SAHI not compatible with Shapely==1.8.5

[DamianBisewski]

Hello, I would like to report an issue with the compatibility of the SAHI package with Shapely version 1.8.5.

In this configuration, when attempting to use sahi.utils.coco, the following error occurs:
from sahi import AutoDetectionModel
from sahi.predict import get_sliced_prediction, get_prediction
from sahi.utils.cv import read_image_as_pil
ImportError Traceback (most recent call last)
Cell In[27], line 2
1 from shapely.geometry import Polygon
----> 2 from sahi import AutoDetectionModel
3 from sahi.predict import get_sliced_prediction, get_prediction
4 from sahi.utils.cv import read_image_as_pil

File /opt/conda/lib/python3.10/site-packages/sahi/init.py:3
1 version = "0.11.16"
----> 3 from sahi.annotation import BoundingBox, Category, Mask
4 from sahi.auto_model import AutoDetectionModel
5 from sahi.models.base import DetectionModel

File /opt/conda/lib/python3.10/site-packages/sahi/annotation.py:9
5 from typing import Dict, List, Optional
7 import numpy as np
----> 9 from sahi.utils.coco import CocoAnnotation, CocoPrediction
10 from sahi.utils.cv import (
11 get_bbox_from_bool_mask,
12 get_bool_mask_from_coco_segmentation,
13 get_coco_segmentation_from_bool_mask,
14 )
15 from sahi.utils.shapely import ShapelyAnnotation

File /opt/conda/lib/python3.10/site-packages/sahi/utils/coco.py:17
14 from typing import Dict, List, Optional, Set, Union
16 import numpy as np
---> 17 from shapely import MultiPolygon
18 from shapely.validation import make_valid
19 from tqdm import tqdm

ImportError: cannot import name 'MultiPolygon' from 'shapely' (/opt/conda/lib/python3.10/site-packages/shapely/init.py)

The fix is trivial, just replace line 17 in sahi/utils/coco.py:
from shapely import MultiPolygon
with:
from shapely.geometry import MultiPolygon
This change will make SAHI compatible with Shapely 1.8.5 (and newer versions as well).
