execute() / excuteAsync() bug

[WinterTaoTao]

When I tried to implement a model converted from tensorflow frozen model, the execute() method gave me an Error said

tf-converter.esm.js?1e04:17 
Uncaught (in promise) Error: The model contains control flow or dynamic shape ops, please use executeAsync method
    at e.execute (tf-converter.esm.js?1e04:17)
    at VueComponent._callee$ (TensorFlowJsTry.vue?dd89:50)
    at tryCatch (runtime.js?4a57:62)
    at Generator.invoke [as _invoke] (runtime.js?4a57:296)
    at Generator.prototype.(:8080/anonymous function) [as next] (webpack-internal:///./node_modules/regenerator-runtime/runtime.js:114:21)
    at step (asyncToGenerator.js?7b11:17)
    at eval (asyncToGenerator.js?7b11:28)

But when I replaced the execute() method with executeAsync(), it gave me an Error said

tf-converter.esm.js?1e04:17 
Uncaught (in promise) Error: The model does not contain control flow or dynamic shape ops, please use execute method for better performance.

    at tryCatch (runtime.js?4a57:62)

Any idea about what happened?

Can you guys push this version on NPM?
