I am now happily using 0.3.2. The experience to get it working was absolutely awful. Still I was expecting better improvements node vs node-gpu. For a sample set that I used the difference is 16000ms vs 8000ms. So almost twice. Not bad but was expecting 10x.

With the latest tfjs-node/tfjs-node-gpu package, we are shipping pre-compile addon and there should be no compilation on your machine. This issue should have been fixed.
