我发现了产生这种奇怪行为的原因：在其中一个模块中，我引入了一个错误pd.options.display.float_format = '{:,.0d}'.format，只有在打印DataFrame时才会显示出来。我将把我最初的问题留在这里，这样它可能会帮助其他人。
我正在研究我的代码中的一个错误，现在我发现在代码的一部分(一个模块(中，我可以将csv读取到Panda DataFrame中而没有问题(例如，最后我可以在调试控制台中执行df(，而在另一部分(另一个模块，但当我尝试打印它时，我会得到以下错误：ValueError: Unknown format code 'd' for object of type 'float'(当我在调试控制台中执行df时，我得到<pandas.core.frame.DataFrame object at 0x172dcad60>(。

在两个模块上读取的精确指令是相等的(！(，但我得到了
df = pd.read_csv(results_path / f'{results}.csv')
我无法复制它，除非我通过现有的代码(通过现有的模块(运行它。如果我使用一个新程序，它只是用pd.read_csv()函数读取csv，那么问题就不会发生。我真的无法理解这一点，所以我把这个留在这里，希望有人能发现我做错了什么。
也许问题出在数据上：它似乎同时存在int值和float值。您应该尝试将列转换为浮点类型。(这是read_csv方法中的一个参数(
