Hi, @satendra-cotginanalytics

Thank you for bringing this issue to our attention and I would suggest you to please follow below steps with Node v19.9.0 and different Python versions like 3.6, 3.7, 3.8, 3.9,3.10 or 3.11, if it did not work then please try with this specific versions Node v18.16.1, Pyhton 3.9.13, node-gyp 10.0.1, npm 9.5.1 and it should work

• Step 1-: Create new folder and move to that folder by using cd folder_name then run command npm init -y it will create empty Node.js project
• Step 2-: npm install -g node-gyp Or sudo npm install -g node-gyp
• Step 3-: Download the Visual Studio Build Tools and select the Desktop development C++ (keep it default settings option)
• Step 4 -: node-gyp configure --msvs_version=2017 Or sudo node-gyp configure --msvs_version=2017 (run this command and replace --msvs_version value with your downloaded Visual Studio build tool version)
• Step 5-: set npm_config_python="C:\path\to\python.exe" Or sudo set npm_config_python="C:\path\to\python.exe(Replace your python.exe path in double quotes )
• Step 6-: go to your project directory and try to install (npm install @tensorflow/tfjs-node Or sudo npm install @tensorflow/tfjs-node)

tfjs-node requires AVX processors and tfjs-node library uses AVX instructions to improve the performance of its operations. If your CPU does not support AVX, as far I know you will not be able to use tfjs-node if I'm not wrong so to check AVX support please follow below steps

• Right-click on the Start button and select "System Information."
• Expand the "Processor" category in the left-hand pane.
• Look for "Instruction Set" or "Extended Instructions" in the right-hand pane. If AVX is supported, you should see it listed there (e.g., "AVX2").

I tried from my end and tfjs-node installing successfully and I ran sample model training code and it's working as expected, for your reference I have added output log below :
