mlx.data.stream_csv_reader

mlx.data.stream_csv_reader(file: object, sep: str = ', ', quote: str = '"', *, local_prefix: str = '', file_fetcher: mlx::data::core::FileFetcher = None, file_fetcher_handle: mlx::data::core::FileFetcherHandle = None) → mlx.data._c.Stream

Stream samples from a csv file.

The file can be given as a filename or any python object that has a read() and a seek() method. Optionally a file fetcher can be passed to fetch the file from a remote location.

In the case that a file object was created from a file fetched by an MLX file fetcher, then a handle can be passed (the return value of fetch) to ensure that the file is kept on disk for the lifetime of the stream.

Parameters:

• file (str or python readable object) – The file to read the csv from.

• sep (str) – The field separator in the csv file. (default: ‘,’)

• quote (str) – The quotation character in the csv file. (default: ‘”’)

• local_prefix (str) – The filepath prefix to use to read the files. (default: ‘’)

• file_fetcher (mlx.data.core.FileFetcher, optional) – A file fetcher to read the csv files possibly from a remote location.

• file_fetcher_handle (mlx.data.core.FileFetcherHandle, optional) – A handle to ensure that the file is kept on disk if a stream is passed instead of a filename.
