大佬，机器学习PAI报这个错误，怎么解决？

这个错误是一个索引错误（IndexError），它通常发生在代码中尝试访问列表或数组的索引超出范围时。要解决此错误，你可以考虑以下几个步骤：
1. 确认索引值是否正确：检查代码中出现错误的地方，确保索引值没有超出列表或数组的有效范围。索引通常从0开始计数，因此最后一个元素的索引应为长度-1。
2. 检查数据结构：确保你正在使用正确的数据结构来存储和访问数据。如果是一个列表或数组，确保元素的数量和索引的顺序是一致的。
3. 检查循环和迭代操作：如果错误发生在循环或迭代过程中，确保循环变量或迭代器的范围正确，并在每次迭代时保持更新。
4. 输出调试信息：在错误发生处添加一些调试语句，输出相关变量的值，以便更好地理解问题所在。你可以打印出相关的索引、列表长度或其他相关变量，以帮助你找到错误。
5. 查阅文档和示例代码：查看相关库或框架的文档和示例代码，确保你正确使用了相应的函数和方法。特别是针对报错位置附近的代码行进行仔细研究，看是否有遗漏或错误的使用方式。
通过以上步骤，应该能够定位并解决索引错误。如果你仍然无法解决问题，请提供更多的代码细节和相关上下文，以便我可以提供更具体的建议和帮助。

可能是tf1/tf2的版本兼容性问题；可以试下tf1.x 版本或者在开头if tf.version >= '2.0':
```
tf = tf.compat.v1，此回答整理自钉群“【EasyRec】推荐算法交流群”
```
