Seems like a bug with coco-ssd example

Code to reproduce the bug / link to feature request

Fairly new to tensorflow js. and was trying out this example: https://github.com/tensorflow/tfjs-models/blob/master/coco-ssd/demo/test_inline.html
Getting this error when it goes into model.detect:
tfjs:2 Uncaught (in promise) Error: TensorArray : Could not write to TensorArray index 0,
because the value dtype is int32, but TensorArray dtype is float32.

Not a bug, just a compatibility problem. While they don't update to the newest tfjs make sure you have the version 0.13.5 .
"dependencies": { "@tensorflow-models/coco-ssd": "0.1.1", "@tensorflow/tfjs": "0.13.5" }

Also a duplicate #1190

Thanks for pointing me to version numbers.
Seems like "@tensorflow/tfjs": "0.13.5" did not return any predictions.
It worked with "@tensorflow/tfjs": "0.13.1"
