I’ve checked the specified directory/file and it exists.

Code to reproduce the bug / link to feature request

I’m trying the most basic example shown here: https://js.tensorflow.org/#getting-started

I have tfjs-node-gpu successfully installed on Windows. Tried both:

const tfGPU = require('@tensorflow/tfjs-node-gpu')
const tf = require('@tensorflow/tfjs')

And:

const tf = require('@tensorflow/tfjs')
const tfGPU = require('@tensorflow/tfjs-node-gpu')

@tensorflow/tfjs-node-gpu is required only once.

I have the same problem as @timbur, tfjs_binding.node is there but I got “Error: The specified module could not be found.”

I tied both CommonJS and ES6Modules:

const tf = require('@tensorflow/tfjs')
require('@tensorflow/tfjs-node-gpu')

and:

import * as tf from '@tensorflow/tfjs';
import '@tensorflow/tfjs-node-gpu';

I have Win10, Nodejs 11.2, Python 2.7. I tried VS2015 and VS2017, with both I get same error after install.

EDIT ------------------------------------------

after some struggles I found I out that I haven’t install required nvidia drivers and tools, so for those who have the same problem you must install CUDA Toolkit 9 (Not 10 for now) and cuDNN SDK for CUDA Toolkit 9 and append them to windows path which is explained in detail at this page: https://www.tensorflow.org/install/gpu

We ship 0.12.7 right now in the tfjs-node package. Sorry for the confusion - but you only have to npm install @tensorflow/tfjs-node today. That package ships with a supported version of @tensorflow/tfjs.

So basically this:

  "dependencies": {
    "@tensorflow/tfjs-node": "^0.1.17",
    ...
  }

// Package ships with '@tensorflow/tfjs':
const tf = require('@tensorflow/tfjs');
require('@tensorflow/tfjs-node');
