TypeError: unsupported operand type(s) for *: 'ZMQIOLoop' and 'float'

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)

@gonzaloaguilarjimenez would you mind sharing how you solved it? Thanks!

downgrading torando worked for me. conda install tornado=4.5.3 https://github.com/jupyter/notebook/issues/3407#issue-303235000

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?
