An error occurred while attempting to couple OpenFoam with a machine learning model

Hello everyone.

I attempted to update the source item location in the flame table and replaced it with neural network inference. The compilation was successful, but the following error occurred while updating the item. I don't know where the problem occurred. It should have been an error reported when establishing the Tensor.

Here are the error content and interface content

Segmentation error means that you are trying to access memory that has not been allocated. This is perhaps something like you are trying to access a pointer that has not been assigned, or an index in a list that does not exist.
In your figure 3, in line 59 the loop looks weird. Why use i<1? Where is inputs_ defined? Seems to be an error with that. Maybe add some print checks or use a debugger (Build OPENFOAM from Source and Debug with VisualCode).
