Problem description
I am trying to run the TestModel and I have found a TypeError when connecting to AirSim. It seems to me that it could come from the Tornado version, but actually I have tried with more than one version and the problem continues.
Problem details
Details of the problem are as follow:
When I run the script .\AD_Cookbook_Start_Airsim.ps1 landscape, everything runs perfectly in UE4 and AirSim but once I run the Jupyter Notebook (Step 2: "Test the model") as follows, it is when I find the error after the second cell (posted below):
model = load_model(MODEL_PATH)
client = CarClient()
client.confirmConnection()
client.enableApiControl(True)
car_controls = CarControls()
print('Connection established!')
Then I found the folowing error message:
TypeError Traceback (most recent call last)
in
1 model = load_model(MODEL_PATH)
2
----> 3 client = CarClient()
4 client.confirmConnection()
5 client.enableApiControl(True)

Thanks a lot in advance.
@gonzaloaguilarjimenez may I ask how did you solve this issue?
@gonzaloaguilarjimenez would you mind sharing how you solved it?
Thanks!
downgrading torando worked for me. conda install tornado=4.5.3
jupyter/notebook#3407 (comment)
Thanks anyways
Hello,
It was a problem with the anaconda version apparently.
I just uninstalled and reinstalled Anaconda and then it worked.
I do not remember the previous version, but if necessary I can check the current one.
Best regards.
I'm getting the same error. What version of anaconda ended up working?
