5, 5], 'goal': [45, 25], 'size': [51, 31], 'horizontal_barriers': [[10, 0, 25], [15, 30, 50]], 'vertical_barriers': [[25, 10, 22]], 'range_x': [0, 50], 'range_y': [0, 30]} [(5, 5), (26, 9), (25, 23), (45, 25)] (5, 5) (26, 9) (26, 9) (25, 23) (25, 23) (45, 25) {'operation': 103, 'storage': 232, 'length': 49.45584412271569, 'llm_output': [(5, 5), (26, 9), (25, 23), (45, 25)]}
