Description
This PR fixes an issue with the
Pipeline
s that have aGlobalStep
asPushToHub
at the end, and don't propagate theinputs
, so that the cache for the last step will contain an empty file, so that the_create_dataset
method will fail since there will be no data.Also
_create_dataset
docstring, andPipeline.run
and_get_filename
return type-hints have been fixed. Besides that the_TYPE_MAP
mapping to Parquet types has been updated to includetype(None): pa.null()
(this could also be handled in a better way, but not sure).
