Construct a Stream from a MOA stream object.
Usually, you will want to construct a Stream using the
capymoa.stream.stream_from_file()
function.- Parameters:
moa_stream – The MOA stream object to read instances from. Is None if the stream is created from a numpy array.
schema – The schema of the stream. If None, the schema is inferred from the moa_stream.
CLI – Additional command line arguments to pass to the MOA stream.
- Raises:
ValueError – If no schema is provided and no moa_stream is provided.
ValueError – If command line arguments are provided without a moa_stream.
- __iter__() Iterator[_AnyInstance] [source]#
Get an iterator over the stream.
This will NOT restart the stream if it has already been iterated over. Please use the
restart()
method to restart the stream.- Yield:
An iterator over the stream.
- __next__() _AnyInstance [source]#
Get the next instance in the stream.
- Returns:
The next instance in the stream.
- download(working_directory: Path) Path [source]#
Download the dataset and return the path to the downloaded dataset within the working directory.
- Parameters:
working_directory – The directory to download the dataset to.
- Returns:
The path to the downloaded dataset within the working directory.
- extract(stream_archive: Path) Path [source]#
Extract the dataset from the archive and return the path to the extracted dataset.
- Parameters:
stream_archive – The path to the archive containing the dataset.
- Returns:
The path to the extracted dataset.
