Detailed Description

Application-implemented logging interface for the builder, refitter and runtime.

The logger used to create an instance of IBuilder, IRuntime or IRefitter is used for all objects created through that interface. The logger should be valid until all objects created are released.

The Logger object implementation must be thread safe. All locking and synchronization is pushed to the interface implementation and TensorRT does not hold any synchronization primitives when calling the interface functions.

Member Enumeration Documentation

◆ Severity

enum class nvinfer1::ILogger::Severity : int32_t

strong

The severity corresponding to a log message.

Enumerator
kINTERNAL_ERROR	An internal error has occurred. Execution is unrecoverable.
kERROR	An application error has occurred.
kWARNING	An application error has been discovered, but TensorRT has recovered or fallen back to a default.
kINFO	Informational messages with instructional information.
kVERBOSE	Verbose messages with debugging information.

Member Function Documentation

◆ log()

virtual void nvinfer1::ILogger::log	(	Severity	severity,
		AsciiChar const *	msg
	)

pure virtualnoexcept

A callback implemented by the application to handle logging messages;

Parameters

severity	The severity of the message.
msg	A null-terminated log message.

Usage considerations

Allowed context for the API call
- Thread-safe: Yes, this method is required to be thread-safe and may be called from multiple threads when multiple execution contexts are used during runtime, or if the same logger is used for multiple runtimes, builders, or refitters.
