There's an error when running with upgraded tfjs-backend-wasm with both enabled SIMD and Threads flags. Please see detail info here.

Performance data (ms) of MobileNet v2 TFLite on ICL Acer Swift 3 (CPU: i5-1035G4, GPU: Intel Iris Puls Graphics)

Model	Wasm (Plain)	Wasm (SIMD)	Wasm (SIMD+Threads)	WebGL
MobileNet v2 TFLite	139.54	45.03	24.73	35.74

Wasm (SIMD+Threads) speedups 5.6X than Wasm (Plain) and 1.8X than Wasm (SIMD) .
