Describe the problem or feature request

Prior to upgrading tfjs-core, the process was working smoothly. A user takes a picture of an image, it will identify the image accordingly. No problem.

After upgrading to the latest versions, there seems to be a "delay" in identifying the images. For example: A user takes a picture of a hotdog (first time loading the page) the result is unknown. Then takes another picture of a pizza, the result is pizza. Then takes another picture of beer, the result is beer.

I didnt change anything in the codes, only upgraded tfjs-core. Am I missing something here?

All good now. I was doing self.mobileNet.predict(self.IMAGE) without doing a then() which screwed up the prediction timing.
