Hi.
I generated Unet trt.engine file through export path. But I get following error while inference task:

Can you share your command and full log?

Hi. Sorry for being late

Can you modify above and try
/workspace/tlt/results/unet/export/inference

p.vahidinia · October 18, 2021, 10:33am

I tried but got the same result.

p.vahidinia · October 19, 2021, 4:14am

@Morganh please check this problem

Morganh · October 19, 2021, 5:19am

Did you run inference against pruned tlt model or unpruned tlt model?

p.vahidinia · October 19, 2021, 5:30am

I can run inference against unpruned model.
But according to this topic: Unet pruned model Inference error I can not inference against pruned model
