尝试为 GRPC 请求创建 ManagedChannel 时，类 io.grpc.Channel 的加载器约束违规

问题描述 投票：0回答：1

我正在尝试设置 grpc 客户端，以便为我的项目在 Kotlin 中向 Nvidia Triton 推理服务器（版本：23.06-py3）发出推理请求。

我已经使用 gradle 设置了协议代码生成（下面附有 build.gradle.kts），但是当我尝试创建 ManagedChannel 来传递给 InferenceService 协程时，我收到此运行时错误

val channel = ManagedChannelBuilder.forTarget("127.0.0.1:8001")
            .usePlainText()
            .build()
val inferenceStub = GRPCInferenceServiceGrpcKt.GRPCInferenceServiceCoroutineStub(channel)
val modelLive = inferenceStub.modelReady(
    GrpcService.ModelReadyRequest.newBuilder()
         .setName("santacoder_huggingface")
         .build()
)

我认为这可能是由 gradle 文件中的 grpc-netty-shaded 依赖项引起的，但我不确定，因为我对此很陌生。我尝试删除 grpc-netty-shaded 以支持 grpc-netty，并且还尝试删除依赖项，但这两者都会导致此错误
