tensorflow:: ops:: DecodeCSV
#include <parsing_ops.h>
Convert CSV records to tensors.
Summary
Each column maps to one tensor.
RFC 4180 format is expected for the CSV records. (https://tools.ietf.org/html/rfc4180) Note that we allow leading and trailing spaces with int or float field.
Args:
- scope: A Scope object
- records: Each string is a record/row in the csv and all records should have the same format.
- record_defaults: One tensor per column of the input record, with either a scalar default value for that column or an empty vector if the column is required.
Optional attributes (see Attrs
):
- field_delim: char delimiter to separate fields in a record.
- use_quote_delim: If false, treats double quotation marks as regular characters inside of the string fields (ignoring RFC 4180, Section 2, Bullet 5).
- na_value: Additional string to recognize as NA/NaN.
Returns:
OutputList
: Each tensor will have the same shape as records.
