Change input shape of a TensorFlow computational graph

Description

I have a simple neural network written in TensorFlow 1.15 that I need to convert to a TensorRT optimized plan using tensorRT_optimizer tool which is inside DriveWorks SDK 1.2 in DRIVE PX2. The tool requires that the input dimensions be CXHXW. But the input dimensions of the TensorFlow models always have the batch dimension as the first dimension. Therefore, always the input dimensions are in the shape of BxCxHxW. Is there a way to remove this batch dimension from the TensorFlow computational graph only for inference?

You can see that the input dimension is 1x28x28.

Could you try always passing batch size 1 and your input in the 1xCxHxW dimension?
