Internal error in Model Optimizer Converter

I'm trying to convert a Tensorflow model into IR. The model Mask RCNN Inception V2 and I didn't modify it. After running MO I receive the following output: 

[ ERROR ]  ----------------- INTERNAL ERROR ----------------

Dear Mikhail, 

it is the argument --output="num_detections,detection_masks,detection_boxes,detection_classes,detection_scores" which breaks the conversion, withdraw it and it will work. 

Best, 

Severine
