python imageio和visvis画线

Question

我是 python 新手 我的问题是 imageio 和 visvis 绘制垂直线而不是像素，怎么了？1def 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))
