How can I fix compatibility problems with tfjs-node?-CodePudding

Importing

// Frontend - Vue.js
const tfn = require('@tensorflow/tfjs-node')

then running

npm install --save @tensorflow/tfjs-node

gets me followed error:

npm ERR! node-pre-gyp ERR! stack     at maybeClose (node:internal/child_process:1093:16)
npm ERR! node-pre-gyp ERR! stack     at Process.ChildProcess._handle.onexit (node:internal/child_process:302:5)

node-pre-gyp v1.0.9 / Windows 11 / Visual Studio Code

I need tfjs-node to load my local tensorflow model

const tfn = require("@tensorflow/tfjs-node");
const handler = tfn.io.fileSystem("./path/to/your/model.json");
const model = await tf.loadLayersModel(handler);

After installing npm i @tensorflow/[email protected] (Suggestion from @Vladimir Mandic):

CodePudding user response：

installer for @tensorflow/tfjs-node only tries build
if it cannot find and download prebuild binaries for a given platform
(and build process is anything but simple)

in your case, you're on windows x64 and using nodejs v16, so it should be ok

but...pre-build binaries for that platform for tfjs 3.19.0 are not correctly published
(you can check https://storage.googleapis.com/tf-builds/pre-built-binary/napi-v8/3.19.0/CPU-windows-3.19.0.zip and see the error directly)

tfjs team will fix it soon

but for the time being, i suggest to use tfjs-node 3.18.0 instead
(you can check https://storage.googleapis.com/tf-builds/pre-built-binary/napi-v8/3.18.0/CPU-windows-3.18.0.zip and see its fine)
