tfjs: Error when trying to use tfjs-node on Windows 10

In my main.mjs file I have import * as tf from "@tensorflow/tfjs-node";.

I get this error when I try to run the file:

node:internal/modules/cjs/loader:1142
  return process.dlopen(module, path.toNamespacedPath(filename));
                ^

Error: The specified module could not be found.

As you can see from the log I made sure that it was using Python 2 instead of Python 3, but it still isn’t working. I’ve tried following the instructions here as well, but to no avail.

Why does this get closed again? The issue is still persisting on multiple platforms and node versions.

It kind of worked! So first, I installed node-pre-gyp globally, and then I ran node-pre-gyp rebuild in node_modules/@tensorflow/tfjs-node. I still got the same error when running node main.mjs. Then, I copied tensorflow.dll and tensorflow.lib from deps/lib to lib/napi-v6. Now I am getting this error:

tensorflow/core/platform/cpu_feature_guard.cc:142] Your CPU supports instructions that this TensorFlow binary was not 
compiled to use: AVX2

@Jwiggiff, @rthadur the issue shouldn’t be closed on a workaround involving to manually move files from node_modules subdirectories.

There’s a problem with Node.js N-api that should be fixed on Windows because many other users will get it soon.

The install script stops at napi v6 while recent Node.js versions use napi v7 (https://nodejs.org/api/n-api.html#n_api_n_api_version_matrix).

dll file isn’t linked properly because cp.exec('node scripts/deps-stage.js symlink ' + modulePath); in install.js generates running node scripts/deps-stage.js symlink ./lib/napi-v7 while tfjs_binding.node is stored in lib/napi-v6.

I think this is not related to windows because I see this issue on

I tried npm rebuild @tensorflow/tfjs-node build-addon-from-source with no luck.

UPDATE:

Seems like the issue was the white space in the project path. Something like /MyFolder/My Name/ always failed.

After about a day of research I stumbled across this thread (finally!). Turns out @Jwiggiff 's response worked for me as well:

RUN npm i -g node-pre-gyp && \
    cd /usr/src/app/node_modules/@tensorflow/tfjs-node && node-pre-gyp rebuild && \
    cp /usr/src/app/node_modules/@tensorflow/tfjs-node/deps/lib/* /usr/src/app/node_modules/@tensorflow/tfjs-node/lib/napi-v8/

As @jeanbmar has stated, however, I don’t think this issue should be closed. The above was the only thing that worked across several different versions node images (Docker).

  1. module_name problem solves with other runner, use node-pre-gyp rebuild
  2. You shoul manualy past files to node_modules/@tensorflow/tfjs-node/lib/napi-v6. Copy it from deps/lib
