AttributeError: load (替身packet.py)

Question

我环顾四周，却找不到任何关于这件事的东西。这个问题可能是因为我对Python有点陌生，我希望能在这里得到一些帮助。

我看到了2009年的一篇博文：http://stacksmash.org/2009/09/packet-visualization-with-python/

然而，当我运行它时，我会在Scapy的packet.py的第1129行中得到以下错误

$ python test-image.py 
Traceback (most recent call last):
  File "test-image.py", line 9, in <module>
    if(len(pkt.load) > imgWidth):
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
    192, in __getattr__
  fld,v = self.getfield_and_val(attr)
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
  189, in getfield_and_val
  return self.payload.getfield_and_val(attr)
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
  189, in getfield_and_val
  return self.payload.getfield_and_val(attr)
  File "/usr/local/lib/python2.7/dist-packages/scapy/packet.py", line 
  1125, in getfield_and_val
  raise AttributeError(attr)
AttributeError: load

这可能是更新的库版本的问题(考虑到这是2009年的博客)还是我在这里遗漏了什么？

这对我适用于Python 3.6.4

from PIL import Image
from scapy.all import rdpcap

capture = rdpcap('./capture.pcap')
imgHeight = len(capture)

imgWidth = max(len(packet) for packet in capture)

imgSize = imgWidth, imgHeight
print('Image Size: ', imgSize)

img = Image.new('RGB', imgSize, (255, 255, 255))

for i in range(0, imgHeight):
    for j in range(0, len(capture[i])):
        color = ord(str(capture[i])[j])
        # print('Writing pixel', (j,i), 'with value:', color)
        img.im.putpixel((j,i), (0, color, 0))

img.save('./result.png')
