Gracefull python joblib kill

问题

Is it possible to gracefully kill a joblib process (threading backend), and still return the so far computed results ?

parallel = Parallel(n_jobs=4, backend="threading")
result = parallel(delayed(dummy_f)(x) for x in range(100))

For the moment I came up with two solutions

• parallel._aborted = True which waits for the started jobs to finish (in my case it can be very long)
• parallel._terminate_backend() which hangs if jobs are still in the pipe (parallel._jobs not empty)

Is there a way to workaround the lib to do this ?
