Following your quick guide
(adding concepts, uploading pictures with those concepts, creating a model and training the model),
My program steps through it without a problem until it gets to the training part, where it ends with the following status message:
"description":"Invalid model argument",
"details":"There are no concepts added to this model yet. Please add concepts to this model.",
I am on your Community plan right now, using 10 concepts (and made a test model with just one following the quick guide exactly - same result).
Hope you can help with this.
