np.set_printoptions方法的相關(guān)屬性:

set_printoptions(precision=None, threshold=None, edgeitems=None, linewidth=None, suppress=None, nanstr=None, infstr=None)
對于每個屬性的釋義:
precision : int, optional,float輸出的精度,即小數(shù)點后維數(shù),默認8( Number of digits of precision for floating point output (default 8))

threshold : int, optional,當數(shù)組數(shù)目過大時,設(shè)置顯示幾個數(shù)字,其余用省略號(Total number of array elements which trigger summarization rather than full repr (default 1000))
edgeitems : int, optional,邊緣數(shù)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,是否壓縮由科學(xué)計數(shù)法表示的浮點數(shù)(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)
實例:
np.set_printoptions(threshold='nan') (意思是全部打?。?/p>
