class LiteBackend(value)

The backend type enum, default only

LITE_DEFAULT = 0

class LiteDeviceType(value)

The backend device type enum

Note

compute and storage will base on the device

LITE_ATLAS = 3

LITE_CAMBRICON = 5

LITE_CPU = 0

LITE_CUDA = 1

LITE_DEVICE_DEFAULT = 7

LITE_NPU = 4

class LiteDataType(value)

The tensor data type enum

Note

half for float16, int for int32

LITE_FLOAT = 0

LITE_HALF = 1

LITE_INT = 2

LITE_INT16 = 3

LITE_INT8 = 4

LITE_UINT16 = 6

LITE_UINT8 = 5

class LiteTensorPhase(value)

The tensor type enum .. note:: LITE_IO for both LITE_INPUT and LITE_OUTPUT

LITE_INPUT = 1

LITE_IO = 0

LITE_OUTPUT = 2

class LiteIOType(value)

The input and output type enum, include SHAPE and VALUE sometimes user only need the shape of the output tensor

LITE_IO_SHAPE = 1

LITE_IO_VALUE = 0

class LiteAlgoSelectStrategy(value)

Operation algorithm seletion strategy type enum, some operations have multi algorithms, different algorithm has different attribute, according to the strategy, the best algorithm will be selected.

Note

These strategies can be combined LITE_ALGO_HEURISTIC | LITE_ALGO_PROFILE means: if profile cache not valid, use heuristic instead

LITE_ALGO_HEURISTIC | LITE_ALGO_REPRODUCIBLE means: heuristic choice the reproducible algo

LITE_ALGO_PROFILE | LITE_ALGO_REPRODUCIBLE means: profile the best algorithm from the reproducible algorithms set

LITE_ALGO_PROFILE | LITE_ALGO_OPTIMIZED means: profile the best algorithm form the optimzed algorithms, thus profile will process fast

LITE_ALGO_PROFILE | LITE_ALGO_OPTIMIZED | LITE_ALGO_REPRODUCIBLE means: profile the best algorithm form the optimzed and reproducible algorithms

LITE_ALGO_HEURISTIC = 1

LITE_ALGO_OPTIMIZED = 8

LITE_ALGO_PROFILE = 2

LITE_ALGO_REPRODUCIBLE = 4

class LiteLogLevel(value)

Log level enum

Note

DEBUG: The most verbose level, printing debugging info

INFO: The default level

WARN: Printing warnings

ERROR: The least verbose level, printing errors only

DEBUG = 0

ERROR = 3

INFO = 1

WARN = 2
