Numpy基础(一) 一、数组的创建numpy.array()创建一个序列型数组对象numpy.zeros()创建一个元素全为0的数组对象numpy.ones()创建一个元素全为1的数组对象numpy.arange创建等间隔的一维数组numpy.linspace创建均匀分布的一维数组numpy.full创建由固定值填充的数组 数组 一维数组 序列型 Numpy基础(二) Numpy索引 数组...
Huge amounts of memory used when running a loop that creates or loads a numpy array, slices the array, and saves to a list. Reproducing code example: I found this issue while making a loop that Ioads a sound at each iteration and slices the first seconds. I managed to reproduce the ...
