RSS订阅原创 pytorch0.4.0版本如何加载torch0.4.1模型，看这里
0.4.1训练的模型会有 num_batches_tracked结尾的参数，事实上这些参数记录的信息 一般情况模型并不需要。0.4.0加载模型的时候 不会识别num_batches_tracked结尾的名字故需要将0.4.1的模型参数中num_batches_tracked结尾的参数删除例如价值0.4.1模型得到一个state_dictstate_dict = torch.load(mod...

转载 苏格拉底与那个失恋的孩子
**苏格拉底：孩子，你为什么悲伤？ 失恋者：我失恋了。 苏格拉底：哦，这很正常啊。如果失恋没有悲伤，恋爱大概也就没有什么味道。可是，年轻人，我怎么发现你对失恋头的投入比恋爱的投入还要倾心呢？ 失恋者：到手的葡萄给丢了，这份遗憾，这份失落，您非当事人，怎知其中的酸楚啊。 苏格拉底：丢了就丢了，和不继续向前走呢，鲜美的葡萄有很多。 失恋者：等待，等到海枯石烂，知道她回心转意向我走来。 苏格拉

原创 数据结构-树状数组讲解
树状数组的作用：树状数组是对一个数组改变某个元素和求和比较实用的数据结构。其中”求和，更改“两部操做的时间复杂度都是O(log(n))，n为数组元素个数。在解题过程中，我们有时需要维护一个数组的前缀和S[i]=A[1]+A[2]+...+A[i]。但是不难发现，如果我们修改了任意一个A[i],S[i]、S[i+1]...S[n]都会发生变化。可以说，每次修改A[i]后，调整前缀和S[]在最坏情况下

原创 快速幂
以前头脑里面根本没有快速幂的概念，今天算接触了快速幂;快速幂用来求m的n次方的，当 n很大时比如说n=1000000000，那么普通的O(n)求法会超时的（也不一定看出题人给的事件限制）。但有种做法是运用快速幂。可以把时间复杂度降到O（logn）。比如，我想求2^21那么 我可以通过求2，2^4,2^16求得。把21 分成1 4 16 。原理：以下以求a的b次方来介绍把b转换成二进制数。该二进制数
