[BUG] Error while downloading coco dataset

[AliNaqvi110]

I get following error while downloading some classes of coco dataset, I tried to search but couldn't find anything
Error
module 'cv2' has no attribute '_registerMatType'

Here is the code I'm using

import fiftyone as fo
import fiftyone.zoo as foz

dataset = foz.load_zoo_dataset(
"coco-2017",
split="train",
label_types=["detection"],
classes=["person", "car", "bicycle", "motorcycle", "bus", "train", "truck", "traffic light", "stop sign"],
max_samples=50,
)
session = fo.launch_app(dataset)
session.dataset = dataset

kindly help me out, much appreciated

This is a Google Colab environment issue. #1494 has the solution.
