Hi, While running:

## clone the pytorch repository to setup exact directory structures as the original trained
!git clone https://github.com/pytorch/vision.git
%cd vision
!git checkout v0.3.0

!cp references/detection/engine.py ../
!cp references/detection/transforms.py ../
!cp references/detection/utils.py ../
!cp references/detection/coco_utils.py ../
!cp references/detection/coco_eval.py ../

   ## imports from the pytorch repo

import utils import transforms as T from engine import train_one_epoch, evaluate

i am getting error:

---------------------------------------------------------------------------

NOTE: If your import is failing due to a missing package, you can manually install dependencies using either !pip or !apt.

Hi , they seem to have removed the module , please refer to this. - https://github.com/pytorch/pytorch/pull/94709. The error seems to have come from "evaluate". The evaluate module from engine can be replaced by model eval or any other custom evaluation method. Let me know if this helps.

ate module from engine can be replaced by model

Got it, is it possible you can fix the code on your git repo to make it easier. Thanks
