Multiple loadHandlers registered in node

TensorFlow.js version

“@tensorflow/tfjs”: “1.0.2”, “@tensorflow/tfjs-node”: “1.0.2”, “@tensorflow-models/universal-sentence-encoder”: “1.0.1”,

Browser version

It exhibits in node.js though the issue itself may be in core.

Describe the problem or feature request

Using the above packages and the code below you get the following error.

UnhandledPromiseRejectionWarning: Error: Found more than one (2) load handlers for URL 'https://storage.googleapis.com/tfjs-models/savedmodel/universal_sentence_encoder/model.json'

Multiple load handlers are being registered. This isue dows not occur with union package 1.0.1

Code to reproduce the bug / link to feature request

const tf = require('@tensorflow/tfjs-node');
global.fetch = require('node-fetch');
const useLoader = require('@tensorflow-models/universal-sentence-encoder');

(async function run() {
  console.time('Loading Universal Sentence Encoder');
  const use = await useLoader.load();
  console.timeEnd('Loading Universal Sentence Encoder');
})()

FYI this should be fixed in 1.1, we might have to update USE.

Hi, I meet similar problems when run PoseNet model with latest TFJS code. The errors are:

Uncaught (in promise) Error: Found more than one (4) load handlers for URL 'https://storage.googleapis.com/tfjs-models/savedmodel/posenet/mobilenet/quant2/075/model-stride16.json'

And How I run into this:

git clone https://github.com/tensorflow/tfjs.git && ^
cd tfjs && ^
yarn  & cd tfjs-core  && ^
yarn && yarn build-npm  && ^
yarn link  && ^
cd ../tfjs-converter  && ^
yarn && yarn build-npm  && ^
yarn link  && ^
cd ../tfjs-backend-cpu  && ^
yarn && yarn build  && ^
yarn link  && ^
cd ../tfjs-backend-webgl  && ^
yarn && yarn build  && ^
yarn link  && ^
cd ../tfjs-backend-webgpu  && ^
yarn && yarn build  && ^
yarn link  && ^
cd ../../    && ^
git clone https://github.com/tensorflow/tfjs-models.git && ^
cd tfjs-models  && ^
yarn    && ^
cd posenet    && ^
yarn link "@tensorflow/tfjs-core"   && ^
yarn link "@tensorflow/tfjs-backend-webgpu"   && ^
yarn link "@tensorflow/tfjs-converter"   && ^
yarn link "@tensorflow/tfjs-backend-webgl"   && ^
yarn && yarn build-npm   && ^
yarn link   && ^
cd demos   && ^
yarn link "@tensorflow/tfjs-core"   && ^
yarn link "@tensorflow/tfjs-backend-webgpu"   && ^
yarn link "@tensorflow/tfjs-backend-webgl"   && ^
yarn link "@tensorflow/tfjs-converter"   && ^
yarn link "@tensorflow-models/posenet"   && ^
yarn && yarn build   && ^
yarn watch

At first, I suspect some thing is wrong with my local environment. So I remove all links inside C:\Users\axing\AppData\Local\Yarn\Data\link, then delete all C:\Users\axing\AppData\Local\Yarn\Cache\v6\npm-@tensorflow-*

However, this still not work.
