我得到了:

IOError: decoder zip not available

当我尝试绘制图像并保存到PIL中的jpeg时.有关如何解决此问题的任何想法？在查看/上传图片时,PIL过去一直很适合我.

我试图从得到样品heatmap.py运行: http://jjguy.com/heatmap/

#image.py
import heatmap
import random

if __name__ == "__main__":    
    pts = []
    for x in range(400):
        pts.append((random.random(), random.random() ))

    print "Processing %d points..." % len(pts)

    hm = heatmap.Heatmap()
    img = hm.heatmap(pts)
    img.save("classic.png")

我收到此错误:

Processing 400 points...
