我在Ubuntu上使用Python 2.7,在开始为我的算法类分配之前,我正在试验图像.我已经下载了numpy,scipy和skimage包,我不断收到"imread"'title'的错误,这些内置函数未定义.知道什么可能是错的吗？

   from pylab import *
   from skimage import img_as_float

   img = imread(‘someimage.png’)
   img = img_as_float(img)
   w, h = img.shape[:2]
   R = img[:,:,0]
   G = img[:,:,1]
   B = img[:,:,2]
   figure()
   gray()
   subplot(1,4,1); imshow(img); title(“RGB”)
   subplot(1,4,2); imshow(R); title(“Red”)
   subplot(1,4,3); imshow(G); title(“Green”)
   subplot(1,4,4); imshow(B); title(“Blue”)
   show()
