[BUG] **AttributeError: module 'fiftyone' has no attribute 'config'**

[syedrz]

import fiftyone as fo
import fiftyone.zoo as foz

dataset = foz.load_zoo_dataset(
  "coco-2017", 
  split="validation",
  label_types=["detections", "segmentations"],
  max_samples=5,
)
session = fo.launch_app(dataset)

I am running above code in notebook when I get following error

Little background,
I ran this on both colab and local notebook and faced same issues as mentioned below

When I try to import fiftyone
import fiftyone as fo

I got following error
ImportError: cannot import name '_registerMatType' from 'cv2.cv2' (/usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-x86_64-linux-gnu.so)

then I resolved it using
!pip uninstall opencv-python -y
!pip install opencv-python
!pip uninstall opencv-python-headless -y
!pip install opencv-python-headless==4.1.2.30

After this when I try to import fiftyone I get error
AttributeError: module 'fiftyone' has no attribute 'config'

The cv2 _registerMatType error can be resolved by following these instructions (which I see that you did in your follow-up message).

Note that you need to restart the notebook's runtime after reinstalling packages <-- I think this will resolve your issue.

Thanks for the instructions, Issue is resolved
