python如何显示数组np.set_printoptions方法的相关属性:

set_printoptions(precision=None, threshold=None, edgeitems=None, linewidth=None, suppress=None, nanstr=None, 
infstr=None)

对于每个属性的释义:

precision : int, optional,float输出的精度,即小数点后维数,默认8( Number of digits of precision for floating point output (default 8))

threshold : int, optional,当数组数目过大时,设置显示几个数字,其余用省略号(Total number of array elements which trigger summarization rather than full repr (default 1000))

edgeitems : int, optional,边缘数目(Number of array items in summary at beginning and end of each dimension (default 3))

linewidth : int, optional,The number of characters per line for the purpose of inserting line breaks (default 75)

suppress : bool, optional,是否压缩由计数法表示的浮点数(Whether or not suppress printing of small floating point values using scientific notation (default False))

nanstr : str, optional,String representation of floating point not-a-number (default nan)

infstr : str, optional,String representation of floating point infinity (default inf)

实例: 

np.set_printoptions(threshold='nan') (意思是全部打印)
