Sto cercando di ottenere il heatmap.py campione che va da: http://jjguy.com/heatmap/"IOError: decoder zip non disponibile": 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")
e ottengo questo errore:
Processing 400 points...
Traceback (most recent call last):
File "/home/ec2usr/workspace/image/image.py", line 14, in <module>
img.save("classic.png")
File "/usr/local/lib/python2.7/dist-packages/PIL/Image.py", line 1437, in save

IOError: encoder zip not available
Utilizzo di Eclipse su un sistema Ubuntu 12 (64 bit), con Python 2.7.
trovo libz.so sia in/usr/lib e/usr/lib/x86_64-linux-gnu/bene. Ho provato queste soluzioni già senza risultato:
PIL says it has "support available" but still gives IOError when saving files

Sono stato tirando fuori i miei capelli su questo per un paio di giorni e notevolmente apprezzare l'aiuto di nessuno!

Hai avuto 'libz.so' lì quando è stato installato PIL? – wRAR
Credo di sì, ma ho anche reintallato PIL egg con sudo apt-get python-imaging build-dep in seguito, per ogni evenienza. Aggiornamento – cmacdona101
: .tif funziona bene; png e jpg non funzionano. – cmacdona101
