Issue with custom object detection in the browser using tfjs

Hello, I was wondering if there is a blog or video tutorial that showed us how to do custom object detection in the browser using the most latest versions of tfjs. I tried kangaroo detector and SKU one, but when I tried to load custom models, it did not work, so I believe there may be a version mismatch issue. Alternatively, is there any way that I can use the old object detection api?
