我刚开始研究 apache 超集。我想尝试超集提供的示例数据集。我运行了命令
superset load_examples
在虚拟环境中。执行->
No PIL installation found

似乎安装没有任何问题。现在，当我转到我的超集仪表板时，我找到 World Bank's Data 我点击它，所有图表都显示
No results were returned for this query. If you expected results to be returned, ensure any filters are configured properly and the datasource contains data for the selected time range.
然后我检查所有示例仪表板，所有仪表板都写了相同的内容。 我不知道可能是什么问题。有人可以帮忙吗？
