在对 dataframe 数据框中某列进行时间戳转换，或其他变换时，出现 ValueError: cannot convert float NaN to integer 这是因为这列中存在空值，无法转换，所以首先找出空值所在的行，然后将其删除；即可。
通常是 Python 整数或浮点数的字符串形式; 也可以是 ‘NaN’(非数字)、表示正负无穷大的字符串(“Infinity” 或“inf”)。字母大小写随意; 字符串前后可以有空白字符。 如果实参是整数或浮点数,则返回具有相同值(在 Python 浮点精度范围内)的浮点数。如果实参在 Python 浮点精度范围外,则会触发OverflowError。
