使用“SQL Server 计算上下文”时,将在服务器上执行该代码。 如果从 SQL Server 获取数据,则数据应该是运行分析的服务器的本地数据,因此不会引入任何网络开销。 如果需要从其他源导入数据,请考虑预先安排 ETL。 处理大型数据集时,始终应该使用 SQL 计算上下文。
这就需要protoc,协议缓存编译器,来生成Python(或其它语言)的访问类。注意,要使用的缓存协议的定义已经编译好了,它们的Python类是TensorFlow的一部分,所以就不必使用protoc了。你需要知道的知识如何使用Python的缓存协议访问类。为了讲解,看一个简单的例子,使用访问类来生成Person缓存协议:...
