This guide is for preparing your Windows 10 machine for computer vision in Node-RED with "tfjs-node-gpu" and canvas modules. GPU support requires Windows 10 PC with CUDA compatible NVIDIA GPU. If you skip CUDA installations, Tensorflow should fall back to CPU backend.
After running all commands you should have following versions of the components and be able to make predictions on images.
| Software | Version | Link |
|---|---|---|
| CUDA | 11.6.0_511.23 | https://developer.nvidia.com/cuda-downloads |
| cuDNN | 8.3.2.44 | https://developer.nvidia.com/cudnn |
| node-red | 3.0.2 | https://www.npmjs.com/package/node-red |
| node.js | 16.13.2 | https://nodejs.org/en/ |
| tfjs-node-gpu | 3.13.0 | https://www.npmjs.com/package/@tensorflow/tfjs-node-gpu |
| canvas | 2.8.0 | https://www.npmjs.com/package/canvas |
PC setups which I have successfully used:
-
Dell Laptop, Intel Core i7-8850H @ 2.60 GHz, Windows 10, 16 GB RAM, NVIDIA Quadro P600 (511.09)
-
Dell Laptop, Intel Core i7-11850H @ 2.50 GHz, Windows 10, 32 GB RAM, NVIDIA RTX A3000 Laptop GPU (522.06)
Download CUDA 11 toolkit and run installer.
Download cuDNN 8 package and install files.
Add following paths to PATH environment variable:
C:\Program Files\NVIDIA\CUDNN\v8.3\bin
C:\Program Files\NVIDIA\CUDNN\v8.3\lib\x64
Download ZLIB DLL
Extract to C:\zlib123dllx64
Add following path to PATH environment variable
C:\zlib123dllx64\dll_x64
Install with all options and addons.
npm install -g --unsafe-perm node-red
cd c:\users\<your-user-name>\.node-red
npm install @tensorflow/tfjs-node-gpu@3.13.0
cd c:\users\<your-user-name>\.node-red
node
var tf = require('@tensorflow/tfjs-node-gpu')
You should see something like this:
Download and install libjpeg-turbo-2.1.4-vc64.exe to folder C:\libjpeg-turbo64
Download and install GTK 2 64bit to folder C:\GTK
Execute following commands
cd c:\users\<your-user-name>\.node-red
npm install canvas
cd c:\users\<your-user-name>\.node-red\node_modules\canvas
node-gyp configure
node-gyp build
If you encounter issues during installation, see these links:
- https://sharp.pixelplumbing.com/install#canvas-and-windows
- https://github.com/Automattic/node-canvas/wiki/Installation:-Windows
Start Node-RED from command line or configure Node-RED to start at boot
https://nodered.org/docs/faq/starting-node-red-on-boot
This example uses SSD MobileNet v2 320x320 model from TensorFlow 2 Detection Model Zoo. Model is used directly in savedemodel format.
cd /.node-red
npm install node-red-contrib-image-info
npm install node-red-node-exif
npm install node-red-contrib-browser-utils
npm install node-red-contrib-image-output
node-red-start
Download example model and unzip to /.node-red/savedmodel
https://tequ-files.s3.eu.cloud-object-storage.appdomain.cloud/example_savedmodel.zip
Screenshot after example flow is deployed and image with two dogs is injected to flow.
Copy and import this flow into your Node-RED workspace.

Loading the model might take 1-3 minutes
-
Configure "[AI] Detect-sm" model_folder to match folder where you downloaded the example model.
-
Inject image to flow and start detecting objects.
-
First inference is slow and can take something like ~5-30 seconds. After that it should run smoothly. Max fps depends of image size and machine you are using.
If you need to build your own model, you can follow this guide:
