Question use IL2CPP build Universal Windows Platform, but every time I obtain a bunch of error.

It can be built normally on the Windows platform, and an error will be reported on the UWP platform.
use IL2CPP build Universal Windows Platform, but every time I obtain a bunch of error.
who can help me.

the error message:

Tensor tensorNum = graph.OperationByName("num_detections");
Tensor tensorBoxes = graph.OperationByName("detection_boxes");
Tensor tensorScores = graph.OperationByName("detection_scores");
Tensor tensorClasses = graph.OperationByName("detection_classes");
Tensor imgTensor = graph.OperationByName("image_tensor");
Tensor[] outTensorArr = new Tensor[] { tensorNum, tensorBoxes, tensorScores, tensorClasses };
var results = sess.run(outTensorArr, new FeedItem(imgTensor, imgArr));

run method:
public virtual NDArray[] run(object fetches, params FeedItem[] feed_dict);


may be the problem is,run method need object type, and call it use Tensor[] type.
IL2CPP don't support this writing method,but it can be executed normally in unity.
In this case, do I need to modify the source code of TensorFlow to solve the problem,Pass exact Parameter type.

 

Code (CSharp):

1. Tensor tensorNum = graph.OperationByName("num_detections");
2. Tensor tensorBoxes = graph.OperationByName("detection_boxes");
3. Tensor tensorScores = graph.OperationByName("detection_scores");
4. Tensor tensorClasses = graph.OperationByName("detection_classes");
5. Tensor imgTensor = graph.OperationByName("image_tensor");
6. Tensor[] outTensorArr = new Tensor[] { tensorNum, tensorBoxes, tensorScores, tensorClasses };
7. var results = sess.run(outTensorArr, new FeedItem(imgTensor, imgArr));
8.  
9. run method:
10. public virtual NDArray[] run(object fetches, params FeedItem[] feed_dict);

Did you solved this?

 

Hello, did someone knows how to solve it?
