getDimsCHWFromDims(dimsCHW, dims)

Sets values on a NvDsInferDimsCHW structure from a NvDsInferDims structure.

Typedefs

typedef NvDsInferObjectDetectionInfo NvDsInferParseObjectInfo

A typedef defined to maintain backward compatibility.

Enums

enum NvDsInferDataType

Specifies the data type of a layer.

Values:

enumerator FLOAT

Specifies FP32 format.

enumerator HALF

Specifies FP16 format.

enumerator INT8

Specifies INT8 format.

enumerator INT32

Specifies INT32 format.

enum NvDsInferStatus

Enum for the status codes returned by NvDsInferContext.

Values:

enumerator NVDSINFER_SUCCESS

NvDsInferContext operation succeeded.

enumerator NVDSINFER_CONFIG_FAILED

Failed to configure the NvDsInferContext instance possibly due to an erroneous initialization property.

enumerator NVDSINFER_CUSTOM_LIB_FAILED

Custom Library interface implementation failed.

enumerator NVDSINFER_INVALID_PARAMS

Invalid parameters were supplied.

enumerator NVDSINFER_OUTPUT_PARSING_FAILED

Output parsing failed.

enumerator NVDSINFER_CUDA_ERROR

CUDA error was encountered.

enumerator NVDSINFER_TENSORRT_ERROR

enumerator NVDSINFER_LOG_INFO
enumerator NVDSINFER_LOG_DEBUG

Functions

const char *NvDsInferStatus2Str(NvDsInferStatus status)

Get the string name for the status.

Return

String name for the status. Memory is owned by the function. Callers should not free the pointer.
