wasm_cc_binary with tensorflow lite minimal example failed about emsdk HOT 7 OPEN

The error message is complaining about atomics, so maybe it needs to be built with threads. Try adding threads = "emscripten", to your wasm_cc_binary

Thank you very much. Build completed successfully now

I am using WebAssembly (Wasm) in a WeChat Mini Program environment, but it does not support Web Workers.

worker=new Worker(pthreadMainJs,workerOptions)

Would you like additional information or suggestions on how to handle WebAssembly in WeChat Mini Programs without Web Workers? @walkingeyerobot

like without option threads = "emscripten" in wasm_cc_binary,

thank you so much !~

Are you able to get tensorflow lite to compile without threads outside of bazel and run in your environment? If yes, I'm happy to help dig into this further. If no, I think that's a question for hte tensorflow lite folks.

Thank you very much for your help.

According to the advice from a TensorFlow Lite team member, I tried remove the -pthread lines in the emlink params file and ran emcc_link.sh. It was successful, although the generated wasm-loader.js is larger than usual. Are there any unfinished tasks that need to be completed after running emcc_link.sh?

This works internally in google3 (you can ping me in chat for a link) for building @tensorflow/tfjs-tflite, so I think the Bazel wasm tooling probably supports it. My guess is there's something misconfigured in the oss build, possibly before anything gets passed to wasm_cc_binary, that's causing it to use threads even when threads are not requested. If that's the case, then this is a TFLite issue.

I found a solution to fix the emcc_link issue by threads = "off" and adding -s USE_PTHREADS=0
