Triton Information
nvcr.io/nvidia/tritonserver:25.02-py3

To Reproduce
Start server:
docker run --gpus all --rm -p 8000:8000 -p 8001:8001 -p 8002:8002 -v ${PWD}/model_repository:/models nvcr.io/nvidia/tritonserver:25.02-py3 tritonserver --model-repository=/models --model-control-mode=explicit

Client code:

class Power:
    def __init__(self, triton: RemoteTriton):
        triton.bind(
            model_name="Power",
            infer_func=self.__cal__,
            inputs=[
                Tensor(dtype=np.float32, shape=(-1,)),
                Tensor(dtype=np.float32, shape=(-1,)),
            ],
            outputs=[
                Tensor(name="power", dtype=np.float32, shape=(-1,)),
            ],
            config=ModelConfig(max_batch_size=128),
        )

    @batch
    def __cal__(self, **inputs):
        a_batch, b_batch = inputs.values()
        dot_result = np.power(a_batch, b_batch)
        return {"power": dot_result}
    with RemoteTriton(url="grpc://localhost:8001") as triton:

        power = Power(triton=triton)

        logger.info("Starting triton server...")
        triton.serve()

Expected behavior
Model loaded to server
