python - Python PIL.Image 模块似乎与 tkinter 模块冲突（AttributeError: type object 'Image' has no attribute 'open'）

Question

谁能帮我理解为什么我得到“AttributeError：类型对象'Image'没有属性'open'”这个代码。在我看来它真的很干净。奇怪的是，我还尝试在从函数 clicked() 读取时访问全局 var，但这没有用（我现在评论了这些行，但代码中报告了错误）。这可能是一个线索！然而，我迷路了！

非常感谢你的帮助！

    im = Image.open('image.jpg')
    im = im.resize((150, 150))      # optional, to reduce time
    ar = np.asarray(im)
    shape = ar.shape
    ar = ar.reshape(scipy.product(shape[:2]), shape[2]).astype(float)

    print('finding clusters')
    codes, dist = scipy.cluster.vq.kmeans(ar, NUM_CLUSTERS)
    print('cluster centres:\n', codes)

    vecs, dist = scipy.cluster.vq.vq(ar, codes)         # assign codes
    counts, bins = scipy.histogram(vecs, len(codes))    # count occurrences

    index_max = scipy.argmax(counts)                    # find most frequent
    peak = codes[index_max]
    colour = binascii.hexlify(bytearray(int(c) for c in peak)).decode('ascii')
    print('most frequent is %s (#%s)' % (peak, colour))

    lbl.configure(text='most frequent is &peak &colour ')

    return

btn = Button(window, text="Click Me to load image.jpg", command=clicked)
