… module (pythonGH-155318) The __main__ module executed as a script or a command has __spec__ set to None, so warn_explicit(module_globals=globals()) emitted a spurious DeprecationWarning. It also raised ImportError when the loader was unable to provide the source of the module: when the module was executed with -m (the loader can only handle its own module name) or as a command (the built-in importer has no source).

The main module executed as a script or a command has spec set to
None, so warn_explicit(module_globals=globals()) emitted a spurious
DeprecationWarning. It also raised ImportError when the loader was unable
to provide the source of the module: when the module was executed with -m
(the loader can only handle its own module name) or as a command (the
built-in importer has no source).
