DecodeCsv

public final class DecodeCsv

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.

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).
