Vscode Extension failed because it can not locate bindings file when importing faiss-node

[masasso]

Describe the bug I am just trying to use the code provided in documentation inside the VSCODE extrension but I get the error below:

Code:

const { IndexFlatL2 } = require('faiss-node');

const dimension = 2;
const Faissindex = new IndexFlatL2(dimension);

console.log(Faissindex.getDimension()); // 2
console.log(Faissindex.isTrained()); // true
console.log(Faissindex.ntotal()); // 0

// inserting data into index.
Faissindex.add([1, 0]);
Faissindex.add([1, 2]);
Faissindex.add([1, 3]);
Faissindex.add([1, 1]);

console.log(Faissindex.ntotal()); // 4

const k = 4;
const results = Faissindex.search([1, 0], k);
console.log(results.labels); // [ 0, 3, 1, 2 ]
console.log(results.distances); // [ 0, 1, 4, 9 ]

Error:

@masasso Thank you for reporting the issue. I tried the above steps but didn't reproduce. From the runtime error logs, it seems that the compiled binary was not found.

Please try these options

• Create a blank nodejs project, install faiss-node, and run the given code see if it works. This is to confirm whether the problem is related to VS Code Extension.
• Provide detailed npm install faiss-node --verbose logs to troubleshoot whether the installation of prebuild packages failed.
• Please provide the smallest reproducible VS Code project for investigation.
• Try to compile the binary locally.

@masasso I got similar problems with OSX setup. I tried clean install and tested the example. I got an error indicating there is something "missing".... Library not loaded: '/usr/local/opt/libomp/lib/libomp.dylib' After "brew install libomp"... example works as expected. Note I've OSX not pure linux,... I hope this helps.

@tro9999 libomp is a dependency under OSX, I have bundled it in https://github.com/ewfian/faiss-node/pull/5 and a new version will be released.

I just ran into this issue too because bindings seemed to be looking for the .node file starting from the wrong directory as shown in the first comment. After digging through a bunch of other issues on google this one from node-bindings lead to a working solution https://github.com/TooTallNate/node-bindings/issues/43

Just add faiss-node as an external in the webpack config.

  externals: {
    // modules added here also need to be added in the .vscodeignore file
    "faiss-node": "commonjs faiss-node",
  },

then the sample code above and my own code using Faiss worked fine in a VSCode extension.
