AttributeError出现在Pyevolove中

Question

最近我来到pyevolve，我已经非常感谢这个模块了。

但是我得到了一个我不能理解的错误。

这是一种如下情况：

Traceback (most recent call last):
File "C:\Users\*****\Documents\workspace\*****\src\sales.py", line 99, in <module>
ga.evolve(freq_stats=100)
File "C:\Python27\lib\site-packages\pyevolve\GSimpleGA.py", line 754, in evolve
self.initialize()
File "C:\Python27\lib\site-packages\pyevolve\GSimpleGA.py", line 593, in initialize
self.internalPop.initialize(ga_engine=self)
File "C:\Python27\lib\site-packages\pyevolve\GPopulation.py", line 353, in initialize
gen.initialize(**args)
File "C:\Python27\lib\site-packages\pyevolve\GenomeBase.py", line 147, in initialize
for it in self.initializator.applyFunctions(self, **args):
File "C:\Python27\lib\site-packages\pyevolve\FunctionSlot.py", line 180, in applyFunctions
yield f(obj, **args)
File "C:\Users\*****\Documents\workspace\*****\src\sales.py", line 61, in G1DListTSPInitializator
lst = [i for i in xrange(genome.listSize)]
AttributeError: G1DList instance has no attribute 'listSize'

如何解决此错误？

Answer 1

这就是错误所说的意思。

G1DList没有listSize属性，必须使用.getListSize()方法。
