使用list.remove时出现Python值错误

Question

我使用pandas读取电子表格，然后使用迭代将其拆分，以及其他一些操作。但是，当我尝试对其中一个结果数据帧使用list.remove（）方法时（即使在将其转换为列表之后），它会抛出以下内容：

ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all() 

以下是完整的代码：

def correlationTester2(startSample, minSample):
    df = list(pd.read_csv('C:/Users/iijof/Desktop/sheet.csv').values)
    df = random.sample(df, len(df))
    dfTry = []
    dfTest = []
    counter = {}
    for i in df:
        if counter.get(i[9], 0) < startSample:
            dfTry.append(i)
            counter[i[9]] = counter.get(i[9], 0) + 1
        else:
            dfTest.append(i)
            counter[i[9]] = counter.get(i[9], 0) + 1

    tryCopy = list(dfTry)
    testCopy = list(dfTest)        
    for i in counter.keys():
        if counter[i] < minSample:
            for name in tryCopy:
                if name[9] == i:
                    dfTry.remove(name)
            for name in testCopy:
                if name[9] == i:
                    dfTest.remove(name)

    return dfTry, dfTest, counter

dfTry, dfTest, counter = correlationTester2(50,100)

运行dfTry.remove（name）行时出错。我怎么修理它

如果我需要提供有关电子表格结构的信息，请告诉我，谢谢
