np.empty() 函数语法如下: empty(shape[, dtype, order]) 依给定的shape, 和数据类型 dtype, 返回一个一维或者多维数组,数组的元素不为空,为随机产生的数据
if method 1 is used it creates a raw binary array on disk without the description header that np.save creates, were as method 2 first creates an empty array then saves it to disk and finally reloads it as a writable memmap'ed file, this is inefficient. ...
If you use both thehighand thelowparameter in your syntax, the output array will contain random integers within the range[low, high). That means that np.random.randint will draw integers from the range starting atlow, up to but excludinghigh. However, if youdo notuse thehighparameter, then...
