Unable to install tfjs-node behind corporate proxy

Question

I made a tfjs solution for object detection and want to deploy it on server behind corporate proxy.

Problem happens because tensorflow\tfjs-node\scripts\install.js does not supprot proxy so it tries to fetch the https://storage.googleapis.com/tensorflow/libtensorflow/libtensorflow-cpu-windows-x86_64-1.15.0.zip directly from server and that isn't possible.'

I've set up my npm config

$npm config list

and console.log is:

; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/6.14.4 node/v12.18.0 win32 x64"
; userconfig C:\Users\user\.npmrc
https-proxy = "http://182.192.254.44:8080/"
proxy = "http://182.192.254.44:8080/"
python = "="
registry = "http://registry.npmjs.org/"
strict-ssl = false
; builtin config undefined
prefix = "C:\\Users\\user\\AppData\\Roaming\\npm"
; node bin location = C:\Program Files\nodejs\node.exe
; cwd = C:\IPA\beauty\TrackingServerProject
; HOME = C:\Users\usename
; "npm config ls -l" to show all defaults.

As you can see i get next error because of proxy.

$ npm install @tensorflow/tfjs-node
> @tensorflow/[email protected] install C:\IPA\beauty\TrackingServerProject\node_modules\@te
> node scripts/install.js
CPU-windows-2.0.1.zip

I think that i maybe need to change tensorflow\tfjs-node\scripts\install.js to add proxy ?

Please help!

Answer 1

I managed to get it to work after 3 days problem was in definition of PROXY

tensorflow\tfjs-node\scripts\resources.js (https://github.com/tensorflow/tfjs/blob/master/tfjs-node/scripts/resources.js)

line 40 & 41

const proxy = process.env['HTTPS_PROXY'] || process.env['https_proxy'] ||
      process.env['HTTP_PROXY'] || process.env['http_proxy'] || '';

When define proxy in ways 1) or 2) it doesn't detect process.env

1. npm config edit
2. .npmrc

So you need to pass system variable for PowerShell in form of $env:HTTP_PROXY="http://182.192.254.44:8080/"

or for CMD HTTP_PROXY=http://182.192.254.44:8080/

so it will work

just type: npm install @tensorflow/tfjs-node and enjoy!
