Data.__init__() got an unexpected keyword argument 'is_load'

This error message suggests that there is an issue with the arguments passed to the __init__() method of the Data class. In particular, it seems that an unexpected keyword argument 'is_load' was passed to the method.

To resolve this issue, you need to check the definition of the Data class and make sure that the __init__() method accepts the 'is_load' argument. If it does not, you need to remove this argument from the call to the method.

Alternatively, if the 'is_load' argument is required, you need to update the definition of the Data class to accept this argument in the __init__() method.
