I am using a model

[Roboflow Demo](https://demo.roboflow.com/curly-hair/1?publishable_key=)(my key)

But I get  
index.ts:175 This model execution did not contain any nodes with control flow or dynamic output shapes. You can use model.execute() instead.

main.js:379 CAUGHT Error: Error in transpose: rank of input 1 must match length of perm 0,2,1.

Anyone knows how this can work?
