Class DecodeCSV

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.DecodeCSV

All Implemented Interfaces:

Iterable<Operand<Object>>, Op

@Operator
public final class DecodeCSV
extends PrimitiveOp
implements Iterable<Operand<Object>>

Convert CSV records to tensors. 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.

Method Detail

create

public static DecodeCSV create(Scope scope,
                               Operand<String> records,
                               Iterable<Operand<?>> recordDefaults,
                               DecodeCSV.Options... options)

Factory method to create a class to wrap a new DecodeCSV operation to the graph.

Parameters:

scope - current graph scope

records - Each string is a record/row in the csv and all records should have the same format.

recordDefaults - 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.

options - carries optional attributes values

Returns:

a new instance of DecodeCSV

fieldDelim

public static DecodeCSV.Options fieldDelim(String fieldDelim)

Parameters:

fieldDelim - char delimiter to separate fields in a record.

useQuoteDelim

public static DecodeCSV.Options useQuoteDelim(Boolean useQuoteDelim)

Parameters:

useQuoteDelim - If false, treats double quotation marks as regular characters inside of the string fields (ignoring RFC 4180, Section 2, Bullet 5).

naValue

public static DecodeCSV.Options naValue(String naValue)

Parameters:

naValue - Additional string to recognize as NA/NaN.

selectCols

public static DecodeCSV.Options selectCols(List<Long> selectCols)

Parameters:

selectCols -

output

public List<Output<?>> output()

Each tensor will have the same shape as records.

iterator

public Iterator<Operand<Object>> iterator()

Specified by:

iterator in interface Iterable<Operand<Object>>
