python - AttributeError：“矩形”对象没有属性“左”

Question

我有以下代码：

import numpy
import skimage.io, skimage.color
import matplotlib.pyplot

raspberry = skimage.io.imread(fname="E:\Sem 5\Seminar\ANN\Rasb.jpg", as_gray=False)
apple = skimage.io.imread(fname="E:\Sem 5\Seminar\ANN\App.jpg", as_gray=False)
mango = skimage.io.imread(fname="E:\Sem 5\Seminar\ANN\man.jpg", as_gray=False)
lemon = skimage.io.imread(fname="E:\Sem 5\Seminar\ANN\lemon.jpg", as_gray=False)

apple_hsv = skimage.color.rgb2hsv(rgb=apple)
mango_hsv = skimage.color.rgb2hsv(rgb=mango)
raspberry_hsv = skimage.color.rgb2hsv(rgb=raspberry)
lemon_hsv = skimage.color.rgb2hsv(rgb=lemon)

fruits = ["apple", "raspberry", "mango", "lemon"]
hsv_fruits_data = [apple_hsv, raspberry_hsv, mango_hsv, lemon_hsv]
idx = 0
for hsv_fruit_data in hsv_fruits_data:
    fruit = fruits[idx]
    hist = numpy.histogram(a=hsv_fruit_data[:, :, 0], bins=360)
    matplotlib.pyplot.bar(200, height=hist[0], left=numpy.arange(360))
    matplotlib.pyplot.savefig(fruit+"-hue-histogram.jpg", bbox_inches="tight")
    matplotlib.pyplot.close("all")
    idx = idx + 1

我收到以下错误：

Traceback (most recent call last):
  File "e:\Sem 5\Seminar\ANN\ann_algo.py", line 21, in <module>

    raise AttributeError(f"{type(self).__name__!r} object "
AttributeError: 'Rectangle' object has no property 'left'

我该如何解决？
