Encountered an TypeError when trying to run the data collection as well as the pretrained model

[AIasd]

Hello, I followed the instruction and was trying to run 1.data collection 2.the pre-trained model but encountered the same error message as the following. I would appreciate if you can shed some lights on the error message. Thanks!

seems like a py-trees dependency problem.

can you run

pip freeze | grep tree

and verify the version of py-trees you're using?
i'm using 0.8.3, as stated in

carla_project/requirements.txt

Yes, this solves my issue. Thank you so much!

Hi,
I have the same problem:

Preparing scenario: RouteScenario_0
The scenario cannot be loaded
Traceback (most recent call last):
File "scenario_runner.py", line 388, in _load_and_run_scenario

No more scenarios .... Exiting

and when I run pip freeze | grep tree
I get:
py-trees==0.8.3
rqt_tf_tree==0.6.2

And it is still not working, what can be the problem?

Hi @Yosefnoorani,
I am facing the same error. Did you find a fix for this?
