尝试运行matplotlib显示图片

测试这里的案例

http://matplotlib.org/1.3.1/examples/images_contours_and_fields/image_demo.html

"""
Simple demo of the imshow function.
"""
import matplotlib.pyplot as plt
import matplotlib.cbook as cbook

image_file = cbook.get_sample_data('ada.png')
image = plt.imread(image_file)

plt.imshow(image)
plt.axis('off') # clear x- and y-axes
plt.show()

图片看上去不错
