Webnumpy.argmax. #. Returns the indices of the maximum values along an axis. Input array. By default, the index is into the flattened array, otherwise along the specified axis. If provided, the result will be inserted into this array. It should be of the appropriate shape and dtype. If this is set to True, the axes which are reduced are left in ... WebSep 14, 2024 · 这里用到了两个函数,np.argmax和np.bincount,第一个很常见,就是返回数组中最大值对应的下标,np.bincount可以通过上面的例子理解:首先找到数组最大值max,然后返回0~max的各个数字出现的次数,在上例中,0出现了1次,1出现了1次,2出现了2次...以此类推。
