Question

我正在尝试使用以下代码从.proto文件动态生成protobuf消息：

MyMultiFileErrorCollector error_collector;
google::protobuf::compiler::DiskSourceTree source_tree;
source_tree.MapPath("", "../protofiles/");

data_proto_.importer = new (std::nothrow) 
google::protobuf::compiler::Importer(&source_tree,

&error_collector);
if (data_proto_.importer == nullptr) {
  LOG(ERROR) << "Create data proto import failed";
  return false;
}
data_proto_.file_dscrptr = data_proto_.importer->Import(
                           "thirdparty/tensorflow_serving- 
                           1.5.0/tensorflow_serving/apis/model.proto");
if (data_proto_.file_dscrptr == nullptr) {
  LOG(ERROR) << "Import proto["
             << data_proto_.proto_root
             << "][" << data_proto_.proto_path << "] failed";
  return false;
}

原始文件的定义如下：

syntax = "proto3";

package tensorflow.serving;
// option cc_enable_arenas = true;

import "google/protobuf/wrappers.proto";

// Metadata for an inference request such as the model name and version.
message ModelSpec {
  // Required servable name.
  string name = 1;

  // Optional version. If unspecified, will use the latest (numerical) version.
  // Typically not needed unless coordinating across multiple models that were co-trained and/or have inter-dependencies on the versions used at inference time.
  google.protobuf.Int64Value version = 2;

  // A named signature to evaluate. If unspecified, the default signature will
  // be used.
  string signature_name = 3;
}

错误如下：

E1210 13:23:00.616284 187180 
test/beijing/module/datahub/datahub_regression/down_stream.cc:126] 
Import[thirdparty/tensorflow_serving1.5.0/tensorflow_serving/
apis/model.proto] 
line[3] column[7] error: Option "cc_enable_arenas" unknown.

如果我从原始文件中删除此句子“ option cc_enable_arenas = true”，那没关系。我想进口商不支持选项，但是我不知道如何解决这个问题。

从.proto文件动态生成protobuf消息，该消息包含消息定义之外的“选项”字段
