My apologies I should have included some more information to make things a tad easier.
If you git clone the project:
1) First do a "npm install"
2) Do "npm start react" and have it load in google chrome
3) Then press the "Enable Webcam" button, I end up with the following error:
The process_input() function is providing a tensor (as you can see), however, when I pass that to executeAsync() that looks like where the problem is happening. I keep getting the TypeError: Cannot read property 'backend' .. which is where I am at. The other TypeError in regards to the length is because of rejected promise from the executeAsync().
I am executing this on macOS Big Sur v11.2.1 on a MacBook Pro (13-inch, 2020).
I used tensorflowjs converter v3.3.0 to convert the saved model which was generated by Tensorflow v2.4.1.
Thanks,
Jake
