Seeing issues running inference using tensorrt. How to fix it.

Tensorrt version 7.1.3
Torch version - 1.4.0

Hi, you were not able to build an engine.

Sadly, I do not have the capacity to help you debug this issue with tensorRT, as this is not something I'm not that experienced with.
If you are not familiar with TensorRT, I recommend you to use the default pytorch version.

@hukkelas what is the Tensorrt version you are using?

The issue is fixed by increasing the workspace size. I am using TRT 7
