java - Nvidia Triton tensorflow 字符串参数

Question

我有一个带有字符串参数作为输入的张量流模型。Triton Java api 中的字符串使用什么类型？

例如。模型定义

    {
        "name":"test_model", "platform":"tensorflow_savedmodel", "backend":"tensorflow",
            "version_policy":{
        "latest":{
            "num_versions":1
        }
    },
        "max_batch_size":8,
            "input":[{
        "name":"input_text", "data_type":"TYPE_STRING", "format":"FORMAT_NONE", "dims":[1],"reshape":{
            "shape":[]},"is_shape_tensor":false, "allow_ragged_batch":false
    }]

客户端代码

String text = "the text";

    InferTensorContents.Builder input0_data = InferTensorContents.newBuilder();
    input0_data ... how to set

Answer 1

Triton 使用 google protobufs，所以这是他们使用 ByteString 的方式

    String text = "textstring";
    InferTensorContents.Builder input0input_text = InferTensorContents.newBuilder();
    final ByteString input = ByteString.copyFrom(text, Charset.forName("UTF8"));
    System.out.println(input.size());
    input0input_text.addByteContents(input);
