Protobuf version mismatch

[durson]

Hi, I cannot build lingvo. My setup: tf-1.14 (using protobuf 3.7.1) Command: bazel build --verbose_failures //lingvo/core/ops:py_x_ops Error: bazel-out/k8-fastbuild/genfiles/lingvo/core/ops/hyps.pb.h:12:2: error: #error This file was generated by a newer version of protoc which is #error This file was generated by a newer version of protoc which is ^ bazel-out/k8-fastbuild/genfiles/lingvo/core/ops/hyps.pb.h:13:2: error: #error incompatible with your Protocol Buffer headers. Please update #error incompatible with your Protocol Buffer headers.

The protobuf version is set here. You can check the history of that file to see the sha256. If you use an older version, you are on your own in an unsupported path. Other things might break.
