Can't start an observer client with a PTZ camera to play around

[isaryo]

I tried to it.

Then I received the following error message.

Traceback (most recent call last):
  File "code/spectator.py", line 21, in <module>
    from utils import anchor_cameras
  File "/home/use/Multiverse/forking_paths_dataset/code/utils.py", line 77, in <module>
    sun_azimuth_angle=20.0)
Boost.Python.ArgumentError: Python argument types in

Do you have any solutions?

This may be because you have installed a different carla python environment. Try uninstalling carla and run again. This line in spectator.py imports the carla 0.9.6 library from the *.egg file in the repo.
