ValueError: cannot convert float NaN to integer 无法将浮点NaN转换为整数 1. 2. 3. 查看一下Nan的类型: import numpy as np print(type(np.nan)) 1. 2. 显示结果: <class 'float'> 1. np.nan是一个float类型,查资料发现,nan无法强制转换为int类型 错误解决方法 原本以为直接判断就很轻松可以解决,代...

skip_footer: int, default 0 不推荐使用:建议使用skipfooter ,功能一样。 nrows: int, default None 需要读取的行数(从文件头开始算起)。 na_values: scalar, str, list-like, or dict, default None 一组用于替换NA/NaN的值。如果传参,需要制定特定列的空值。默认为‘1.#IND’, ‘1.#QNAN’, ‘N/...
