I did a docker install according to https://github.com/ageron/handson-ml3/tree/main/docker
When opening the Jupyter notebook at http://127.0.0.1:8888/lab/tree/02_end_to_end_machine_learning_project.ipynb and successvely run the cells by hitting [Shift]+[Enter], I get an error dialog saying

File Save Error for 02_end_to_end_machine_learning_project.ipynb
Permission denied: 02_end_to_end_machine_learning_project.ipynb

when running cell [4]:

from pathlib import Path
import pandas as pd
import tarfile
import urllib.request

def load_housing_data():
    tarball_path = Path("datasets/housing.tgz")
    if not tarball_path.is_file():
        Path("datasets").mkdir(parents=True, exist_ok=True)
        url = "https://github.com/ageron/data/raw/main/housing.tgz"
        urllib.request.urlretrieve(url, tarball_path)
    with tarfile.open(tarball_path) as housing_tarball:
            housing_tarball.extractall(path="datasets")
    return pd.read_csv(Path("datasets/housing/housing.csv"))

housing = load_housing_data()

Enter what you expected to happen

The code should run without error, and the targe directory for the download should be created.

If you found a workaround, describe it here

Thanks for your feedback. I suppose you are running this notebook locally? Did you start Jupyter notebook in the same directory as the notebook? If not, it might trying to create a directory in a location where your user account does not have the appropriate rights. Can you check whether your user has the rights to create the datasets directory?
