mlx.data.Stream.csv_reader_from_key#

Stream.csv_reader_from_key(self: mlx.data._c.Stream, key: str, sep: str = ', ', quote: str = '"', from_memory: bool = False, local_prefix: os.PathLike = '', file_fetcher: mlx::data::core::FileFetcher = None) → mlx.data._c.Stream#

Read the csv file pointed to from the array at key and yield the contents as separate samples in the stream.

This operation is similar to stream_csv_reader() but applied once for every sample in the stream and the samples from the resulting stream are returned until exhaustion.

Parameters:

  • key (str) – The sample key that contains the array we are operating on.

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

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

  • from_memory (bool) – Read the csv from the contents of the array rather than treating the array as a filename. (default: False)

  • 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.
