所以我正在编写一个界面，它将自动执行一些步骤数据分析。该代码涉及将用于不同功能的多个屏幕。我写的第一个是EDA(探索性数据分析)屏幕。该代码有效，但会生成报告，然后关闭 Tk 窗口。
具体来说，当我生成报告时，代码会生成报告然后关闭。我没有把代码生成放在那里，因为它不使用 Tkinter。还忽略了其他屏幕，因为它们没有问题，而且我不想将整个项目转储在这里。

最佳答案
在最初生成部分报告后，我确实遇到了一些问题，但是 Tk就我而言，窗口没有关闭。
该错误与您的 HTMLCreator 中的以下几行有关文件:
if(len(X_all.columns.values)>50):
advert_report = sv.analyze(X_all,pairwise_analysis="off",target_feat=col)
else:
print("here")
advert_report = sv.analyze(X_all,pairwise_analysis="on",target_feat=col)
Sweetviz根据文档，目前仅支持 BOOLEAN 和 NUMERICAL 功能作为目标:target_feat: A string representing the name of the feature to be marked as "target". Only BOOLEAN and NUMERICAL features can be targets for now.
因此，通过运行如下代码，错误不会出现:
if(len(X_all.columns.values)>50):
advert_report = sv.analyze(X_all,pairwise_analysis="off")
else:
print("here")
advert_report = sv.analyze(X_all,pairwise_analysis="on")
target仍然奇怪地抛出错误，但您可以使用 FeatureConfig object 作为强制数字列目标的变通方法，如果列不是数字类型，您仍然会收到错误。feature_config = sv.FeatureConfig(force_num=col)
if(len(X_all.columns.values)>50):
advert_report = sv.analyze(X_all, pairwise_analysis="off", feat_cfg=feature_config, target_feat=col)
else:
print("here")
advert_report = sv.analyze(X_all, pairwise_analysis="on", feat_cfg=feature_config, target_feat=col)
