Python imageio and visvis draws lines

Question

I'm new to python My problem is that imageio and visvis draws vertical lines instead of pixel, what's wrong?

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)

Maybe you could explain what you were hoping to draw? – Mark Setchell Jun 28 '20 at 14:15 — Mark Setchell, Jun 28 '20 at 14:15

I've managed it by replacing imout=[[[255,255,255]]*len(imin[0])]*len(imin) with imout=np.zeros((len(imin),len(imin[0]),3))
