OpenCV in lambda-stack - non-gpu?

It seems like opencv is installed through the lambda-stack. (see e.g. here: Lamdastack Quick Introduction/ FAQ - Technical Help - DeepTalk - Deep Learning Community). However, when I try to import it, it seems to be a non-cuda-version of opencv:

>>> import cv2
>>> cv2.cuda.getCudaEnabledDeviceCount()

Is that so, and how do you recomend installing OpenCV?

OpenCV GPU has to be installed manually and is to my knowledge not included in Lambda Stack. Here’s an article explaining it: How to install OpenCV 4.2.0 with CUDA 10.1 on Ubuntu 20.04 LTS (Focal Fossa) | by Shitty Bots | Medium
