Answer: It's not possible for me to know how many rows are in a specific SFrame without more information. The number of rows in an SFrame will depend on the data that it contains and how it was created.
Explanation: SFrame is a data structure for storing large amounts of data in a tabular format, similar to a spreadsheet or a SQL table. It was developed by the company Turi, which was later acquired by Apple. SFrames are designed to be efficient and scalable, and they can store data in a variety of formats, including numerical, categorical, and text data.
