I manage to show my dahua IP cam frames in an image-preview node.
Now I like to do object detection on every frame with yolo or tensorflow and coco nodes.
All nodes mentioning tensorflow or yolo that I found in the palette seem not possible to install.
I use node-red 3.1.7 and got the errors below :
Does someone have an idea why all nodes can not be installed without problems? Thx!

searching this ↑ lead to this: Cant install on windows 11 · Issue #7793 · tensorflow/tfjs · GitHub which says it is a known issue & to use an earlier version of nodeJS. Note it does say use v19 or v18 but Node-RED is not tested against V19 (so if you intend on rolling back Node version, chose v18)
Lastly, this is not an issue on Linux. If you have a different computer running linux then that would be my first recommendation.
In the link @Steve-Mcl posted it is written "use Node.js v18.16.1" while you say you have v18.20.3 so next I would do is to get that node.js version and check if that helps
