我正在尝试将证据转换的权重应用于我的数据。我正在尝试使用sc.woebin命令对数据进行装箱，但是，此错误不断出现：“序列项0：预期的str实例，找到了int”错误。我不知道我可能做错了什么？
我不知道为什么它不起作用。我尝试了另一台服务器，将其切换了一点，但是我不知道问题出在什么地方，错误在我的情况下到底意味着什么。
bins = sc.woebin(train, y = 'BAD',
min_perc_fine_bin=0.02,
min_perc_coarse_bin=0.05,
stop_limit=0.1,
max_num_bin=8,
method='tree')
预期结果应该只是处理数据而已。但是，以下是实际结果。 “”“
