public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "DecodeCSV"

Public Methods

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

Factory method to create a class wrapping a new DecodeCsv operation.

Parameters
scope current 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

public static DecodeCsv.Options fieldDelim (String fieldDelim)

Parameters
fieldDelim char delimiter to separate fields in a record.

public Iterator< Operand < TType >> iterator ()

public static DecodeCsv.Options naValue (String naValue)

Parameters
naValue Additional string to recognize as NA/NaN.

public List< Output <?>> output ()

Each tensor will have the same shape as records.

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

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).
