Have you solved your problems?

[zhuruihe]

I have figure out the way to solve this problem.
this is the problem related to mmdet/core/evaluation/rmean_ap.py, and sometimes when they try to calculate tp and fp，we will encounter a multiprocess hang problem by "pool.starmap".

        tpfp = pool.starmap(
            rtpfp_default,
            zip(cls_dets, cls_gts, cls_gts_ignore,
                [iou_thr for _ in range(num_imgs)],
                [area_ranges for _ in range(num_imgs)]))
        tp, fp = tuple(zip(*tpfp))

so I just give up using multiprocess, I try to use 'for' loops to replace 'pool.starmap' and problem solved.

        mytp = []
        myfp = []
        for cdt, cgt, cgti, iout, arear in zip(cls_dets, cls_gts, cls_gts_ignore,
                                              [iou_thr for _ in range(num_imgs)],
                                              [area_ranges for _ in range(num_imgs)]):
            tp, fp = rtpfp_default(cdt, cgt, cgti, iout, arear)
            mytp.append(tp)
            myfp.append(fp)
        mytp = tuple(mytp)
        myfp = tuple(myfp)
        tp, fp = mytp, myfp
