获取行数和字节大小
本指南向您展示如何使用数据集查看器的 /size 端点以编程方式检索数据集的大小。您也可以随意使用 ReDoc 试用它。
/size 端点接受数据集名称作为其查询参数
Python
JavaScript
cURL
import requests
headers = {"Authorization": f"Bearer {API_TOKEN}"}
API_URL = "https://datasets-server.huggingface.co/size?dataset=ibm/duorc"
def query():
response = requests.get(API_URL, headers=headers)
return response.json()
data = query()端点响应是一个 JSON，其中包含数据集的大小，以及每个子集和拆分的大小。它提供了不同形式数据的行数、列数（如果适用）和字节大小：原始文件、内存 (RAM) 大小和自动转换的 Parquet 文件。例如，ibm/duorc 数据集在其所有子集和拆分中共有 187,213 行，总大小为 97MB。

}如果大小具有 partial: true，则表示无法确定数据集的实际大小，因为它太大了。
在这种情况下，行数和字节数可能小于实际数字。
