Suppress TensorRT warning and logging messages in Terminal


I’m running TensorRT models to inference images captured from a camera. However, I’m seeing a ton of terminal output which I suspect is slowing down the inference framerate. Sample terminal output is shown below - can I disable all TensorRT terminal logging and how?


TensorRT Version: 8.4.1
GPU Type: Jetson Xavier NX 16GB production
CUDA Version: 11.4.14
CUDNN Version: 8.4.1
Operating System + Version: Jetson Linux 35.1
Python Version (if applicable): 3.8

Sample Output Log to Suppress:

[03/07/2023-15:30:23] [TRT] [I] The logger passed into createInferRuntime differs from one already provided for an existing builder, runtime, or refitter. Uses of the global logger, returned by nvinfer1::getLogger(), will return the existing value.

Hi @zhifeis ,
Can you please share the detailed logs with us?
For the TRT part code, youcan change the log level and can try setting the log level to kWARNING


The code responsible for the terminal output above is shown here:

def load_trt_model(model_path, device):
    Binding = namedtuple('Binding', ('name', 'dtype', 'shape', 'data', 'ptr'))
    logger = trt.Logger(trt.Logger.INFO)
    trt.init_libnvinfer_plugins(logger, namespace="")
    with open(model_path, 'rb') as f, trt.Runtime(logger) as runtime:
        model = runtime.deserialize_cuda_engine(
    bindings = OrderedDict()
    for index in range(model.num_bindings):
        name = model.get_binding_name(index)
        dtype = trt.nptype(model.get_binding_dtype(index))
        shape = tuple(model.get_binding_shape(index))
        data = torch.from_numpy(np.empty(shape, dtype=np.dtype(dtype))).to(device)
        bindings[name] = Binding(name, dtype, shape, data, int(data.data_ptr()))
    binding_addrs = OrderedDict((n, d.ptr) for n, d in bindings.items())
    context = model.create_execution_context()

    # warmup for 10 times
    for _ in range(10):
        tmp = torch.ones(1,3,288,640).half().to(device)
        binding_addrs['input.1'] = int(tmp.data_ptr())
    return [binding_addrs, context, bindings]

How would I set the log level? Where in the code would I do that?

Hi @zhifeis ,

Please refer to the below link for details on enabling the logger.


U r really lazy for the greenhands :) I have seen this answer many times from Google posted by u, still not knowing where to start @AakankshaS

  1. Do we need to modify a python file in the TensortRT python library? If so , could you tell us the name of the file or its typical system path?
  2. Or we can change the Log level of TRT in our python code? If so, is there an example?
