CSVReader NewDyn(object filenames, ImplicitContainer<T> column_names, object column_dtypes, object skip_header_lines, ImplicitContainer<T> read_num_records_hint)
CSV-parsing reader for a `TimeSeriesInputFn`.
Parameters
-
objectfilenames - A filename or list of filenames to read the time series from. Each line must have columns corresponding to `column_names`.
-
ImplicitContainer<T>column_names - A list indicating names for each feature. `TrainEvalFeatures.TIMES` and `TrainEvalFeatures.VALUES` are required; `VALUES` may be repeated to indicate a multivariate series.
-
objectcolumn_dtypes - If provided, must be a list with the same length as
`column_names`, indicating dtypes for each column. Defaults to
tf.int64for `TrainEvalFeatures.TIMES` andtf.float32for everything else. -
objectskip_header_lines - Passed on to `tf.compat.v1.TextLineReader`; skips this number of lines at the beginning of each file.
-
ImplicitContainer<T>read_num_records_hint - When not reading a full dataset, indicates the number of records to parse/transfer in a single chunk (for efficiency). The actual number transferred at one time may be more or less.
