壞參數內部函數錯誤蟒蛇

我有一個使用ReportLab的創建報表的Python腳本，該腳本已經過測試，偶爾我收到以下錯誤消息，但預期工作壞參數內部函數錯誤蟒蛇

TraceBack info: 

File "C:\tools\LegionellaTool.py", line 605, in <module> 

createReport(selectedCoolingTowers, Report_outputs_folder, dbo_COLGIS, openPDF) 

Error Info: 

..\Objects\moduleobject.c:50: bad argument to internal function

線605是createReport(selectedCoolingTowers, Report_outputs_folder, dbo_COLGIS, openPDF)

createReport是......創建報告的函數。我已經通過代碼調試，我沒有得到任何錯誤，什麼可能會使錯誤出現，錯誤只發生在場合，而在其他場合，報告創建罰款。

你能提供完整的堆棧跟蹤嗎？還有一些我們可以看看的代碼？ – Paco

@Paco，代碼運行在名爲ArcGIS的外部程序中，它調用腳本，所以我無法獲得完整的堆棧跟蹤。我用創建報告代碼更新了原始問題 - 它有點長... – MapMan

@Paco，完整跟蹤添加到原始問題 – MapMan

在我experi因爲ReportLab的間歇性錯誤通常是由於嘗試渲染可能具有「怪異」內容的文本時引起的問題，例如字符集或空值的意外字符。仔細查看你的代碼，我沒有注意到任何明顯會導致問題的東西，但是你可能想要考慮某些事情包含意外值的可能性。

特別是，我會看看處理selContact的代碼，看看它的任何屬性是否意外爲空或者不是可能導致錯誤的字符串。

沒有完整的堆棧跟蹤，很難說更具體的東西。

ETA

基於現在提供堆棧跟蹤，貌似這個問題必須是有東西進入了title變量，你想被用於繪製字符串畫或字體。看着你的代碼，我沒有注意到任何問題，但沒有任何暗示拋出錯誤的部分代碼的間歇性問題。

我在原始問題中添加了完整的跟蹤。 – MapMan

這個消息讓我抓狂，在過去幾個星期，我終於想通了兩件事情導致此錯誤，以及如何解決這些問題：

爲G湘沃利III建議，如果你嘗試建立您的報告包含錯誤的元素，可能會顯示。

修復：找到哪個元素已損壞或在ArcGIS外部調試程序，您將看到更多明確的錯誤消息。
如果你的Python安裝有點搞砸了，它可能會出現。我發生的是，我將ReportLab文件包含在與腳本相同的文件夾中，以便於分發。但我之前也在我的Python安裝文件夾中安裝了ReportLab。不知怎的，那讓ArcGIS困惑。

修復：刪除Python ?? /（ArcGIS ??/lib/site-packages/reportlab文件夾，以便您的腳本只有一個庫選項。

我希望能幫到別人。
