copy: boolean indicating whether to deep copy array elements. Default: false. To flatten to a specified depth, set the depth option. var arr = [ 1, [2, [3, [4, [ 5 ], 6], 7], 8], 9 ]; var out = flattenArray( arr, { 'depth': 2 }); // returns [ 1, 2, 3, [4,...

numpy中的reshape函数和squeeze函数是深度学习代码编写中经常使用的函数,需要深入的理解。 其中,reshape函数用于调整数组的轴和维度,而squeeze函数的用法如下, 语法:numpy.squeeze(a,axis = None...numpy中reshape的用法 我们知道在数据输入的时候经常需要对数据的格式进行reshape,下面简单讲一下reshape的用法 上面简单...
However, the simplest way to create an ndarray is using a similar list with the np.array() function. >>> myNdArray = np.array([1, 2, 3]) >>> myNdArray array([1, 2, 3]) >>> type(myNdArray) <class 'numpy.ndarray'> >>> Here, you can see that myNdArray is of the ...
