Do you know how to debug this error?
Every time you open a notebook, you have to run all of the cells starting from the top. That is how the environment is created and the assets are loaded.

me to but name error: name ‘x_train’ is not defined?
Did you run all of the cells after opening the notebook?
Because x_train is defined by running the cell in section “3 - Dataset”
Please post a screen capture image that shows the entire error message - but do not include your code.
