Exported tensorflow model not working from yesterday

[kkannan1]

Please provide us with the following information: The codebase can't read the tensorflow model that I exported from Custom Vision portal from yesterday and today. The app is crashed while opening. If I given a old tensor flow model(.pb file) I exported few weeks back, it is working fine. Please help

This issue is for a: (mark with an x)

- [ X] bug report -> please search issues before submitting
- [ ] feature request
- [ ] documentation issue or request
- [ ] regression (a behavior that used to work and stopped in a new release)

Minimal steps to reproduce

Replace the model (.pb file) and labels in the asset folder and hit run.

This is true. This also happened to me with a model trained last Sunday, September 23.
