tensorflow/tfjs v1.1.0

1.1.0

on GitHub

High-level additions

• HTTP requests for models is now stable in browser / Node.js. You can use tf.util.fetch() for cross-platform fetch.
• Layers new layers: Conv3D, Noise
• Started development on a WebGPU backend. This is a preliminary prototype and will not be added to tfjs-core until it is stable and lands in all browsers.
