I'm sorry, but I need more context to understand what you mean by "could not perform checkpoint". Can you provide more information about the issue you are facing?

flink could not perform checkpoint 2 for operator Co- Process- Broadcast- Keyed

这个错误通常是由于某些原因导致 Flink 无法完成算子的检查点操作，可能的原因包括：

1. 算子状态太大，无法写入到持久化存储中，导致检查点失败。
2. 持久化存储出现故障，无法写入状态数据。
3. 网络故障或者资源不足导致任务无法正常执行。

为了解决这个问题，你可以尝试以下几个步骤：

1. 检查算子状态大小，如果状态太大可能需要进行优化，例如减少状态的数量或者使用压缩算法来减小状态大小。
2. 检查持久化存储是否正常工作，可以尝试使用其他存储方案或者重新启动存储服务来解决问题。
3. 检查网络和资源使用情况，确保集群资源充足并且网络连接正常，尝试调整资源分配来解决问题。

如果以上步骤无法解决问题，你可以尝试查看 Flink 的日志文件来获取更多信息，或者向 Flink 社区寻求帮助。

ValueError: operands could not be broadcast together with shapes (370,370) (2,)

This error occurs when trying to perform an operation that involves two arrays with incompatible shapes. In this case, the first array has a shape of (370,370) while the second array has a shape of (2,).

To fix this error, you need to ensure that the shapes of both arrays are compatible for the operation you are trying to perform. You can do this by either reshaping one or both arrays or by using a different operation that is compatible with the shapes of the arrays.
