[TensorRT] ERROR: UffParser: Parser error: 'Unsupported binary op sub with constant left'

I am using TensorRT- I have successfully convert my TensorFlow frozen graph to uff model. However, when I was trying to convert uff to trt_engine, an error raised: ‘Unsupported binary op sub with constant left’. Specifically, the operation is:

A - B
, where A is a Const (previously a tf.Variable, frozen to Const) of size [1, 1, 1, 32, 112], 
and B is a Tensor of size [1, 15, 24, 1, 112].

Any idea how to solve this?
