np.set_printoptions函数

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

  

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,线条宽度 The number of characters per line for the purpose of inserting line breaks (default 75).

suppress :

   bool, optional,是否压缩由科学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).
