Unexpected data type <class 'float'>

这个错误通常出现在代码试图处理`float`类型的数据，但是实际数据类型不是`float`类型。这个错误的原因可能是数据类型被错误地转换为了`float`类型，或者是数据在处理过程中出现了异常，导致数据类型发生了意外的变化。

解决这个错误的方法是检查代码中的数据类型转换操作，确保数据类型转换正确。另外，还需要检查数据处理过程中是否存在异常情况，例如除以0等非法操作，这些操作可能导致数据类型发生意外的变化。最好的方法是在程序中增加必要的异常处理机制，以应对这些异常情况的发生。

Unexpected data type <class 'numpy.int64'>

This error occurs when a variable or value is of a data type that is not compatible with the operation or function being used.

For example, if a function is expecting a float value but instead receives an integer value, it may raise this error.

To resolve this error, you can try converting the variable or value to the correct data type using functions like int(), float(), str(), etc. or by using appropriate data types in your code.

Exception: Unexpected data type <class 'numpy.int64'>

This exception occurs when a function or operation expects a certain data type, but receives a different data type. In this case, the function or operation may be expecting a different data type, but it receives a numpy.int64 data type instead.

To resolve this exception, you can try converting the data type to the expected type using the appropriate function. For example, if the function expects a float data type, you can use the float() function to convert the numpy.int64 data type to a float data type.

Alternatively, you can check the input data and make sure that it is in the correct format before passing it to the function or operation. This can help avoid unexpected data type errors.
