def writePic(picnum,picres):

  return vv.imwrite('\picsout\pic'+str(picnum)+'.png',np.array(np.uint8(picres)))

def dothisandthat(pnum):

 global rewards,reward

 pictime=time.time()

 tphase=pnum>4

 imin=readPic(pnum)

 imout=[[[255,255,255]]*len(imin[0])]*len(imin)

 for i in range(len(imin)):

    for j in range(len(imin[i])):

        obsP=obsPixels(i,j,imin)

        if tphase:

            train()

            fcol=find_col(obsP,pnum)

        else:

            fcol=random_trainer()

        imout[i][j]=fcol

        reward=calcRew(i,j,imin,fcol)

        rewards.append(reward)

        obs1,obs2,obs3,obs4,obs5=obsP

        remember_recdata([*fcol,*obs1,*obs2,*obs3,*obs4,*obs5,pnum])

        if True:

            writePic(pnum,imout)

我已经通过替换来管理imout=[[[255,255,255]]*len(imin[0])]*len(imin)它imout=np.zeros((len(imin),len(imin[0]),3))
