完美解决 scipy.misc.imread 报错 TypeError: Image data cannot be converted to float

File "/home/harrison/anaconda3/lib/python3.7/site-packages/matplotlib/image.py", line 634, in set_data
raise TypeError("Image data cannot be converted to float")
TypeError: Image data cannot be converted to float

代码如下：

#!/usr/bin/python
# -*- coding: utf-8 -*-
# auth:  harrison time: 15/07/19

import numpy as np
import scipy.misc as sm
import matplotlib.pyplot as mp

original = sm.imread('../da_data/lily.jpg', True)
#提取特征值
eigvals, eigvecs = np.linalg.eig(original)
eigvals[50:] = 0
print(np.diag(eigvals).shape)
original2 = np.mat(eigvecs) * np.mat(np.diag(eigvals)) * np.mat(eigvecs).I
mp.figure("Lily Features")
mp.subplot(121)
mp.xticks([])
mp.yticks([])
mp.imshow(original, cmap='gray')

mp.subplot(122)
mp.xticks([])
mp.yticks([])
mp.imshow(original2, cmap='gray')

mp.tight_layout()
mp.show()

解决发案：
　　是因为  original  返回值是复数  包含实数，虚数，  只要在取出实数就ok
　　

　　mp.imshow(original.real, cmap='gray')

　　mp.imshow(original2.real, cmap='gray')
