Я пытаюсь получить образец heatmap.py от: http://jjguy.com/heatmap/"IOError: декодер зип не доступен": Ubuntu Python PIL
#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")
и я получаю эту ошибку:
Processing 400 points...
Traceback (most recent call last):
File "/home/ec2usr/workspace/image/image.py", line 14, in <module>

Отработка Eclipse на Ubuntu 12 (64-битной) системе с Python 2.7.
Я нахожу libz.so в обоих/usr/lib и/usr/lib/x86_64-linux-gnu/просто отлично. Я пробовал эти решения уже без результата:
PIL says it has "support available" but still gives IOError when saving files

Я потянув меня за волосы над этим в течение нескольких дней и значительно цените чью-либо помощь!

Вы имели 'libz.so' там при установке PIL? – wRAR
Я так считаю, но я также повторно нарисовал яйцо PIL с sudo apt-get build-dep python-imaging впоследствии, на всякий случай. – cmacdona101
обновление: .tif работает нормально; png и jpg не работают. – cmacdona101
