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)

Answer 1

我通过用 imout=np.zeros((len(imin),len(imin[0]),3))

替换 imout=[[[255,255,255]]*len(imin[0])]*len(imin) 来管理它
