全局变量Agree是在所有函数外部定义的命名元组:

Agree = collections.namedtuple('Agree', ['kappa', 'alpha','avg_ao'], verbose=True)


从该函数返回指定的元组:

def getagreement(task):
    return Agree(kappa=task.kappa(),alpha=task.alpha(),avg_ao=task.avg_Ao())


在这里叫腌制:

     future_dict[executor.submit(getagreement,task)]=frozenset(annotators)
       ...
       detaildata[future_dict[future]]=future.result()

 cPickle.dump(detaildata,open(os.path.dirname(jsonflist[0])+'\\out.picl','w'))


拆开会产生错误:

c=cPickle.load(open(subsdir))
Traceback (most recent call last):
  File "<interactive input>", line 1, in <module>
  AttributeError: 'module' object has no attribute 'Agree'


反汇编文件:

 pickletools.dis(f)
  126: c    GLOBAL     '__builtin__ tuple'
  147: p    PUT        9
  151: (    MARK

  196: F        FLOAT      0.7004133685136325
  218: t        TUPLE      (MARK at 151)

  File "C:\Python27\Lib\pickletools.py", line 2009, in dis
    raise ValueError(errormsg)
ValueError: no MARK exists on stack


泡菜和cPickle都给出类似的错误。

最佳答案

我猜您是在一个模块中定义了Agree,然后尝试在未定义Agree的另一个模块中加载数据。尝试以下类似方法,如果可行,将已定义的命名元组导入加载数据的模块中。

import collections
import cPickle
Agree = collections.namedtuple('Agree', ['kappa', 'alpha','avg_ao'], verbose=True)
c = cPickle.load(open(subsdir))
