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.

The text was updated successfully, but these errors were encountered:

nkreeger · 2018-09-27T22:21:09Z

tfjs-node now ships with tfjs - so you don't need to npm install @tensorflow/tfjs. Can you show me the output from the command:

npm install @tensorflow/tfjs-node-gpu

Make sure you have Python 2.7 on windows - 3.x is not supported with node-gyp (build tool for Node.js addons).

If npm install @tensorflow/tfjs is no longer necessary, what is the correct require/import usage? Is it still the following?

const tf = require('@tensorflow/tfjs')

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

craftgear · 2018-09-28T13:42:17Z

Hi, I have the same problem with a different error message.

Registration of backend tensorflow failed
TypeError: backend.setDataMover is not a function

Once I remove node_modules/@tensorflow and install @tensorflwo/tfjs-node only then the error disappears.

I guess the reason I got above error was I first installed tfjs then add tfjs-node afterwords.
Maybe dependency versions unmet?

Anyway, thanks @nkreeger 👍

brannondorsey · 2018-09-28T16:11:18Z

I experienced a similar problem to @craftgear. I already had @tensorflow/tfjs as a dependency in a project and added @tensorflow/tfjs-node. This caused the registration of the tensorflow backend to fail. Removing the node_modules/ folder and reinstalling with npm install fixed the problem. Strangely, the project now works even with both dependencies:

  "dependencies": {
    "@tensorflow/tfjs": "^0.12.7",
    "@tensorflow/tfjs-node": "^0.1.17",
    "electron": "^2.0.8"
  }

nkreeger · 2018-09-28T16:32:02Z

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');

...

brannondorsey · 2018-09-28T16:35:59Z

@nkreeger thanks for that info. So it can be assumed that @tensorflow/tfjs will ship with @tensorflow/tfjs-node indefinitely (or if it is removed a breaking semver increment will be used) and projects using @tensorflow/tfjs-node should remove dependence on @tensorflow/tfjs explicitly, correct?

ghost · 2018-09-29T01:43:31Z

What about the GPU version? I'm still having the issue in my original post after a fresh install of only @tensorflow/tfjs-node-gpu.

Console output:

@timbur Can you try this:

cd node_modules/@tensorflow/tfjs-node-gpu
node-gyp build

Post the output here.

Also - might be easier to clone the tfjs-node repo and try running node-gyp build inside of that clone.

Also, the file is definitely there:

'C:/Users/me/Repos/predict/node_modules/@tensorflow/tfjs-node-gpu/build/Release/tfjs_binding.node'*

I wonder if I should try a fresh install of everything - i.e., node, npm, python, git bash, etc. I wonder if somehow things got borked because I did at one point have both python 2 and 3 installed (now only 2).

I have done what you said just only installing

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

then index.js with just

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

runned as .mjs

nkreeger · 2018-10-04T20:27:00Z

It looks like it is having trouble installing MSVS - according to the node-gyp docs, you can do either:

1). npm install --global --production windows-build-tools
2.) Install build tools manually - links on their README

When you invoke through node_modules - node_gyp tries to compile in your actual project directory. Might be easier to rm -rf node_modules and re-run yarn or npm install

@nkreeger I'm still getting that same error. It looks like it is also using a globally installed node-gyp package? Do you think that's a problem, and should I remove it from the global package?

Thank you very much for your help. 🤗

rahbari · 2018-11-17T13:12:18Z

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

nkreeger · 2018-11-28T00:18:05Z

It looks like you are running inside JetBrains? If so - can you try running through that command prompt that you installed with? I wonder if a path is not working correctly in the JetBrains IDE.

xiaodeaux · 2018-12-06T08:21:30Z

@rahbari Thanks for your edit pointing out that the software libraries need to be installed as prerequisites. I guess I just glanced over that or ignored it. I'm doing that now and I'm confident that will solve the issue I'm having. I should have read the documentation more closely. ❤👀

rahbari · 2018-12-06T17:52:07Z

@nkreeger I hadn't installed CUDA SDK, after installing everything works fine in Intellij.

happy-machine · 2019-01-16T14:05:31Z

Hi i'm getting the same error here in 2019! Would appreciate some help, about to go into production

Thanks!

Hi

I've just installed a new aws ec2 instance of an api that serves predictions from a node API, node version is 8.13 which has worked for me previously on the same instance, but after pulling a newer version of the codebase i am now getting this error:

cc @nkreeger . Have you tried removing node_modules, and re-running yarn/npm to re-install the tfjs-node dependency? Looks like the TF C++ library is missing in node_modules/.

happy-machine · 2019-01-16T16:59:51Z

Hey .. that nailed it thanks, reinstalled tfjs-node, all working fine now : )

Yes. I removed node_modules folder and reinstall modules including @tensorflow/tfjs-node that works.

ghost · 2019-01-31T00:05:04Z

Can someone please explain step by step how to get the gpu version to install on a fresh windows 10? I have everything else installed properly afaik and it still craps out at the node-gyp rebuild step of install.js with no information whatsoever on what the problem is. The plain node version installs fine. It’s been 4 months.

ghost · 2019-01-31T02:19:15Z

Yeah I officially give up. I can’t believe how bad this node-gyp stuff still is in 2019. Is it easier to use the gpu version on Linux or something?

Also, why is the rebuild step even required? Why doesn't it come with whatever is needed, precompiled?

This is the error I see no matter what:

kir486680 · 2019-05-18T04:39:31Z

I am facing the same issue. I am using react native and It works fine when i import it import * as tf from '@tensorflow/tfjs'; It works fine when i create a model but when i do const xs = tf.tensor2d([[1], [2], [3], [4], [5], [6], [7]], [7, 1]); I get Error: Could not initialize any backends, all backend initializations failed . I tried to reinstall tfjs by removing node_modules folder several times and it still doesn't help. (installing tfjs doesn't geive me any errors)

Version used: "@tensorflow/tfjs": "^1.1.2"

nkreeger · 2019-05-28T17:40:22Z

@kir486680 We don't officially support React Native - it is something we're planning on investigating soon.

============================
Hi there 👋. Looks like you are running TensorFlow.js in Node.js. To speed things up dramatically, install our node backend, which binds to TensorFlow C++, by running npm i @tensorflow/tfjs-node, or npm i @tensorflow/tfjs-node-gpu if you have CUDA. Then call require('@tensorflow/tfjs-node'); (-gpu suffix for CUDA) at the start of your program. Visit https://github.com/tensorflow/tfjs-node for more details.
