Hey Ravik, hope you are well!
I get the same error using Deepstream. From what I’m understanding the problem happens because the .plan was apparently created on a GPU different from the one I’m using to run the deepstream application (I’m on a TX2). But the .plan was created using tlt-convert on the gpu i’m using so i never switched gpus.
Any insight on what you did to solve the problem?
Have a nice day.
