Unexpected identifier async _initialize()

[napindc]

I'm getting the below error when using this package. Is there anyway to fix this?

I'm using node 8.9.3. And it has worked locally... and had worked when I deployed it to Google's Firebase functions, but all of a sudden today I'm trying to deploy to firebase functions again, and I get this error. I hadn't run any npm install / update so not sure why this happened today.

Detailed stack trace: /user_code/node_modules/keras-js/lib/Model.js:107
  async _initialize() {
        ^^^^^^^^^^^

I have the same issue here. Any workarounds?

Suddenly started happening here as well. Did one of you manage to find away around this?

The runtime of Google Cloud Functions is Node v6.11.5, which does not support async/await.

https://cloud.google.com/functions/docs/writing/#the_cloud_functions_runtime

A possible workaround is using babel-register to transpile async/await on runtime, though I think keras-js should not use async/await (or at least should transpile them before releasing) until Node.js v6.x comes to the end of life (April 2019).

I found that keras-js does not even support the latest LTS (Node v8.x).

Is there any reason for that?

Run this npm uninstall ember-cli npm cache clean && bower cache clean npm install [email protected]
