Question

前提・実現したいこと

現在、googlespeech-to-textを用いて音声ファイルをテキスト化しcsvファイルに特徴量を書き出そうと試みていますが以下のエラーが出現しています。わかる方教えていただきたいです。

Module 'google.longrunning.operations_pb2' has no attribute 'OperationsStub'によると、

googleapis-common-protos 1.6.0b6 を使っていてこの問題が発生し、googleapis-common-protos 1.5.3に入れ替えることでエラーが出なくなった、と書いてあります。

試してみてください。
