在Celery进口 rembg
原标题:Importing rembg in Celery Task breaks workers
I m trying to use the rembg library in a Celery worker (Django), but once I import the library, the worker is exited prematurely: objc[47160]: +[NSCharacterSet initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug. [2024-07-24 14:16:14,501: ERROR/MainProcess] Process ForkPoolWorker-16 pid:47160 exited with signal 6 (SIGABRT) [2024-07-24 14:16:14,514: ERROR/MainProcess] Message: Error: { signal : , sender : <@task: assets.tasks.image_background.remove of oml at 0x1046a5c50>, task_id : 6219ab75-62b5-4d14-88ac-034d9fa71d45 , exception : WorkerLostError( Worker exited prematurely: signal 6 (SIGABRT) Job: 15. ), args : [], kwargs : {}, traceback : Traceback (most recent call last): File "/Users/cesarrodriguez/.pyenv/versions/3.11.2/lib/python3.11/site-packages/billiard/pool.py", line 1264, in mark_as_worker_lost raise WorkerLostError( billiard.exceptions.WorkerLostError: Worker exited prematurely: signal 6 (SIGABRT) Job: 15. , einfo : } Data: {} [2024-07-24 14:16:14,514: ERROR/MainProcess] Task handler raised error: WorkerLostError( Worker exited prematurely: signal 6 (SIGABRT) Job: 15. ) Traceback (most recent call last): File "/Users/cesarrodriguez/.pyenv/versions/3.11.2/lib/python3.11/site-packages/billiard/pool.py", line 1264, in mark_as_worker_lost I m not sure if it s something related to multiprocessing Issues, have any thoughts?

It looks like the the error is not python related but a Mac M1 error instead. After solving the log error: [__NSCFConstantString initialize] may have been in progress in another thread when fork() was called Thanks to this issue So, in summary, execute this command in your current bash session: export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
