I’m trying to fine tune RT-DETR on a custom dataset using the example [notebook](https://github.com/NielsRogge/Transformers-Tutorials/tree/master/RT-DETR), but I’m getting the following error. `'MeanAveragePrecision' object has no attribute '_iou_type'` when I scroll up in the exception chain I see this is triggered by a different exception from the following code area. ` if not _TORCHVISION_AVAILABLE: raise ModuleNotFoundError( f"Metric `{self._iou_type.upper()}` requires that `torchvision` is installed." " Please install with `pip install torchmetrics[detection]`." )`  
I have installed both torchvision and torchmetrics detecion though. This is my results from pip show

Does anyone have any advice on how to resolve this? I am also running python 3.12

For anyone who finds this I couldn’t figure out the source of the environment issue. I switched to python 3.11 though and created a new environment. I tried installing everything again and then everything ran correctly.
