tfjs 3.4.0 regression: wasm causes browser hang
See original GitHub issuetfjs 3.4.0 was just released and unfortunately wasm module is somewhat broken
to be precise, tfjs-backend-wasm.wasm and tfjs-backend-wasm-simd.wasm seem to work (although haven’t tested in depth)
what’s definitely broken is tfjs-backend-wasm-threaded-simd.wasm
and symptoms are simple - complete browser hang,
up to a point where browser window is nonresponsive to close requests and requires a hard kill
to reproduce:
- enable
WebAssembly SIMD supportin chrome://flags - enable
WebAssembly threads supportin chrome://flags - set backend to
wasm - run any model inference
this used to work in all recent versions of tfjs
environment: tfjs 3.4.0 on windows 10 with chrome 89 or edge 89

Hi @vladmandic , we are releasing 3.5.0 with this fix today.
@mattsoulanille thanks!
given it’s a regression that causes hangs, does this warrant spinning up a tfjs service build (e.g., 3.4.1)? (cc @pyu10055)
