使用自动档案器创建期望套件非常期待

Question

我是一个有着巨大期望的新手，正在尝试设置，但在使用Automated Profiler创建期望套件时遇到了以下问题。

C:Usersusergreat_expectations>great_expectations --v3-api suite new
Using v3 (Batch Request) API
How would you like to create your Expectation Suite?
1. Manually, without interacting with a sample batch of data (default)
2. Interactively, with a sample batch of data
3. Automatically, using a profiler
: 3
A batch of data is required to edit the suite - let's help you to specify it.

我也遇到了同样的问题，对我来说，问题来自于配置错误的数据源。我建议你做的是测试你的数据源配置，看看它找到了多少数据集：

from ruamel import yaml
import great_expectations as ge
context = ge.get_context()
datasource_config = {...}
context.test_yaml_config(yaml.dump(datasource_config))

运行此程序时，test_yaml_config将输出一个关于它找到了多少资产的报告。

如果它没有找到任何问题，那么当你试图在你的数据上创建一个套件时，你会遇到你所描述的问题。
