Describe the problem or feature request

Cannot import @tensorflow/tfjs-node-gpu at all, only @tensorflow/tfjs-node but I'd like to use my GPU.

Code to reproduce the bug / link to feature request

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

Here is the error:

`internal/modules/cjs/loader.js:977
return process.dlopen(module, path.toNamespacedPath(filename));
^

Error: The specified module could not be found.

I've tried reinstalling all my modules, tried using Recommended Node version, tried rebuilding the package, idk what else to try so I'm hoping to get some way to fix this from here

hi @Mobles, quick question: are you seeing the same issue when using @tensorflow/tfjs-node package?

[gobboo]

@kangyizhang Nope, that works fine, I have had that issue when using it once but I fixed it by doing
npm rebuild @tensorflow/tfjs-node --build-from-source

This doesn't fix it for tfjs-node-gpu though :/

hi @Mobles

Other users has the same issue and I'm dedicated to fixing it. However I can not reproduce it on my windows machine, I need some of your help.

Can you

1. Fork the @tensorflow/tfjs repo: https://github.com/tensorflow/tfjs
2. go to tfjs-node directory
3. add console.log('bindingPath: ', bindingPath); at this line: https://github.com/tensorflow/tfjs/blob/master/tfjs-node/src/index.ts#L29
4. run yarn && yarn test, this will print out the bindingPath value and start to run tests locally. You can need to wait for all the tests, fill free to Ctrl+c to terminate the tests.
5. paste the bindingPath value here

Thank you!
5.

bindingPath: D:\Programming\NodeJS Work\dumb-doorbell\server\test\tfjs\tfjs-node\lib\napi-v4\tfjs_binding.node

The tests failed anyhow

Failures:
1) computation in worker (node env) test-tensorflow {} tensor in worker
  Message:
    Error: Cannot find module './dist/index.js'

[kangyizhang]

Thanks a lot for the update!

The path looks fine. And if the test could start, the module could be loaded correctly. The problem should be related with the published npm package. I'll look into it.

FYI the failed test is unrelated.

[gobboo]

Ah okay, thanks for the assistance !

[kangyizhang]

@Mobles I can reproduce the issue. It's because of the space in your path. Space in path is not supported by the binding tool node-gyp. Please try to move it to a folder without space and let me know if the error still exist.

[gobboo]

Nope, same error, no spaces in my file path

[kangyizhang]

@Mobles did you delete node_module and reinstall dependencies?

[gobboo]

Yup, I deleted the folder and typed
npm install

[kangyizhang]

@Mobles can you try go to the @tensorflow/tfjs-node-gpu directory, like cd node_modules\@tensorflow\tfjs-node-gpu, then run node-pre-gyp rebuild (you might need to npm install -g node-pre-gyp). Then see if you can import tfjs-node-gpu?
