Missing geojson for Tuto 3

[eroan-marie]

When I tried to run the tutorial 3 cloud classification, I get an error about a missing file at this line :

with open("cloud_class.geojson") as f:
    gj_data = geojson.load(f)

Error:

FileNotFoundError                         Traceback (most recent call last)
Cell In[17], line 1----> 1 with open("cloud_class.geojson") as f:      2     gj_data = geojson.load(f)

I didn't find this file in the project.
Is this a file that I need to pull from somewhere else or is it just missing ?
