I found this issue when I was trying to figure out how to use my teachable machine model in Node.js. I thought I would comment in case others end up here wondering how to use their model in Node.js with Tensorflow.js. I created a starting template that might be helpful to others. (FYI it is not using the teachable machine library, only its exported trained model.)

Hi @tr7zw and @steamp0rt thanks for filing the issue. We are working on the savedmodel export it should be fixed soon.

And you’re right we have not implemented nodeJs support. It’s good to know that you would like to use it in this environment and we’ll keep it in mind for future planning.
