Question

因此，对于一个项目，我正在查询一堆Google Analytics数据并将其存储到Sqlit3数据库中。现在我正在编写一个脚本，用于检索几个月内每天的历史数据。脚本运行大约一个月没有错误，然后抛出这个奇怪的错误，我找不到很多信息。任何人都可以帮我弄清楚它为什么扔这个。这是某种内存错误吗？

这里是追溯：

    print "Date Range: " + str(date.fromordinal(i))
    p = Populate(str(date.fromordinal(i)), str(date.fromordinal(i)))
#inside populate 
self.fill(ecommerce, EcommerceData())

self.fill(self.query.get_data(qsf.getPageTrackingMetrics(), 
          qsf.getPageTrackingDimensions()), 
          PageTrackingData())

self.fill(self.query.get_data(qsf.getTrafficSourceMetrics(), 
                              qsf.getTrafficSourceDimensions()),
                              TrafficData())

self.fill(self.query.get_data(qsf.getAdwordsMetrics(), 
                              qsf.getAdwordsDimensions()), AdwordsData())

def fill(self, data, object):
    """

    Iterate through the row data, create and append each object to the list

    rows = []
    for row in data:

    for element in rows:

        #print element
        element.save()

好吧所以它似乎是某种与内存相关的错误。如果您收到此错误，则可能通过ram运行了太多变量。简而言之，您需要使您的代码更有效地处理您正在处理的数据，或者将数据切分为更易于管理的数据块。
