What about the tutorials in jupyter notebook format? Do we have a similar problem there or is it only concerning the .py scripts? |

👍 It is only concerning the scripts and not the notebooks. |

The tutorials are now encapsulated in methods and it is checked that the code is executed only by the main process but none of the subprocesses when using multiprocessing. This change only affects Windows users.
On Windows, this check is necessary to prevent the tutorial code from being executed in every subprocess when using multiprocessing. Without the check, every subprocess tries to spawn a new elasticsearch instance, write to the same log file, etc., which leads to "Permission denied" errors or "failed to obtain node locks" exceptions as reported in the following issue
