Enum Constant Detail

FLOAT

public static final DataType FLOAT

32-bit single precision floating point.

DOUBLE

public static final DataType DOUBLE

64-bit double precision floating point.

INT32

public static final DataType INT32

32-bit signed integer.

UINT8

public static final DataType UINT8

8-bit unsigned integer.

STRING

public static final DataType STRING

A sequence of bytes.

TensorFlow uses the STRING type for an arbitrary sequence of bytes.

INT64

64-bit signed integer.

BOOL

public static final DataType BOOL

Boolean.

Method Detail

values

public static DataType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DataType c : DataType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DataType valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null

byteSize

public int byteSize()

Returns the size of an element of this type, in bytes, or -1 if element size is variable.

fromClass

public static DataType fromClass(Class<?> c)

Returns the DataType of a Tensor whose elements have the type specified by class c.

Parameters:

c - The class describing the TensorFlow type of interest.

Returns:

The DataType enum corresponding to c.

Throws:

IllegalArgumentException - if objects of c do not correspond to a TensorFlow datatype.
