Unable to load Node backend for Tensorflow (TypeError: Cannot read property 'nonMaxSuppressionV3Impl' of undefined)

I'm trying to use face-api.js facial recognition functions, which would run a lot faster with an installed Node backend. I've installed the backends with npm as below:

$ node -v
v14.1.0
$ npm list @tensorflow/tfjs-node
[email protected] /Users/akoi/Dev/bwr
└── @tensorflow/[email protected] 
$ npm list @tensorflow/tfjs
[email protected] /Users/akoi/Dev/bwr
├── @tensorflow/[email protected] 
├─┬ @tensorflow/[email protected]
│ └── @tensorflow/[email protected]  deduped
└─┬ @tensorflow/[email protected]
  └── @tensorflow/[email protected]  deduped

The face-api.js functions all work fine, just slow since the backend is not loading.

When I do attempt to load the backend according to the instructions, using:

require('@tensorflow/tfjs-node');

Here is the error I get when run:

TypeError: Cannot read property 'nonMaxSuppressionV3Impl' of undefined
    at Object.<anonymous> (/Users/akoi/Dev/bwr/node_modules/@tensorflow/tfjs-backend-cpu/dist/tf-backend-cpu.node.js:268:47)

    at Module._compile (internal/modules/cjs/loader.js:1176:30)
    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1196:10)

Any ideas? I've seen a similar issue raised last week, but no responses. All help and advice appreciated. Many thanks.

I have the same error with fresh installs. There were 2 issues happened to me.

First, Native Modules installation failed. I noticed my installation of @tensorflow/tfjs-node didn't installed successfully, even though NPM returns 0 exit code.

node-pre-gyp install failed with error: Error: Command failed: node-pre-gyp install --fallback-to-build

Since I'm using MacOS on installation, so I end up have to reinstall my XCode tools in order to fix the native modules binding.

sudo rm -rf $(xcode-select -print-path)
xcode-select --install

Second, Peer dependencies are not installed together with @tensorflow/tfjs-node.

npm WARN @tensorflow/[email protected] requires a peer of @tensorflow/[email protected] but none is installed. You must install peer dependencies yourself.
npm WARN @tensorflow/[email protected] requires a peer of @tensorflow/[email protected] but none is installed. You must install peer dependencies yourself.
npm WARN @tensorflow/[email protected] requires a peer of @tensorflow/[email protected] but none is installed. You must install peer dependencies yourself.
npm WARN @tensorflow/[email protected] requires a peer of @tensorflow/[email protected] but none is installed. You must install peer dependencies yourself.
npm WARN @tensorflow/[email protected] requires a peer of @tensorflow/[email protected] but none is installed. You must install peer dependencies yourself.

After installing the peer dependencies @tensorflow/[email protected], I'm able to get rid of the error.

Hope my experience helps! Cheers
