[hunterkeith2017]

script: "nuplan_framework.ipynb" When I start to train the model in the jupyter notework，something about zmq gets wrong errors. Does anybody help me?

Hi @hunterkeith2017,

It seems that this happens before the training segment of the tutorial. Unfortunately, I am unable to recreate your error. Do you have your virtual environment setup correctly?

[IvanChen777]

Hi, @patk-motional , I also meet the same issue in v1.0. It seems that I cannot run the trainining code in jupyter notebook, but I can run the training code in terminal, I think the environment setting is fine. Otherwise, it will not work in terminal.

Have you tried specifying a different port for jupyter?

Have you tried specifying a different port for jupyter?

I don't know what is that mean for specifying a different port for jupyter, but after I use the v1.1 and apply the trainval data, it could run in the jupyter notebook
