TFオブジェクト検出API検出モデルの再トレーニング：「object_detection.protos.SsdFeatureExtractor」には「batch_norm_trainable」という名前のフィールドがありません

Question

Tensorflow Object DetectionAPIを使用してmobilenetv2 SSDを再トレーニングしていますが、Windows環境とUbuntu環境の両方でこの特定のエラーが発生します。
以下の私の環境は、python 3.5、cuda 9.0、およびtensorflow-gpu1.6のWindows10です。protobuf3.4.0でprotobufをコンパイルしました。
インストールテスト を実行しましたが、問題はなかったので、自分のデータセットを試してみて、google.protobuf.text_format.ParseError: 108:7 : Message type "object_detection.protos.SsdFeatureExtractor" has no field named "batch_norm_trainable".エラーが発生しました。

私が試したこと：

• Tf1.5を使用-1.7
• Mobilenet v1SSDのトレーニング

エラーコード全体：

この構成ファイル の修正バージョンを使用してmobilenet v1 SSDでトレーニングを試みると、別のエラーが発生します。

私は先月ubuntuでmobilenetv1ssdモデルのトレーニングに成功しましたが、今日リポジトリを最初からインストールした後、このエラーが発生し始めました。
助けていただければ幸いです。ありがとうございました！

Ssd mobilenet v2の場合、このフィールドは非推奨になったため、「batch_norm_trainable：true」を削除できます。
