tf.io.decode_csv
Convert CSV records to tensors. Each column maps to one tensor.
tf.io.decode_csv(
records, record_defaults, field_delim=',', use_quote_delim=True,
na_value='', select_cols=None, name=None
)
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 |
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). |
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. |
name | A name for the operation (optional). |
Returns |
A list of Tensor objects. Has the same type as record_defaults . Each tensor will have the same shape as records. |
Raises |
ValueError | If any of the arguments is malformed. |
