我主要发现使用谷歌的客户端库易于使用，直观，非常适合惯用的python，除了auth之外（对于想出oAuth舞蹈的人来说，地狱中有一个特殊的地方）虽然在过去，我的大部分工作都是在Gsuite上，但我正在修改谷歌云客户端库，
寻找一个特定的图书馆我意识到他们现在有两种口味：gRPC和GAPIC。虽然两者都带有咸菜的一面，但我找不到任何关于哪种口味比另一种更好的参考，（如果有的话）。

另外，assistant API客户端只出现在gRPC中cloud-trace正好相反。
我应该选择哪个客户端库来开发我的应用程序？在惯用功能或性能方面是否存在任何重大差异？ （我希望gRPC库能够提高客户端的性能，但这是互联网，我们并不是所有的可靠带宽）所以，“ YMMV ”和“
文档没有指定选择哪种类型的效果，特别是当两种口味都在同一版本标签时。
非常感谢您的见解。

您真的不希望或者需要在其前面安装gapic-，proto-或grpc-的库。有一次，您真正想要的库将这些库用作依赖项。 （我们已经摆脱了这种行为，但由于历史原因，我们很可能会永久地停留在生活在PyPI上的那些包。）
您实际要安装的库拼写为google-cloud-{api}（例如google-cloud-speech，google-cloud-pubsub等。在少数情况下，这些可能使用您观察到的前缀来提取库，尽管现在几乎全部（如果不是全部）都应该删除它们。
如果您还有其他问题，请随时向我们issue tracker询问。
