Error when loading icevision in colab about icevision

[misza222]

The problem is with sahi library - they have changed the interface between version 0.10 and 0.11 and icevision 0.12 (most recent version on pip) relies on things that are only present in <= sahi 0.10.*

Hi,

I Encounter the same issue,

The Issue occurred when I tried to import --> from icevision.all import *

[/usr/local/lib/python3.8/dist-packages/icevision/models/inference_sahi.py](https://localhost:8080/#) in <module>

---> 14 from sahi.model import DetectionModel
     15 from sahi.prediction import ObjectPrediction
     16 from sahi.predict import get_sliced_prediction as sahi_get_sliced_prediction

ModuleNotFoundError: No module named 'sahi.model'

My Installation followed :

# # Torch - Torchvision - IceVision - IceData - MMDetection - YOLOv5 - EfficientDet Installation
!wget https://raw.githubusercontent.com/airctic/icevision/master/icevision_install.sh

# # Choose your installation target: cuda11 or cuda10 or cpu
!bash icevision_install.sh cuda11

then installed sahi

!pip install sahi -U
then I checked the versions of Icevision and sahi.

icedata 0.5.1
icevision 0.12.0
sahi 0.11.6

As the error is pointing to the icevision/models/inference_sahi.py file, I looked into it and modified as below:

from sahi import DetectionModel instead from sahi.model import DetectionModel

This solved the issue.
