Convert CSV records to tensors. Each column maps to one tensor.

RFC 4180 format is expected for the CSV records. ( Note that we allow leading and trailing spaces with int or float field.

records A Tensor of type string. Each string is a record/row in the csv and all records should have the same format.
record_defaults A list of Tensor objects with specific types. Acceptable types are float32, float64, int32, int64, string. 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.
field_delim An optional string. Defaults to ",". char delimiter to separate fields in a record.
use_quote_delim An optional bool. Defaults to True. If false, treats double quotation marks as regular characters inside of the string fields (ignoring RFC 4180, Section 2, Bullet 5).
name A name for the operation (optional).
na_value Additional string to recognize as NA/NaN.
select_cols Optional sorted list of column indices to select. If specified, only this subset of columns will be parsed and returned.

A list of Tensor objects. Has the same type as record_defaults. Each tensor will have the same shape as records.

ValueError If any of the arguments is malformed.
