tfjs: tfjs-node invalid installation/setup no such file or directory

Hi, @digimbyte

Thank you for helping us with above detailed details and will dig more into this issue. It’s good to hear that it’s working with @tensorflow/tfjs-node@3.1.0, if your issue got resolved please feel free to close this issue and for future update you can follow this issue https://github.com/tensorflow/tfjs/issues/7341 where we’ll update once we got the new update from our concerned team with latest version of @tensorflow/tfjs-node for Windows machine. Thank you!

I have a similar problem. After downgrading to nodejs version 18.17.0 and using npm install --save-exact @tensorflow/tfjs-node@3.1.0, I was able to get it installed. However, when I run my project, I instantly get this error:

node:internal/modules/cjs/loader:1340
  return process.dlopen(module, path.toNamespacedPath(filename));
                 ^

Error: The specified module could not be found.

  code: 'ERR_DLOPEN_FAILED'
}

I have no idea what this means. The tfjs_binding.node is present in that folder. I tried rebuiling the package locally with npm rebuild @tensorflow/tfjs-node --build-from-source, which succeeded, but I still got the same error. Is there a solution to this?

I have resolved this using this comment. The problem was the missing tensorflow.dll file in that napi-v7 folder.

I want to share my success installation with

• node == 20.11
• @tensorflow/tfjs-node-gpu == 4.16.0

1. npm i @tensorflow/tfjs-node
2. during installing, open another console and run this script to rename napi-v8 to napi-v9 folder

node rename.js

• rename.js

import fs from 'fs'
// const fs = require('fs')
while (true) {
  try {
    // change tfjs-node-gpu to tfjs-node
    fs.renameSync('./node_modules/@tensorflow/tfjs-node-gpu/lib/napi-v8', './node_modules/@tensorflow/tfjs-node-gpu/lib/napi-v9')
    break
  } catch (e) {

  }
}
console.log('done')

1. after install success, make sure to move all files in napi-v9 to napi-v8 node_modules\@tensorflow\tfjs-node-gpu\lib\napi-v8 should have both tensorflow.dll and tfjs_binding.node files

PS: Installation failed because of no target folder napi-v9, but create with mkdir -p node_modules/@tensorflow/tfjs-node-gpu/lib/napi-v9 before npn install is doesn’t work, so I have to create during installation instead.

I had been struggling with the same error, and I managed to resolve it. My system configuration is as follows:

Windows: 11 Node.js: 18.17.0 npm: 9.6.7 Python: 2.7

Here’s what I did to fix the issue:

Installed node-gyp globally:

• npm install -g node-gyp

Installed a specific version of @tensorflow/tfjs-node to avoid compatibility issues:

• npm install --save-exact @tensorflow/tfjs-node@3.1.0 By following these steps, I was able to successfully overcome the error. This might help others who are facing similar issues.

Something I found to work was renaming the node_modules/@tensorflow/tfjs-node/lib/napi-v8 mid-installation to napi-v9. The tensorflow.dll is then copied correctly and node will work correctly once you sync the files between the napi-v8 and napi-v9 directories.
