Bug in logreplay

[ch3ny1]

When using the logreplay tool, the following bug was encountered

Traceback (most recent call last): File "scenarios_manager.py", line 75, in scenarion_manager.tick() File "scenarios_manager.py", line 63, in tick scene_manager.start_simulator() File "/media/chenyi/wiser/Research/OpenCOOD/logreplay/scenario/scene_manager.py", line 140, in start_simulator self.scene_name) File "/media/chenyi/wiser/Research/OpenCOOD/logreplay/map/map_manager.py", line 155, in init self.generate_lane_cross_info() File "/media/chenyi/wiser/Research/OpenCOOD/logreplay/map/map_manager.py", line 546, in generate_lane_cross_info tl_id = self.associate_lane_tl(mid_lane) File "/media/chenyi/wiser/Research/OpenCOOD/logreplay/map/map_manager.py", line 405, in associate_lane_tl trigger_path = Path(trigger_poly.boundary) File "/home/chenyi/miniconda3/envs/opencood/lib/python3.7/site-packages/matplotlib/path.py", line 128, in init vertices = _to_unmasked_float_array(vertices) File "/home/chenyi/miniconda3/envs/opencood/lib/python3.7/site-packages/matplotlib/cbook/init.py", line 1333, in _to_unmasked_float_array return np.asarray(x, float)

TypeError: float() argument must be a string or a number, not 'LineString'

Solved (not so elegantly) through adding a try-except handle in the corresponding file in the matplotlib by changing line 1333 from

return np.asarray(x, float)

to

try:
    return np.asarray(x, float)
except TypeError:
    return np.asarray(x.xy, float).transpose()

What is your shapely version? This is very likely caused by the version of shaplely

[ch3ny1]

It is shapely==2.0.0, as specified in environment.yml. numpy==1.12.6, matplotlib==3.4.2

Another simpler solution I used was changing line 405 in map_manager.py

from

trigger_path = Path(trigger_poly.boundary)

to

trigger_path = Path(np.array(trigger_poly.boundary.coords))

P.S. I have shapely==2.0.0 as specified in environment.yml too

What is the CARLA version you are using?

[ch3ny1]

It’s 0.9.12. And thanks for the solution! Will try it out later
