can't print chinese in Python backend

[pogevip]

Python backend

import json
import triton_python_backend_utils as pb_utils


class TritonPythonModel:
    def initialize(self, args):
        self.model_config = model_config = json.loads(args['model_config'])
        output0_config = pb_utils.get_output_config_by_name(
            model_config, "OUTPUT0")

        output1_config = pb_utils.get_output_config_by_name(
            model_config, "OUTPUT1")

        # Convert Triton types to numpy types
        self.output0_dtype = pb_utils.triton_string_to_numpy(
            output0_config['data_type'])
        self.output1_dtype = pb_utils.triton_string_to_numpy(
            output1_config['data_type'])

    def execute(self, requests):
        output0_dtype = self.output0_dtype
        output1_dtype = self.output1_dtype

        responses = []
        for request in requests:
            print('你好')
            in_0 = pb_utils.get_input_tensor_by_name(request, "INPUT0")
            in_1 = pb_utils.get_input_tensor_by_name(request, "INPUT1")

            out_0, out_1 = (in_0.as_numpy() + in_1.as_numpy(), in_0.as_numpy() - in_1.as_numpy())

            # Create output tensors. You need pb_utils.Tensor
            # objects to create pb_utils.InferenceResponse.
            out_tensor_0 = pb_utils.Tensor("OUTPUT0",out_0.astype(output0_dtype))
            out_tensor_1 = pb_utils.Tensor("OUTPUT1",out_1.astype(output1_dtype))

            inference_response = pb_utils.InferenceResponse(
                output_tensors=[out_tensor_0, out_tensor_1])
            responses.append(inference_response)

        # You should return a list of pb_utils.InferenceResponse. Length
        # of this list must match the length of `requests` list.
        return responses

    def finalize(self):
        print('Cleaning up...')

output is binary. how to print chinese?

add export PYTHONIOENCODING=UTF-8 when start tritonserver @pogevip

docker run  --rm \
-p8000:8000 -p8001:8001 -p8002:8002 \
-v ${model_repo}:/models \
${image_name} \
bash -c "export PYTHONIOENCODING=UTF-8 && tritonserver --model-repository=/models "

ps, you may need to add flush=True when print, print('你好', flush=True)

Thanks @Jackiexiao for providing the solution. @pogevip I'm going to close this issue for now. Please re-open the issue if you would like to follow up with this.
