    "Passing negative integer to header is invalid. "
ValueError: Passing negative integer to header is invalid. For no header, use header=None instead

报错命令：

pd.read_csv("a.txt",header=-1,sep="\s+")

报错原因：
pandas升级了，不支持"header=-1"这种写法了，改为了：“header=None”

解决方法：

pd.read_csv("a.txt",header=None,sep="\s+")
