gym

当在Window环境下使用Gym模块的时候，基础环境都能使用，但是使用Atari游戏模型会报错 OSError: [WinError 126] 找不到指定的模块。 该问题出在Window10版本的Gym模块只做到了部分支持，要想解决该问题，应执行以下步骤： 1.先卸载掉之前安装的gym 　　pip uninstall atari -py 　　pip uninstall gym [atari ] 2.下载 VS build tools https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools&rel=16 3运行 VS build tools并安装以下工具 4.重启电脑 5.安装cmake, atari-py 和 gym 　　pip install cmake 　　pip install atari -py 　　pip install gym [atari ] 6.测试 　　 import atari_py 　　 print (atari_py .list_games ( ) ) 转载： https://blog.csdn.net/weixin_44210881/article/details/103031995 来源： https://www.cnblogs.com

BUPT2017 wintertraining(15) #4 A - I.Cubes Gym - 101164I 题意 将n拆成最少个立方数相加的形式。 题解 根据n的范围，立方数最大不超过400的立方，并且个数也不会很多。 dfs，设置一个深度的上限up。从大到小枚举立方数，剪枝条件：当前层数加上至少还需要的层数>=up就return。 代码 #include <cstdio> #include <cstring> using namespace std; int n,c[500],a[101],ans[1001],up=50; void dfs(int d,int x,int k){ if(x==0){ up=d; for(int i=1;i<=d;i++)ans[i]=a[i]; } if(d+1>=up||d+x/c[k]>=up)return; for(int i=k;i;i--)if(c[i]<=x){ a[d+1]=i; dfs(d+1,x-c[i],i); } } int main() { for(int i=1;i<=400;i++)c[i]=i*i*i; scanf("%d",&n); dfs(0,n,400); printf("%d\n",up); for(int i=1;i<=up;i++)printf("%d ",ans[i]); return 0; }

1.安装gym也要在虚拟环境下进行安装，对于虚拟环境的建立，使用conda，可以参考博客 https://blog.csdn.net/qs17809259715/article/details/103729478 方法一： 1.第一次尝试： 前提要先进入虚拟环境，然后使用如下命令 sudo apt-get install -y python-numpy python-dev cmake zlib1g-dev libjpeg-dev xvfb libav-tools xorg-dev python-opengl libboost-all-dev libsdl2-dev swig git clone https://github.com/openai/gym.git pip install -e .[all] 报错 ERROR: File “setup.py” not found. Directory cannot be installed in editable mode: /home/qxw 突然发现再使用–user的时候，因为新开终端，而没有进入gym路径，导致出错。 在cd 切换到gym路径后，运行pip install --user -e ‘.[all]’，问题解决。 最终命令： sudo apt-get install -y python-numpy python-dev

[Gym - 101064F Metal detector] 递推 题目链接 ： [Gym - 101064F Metal detector] 题意描述 ：有N个人排队，第一个人出队，第二个人调到队尾，第三个人出队，第四个人调到队尾，……依次类推，求第K个人是第几个出队的。 1 ≤ N ≤ 10 9 //--> 解题思路 ：今天组队赛的时候SB了，推了好久，没有搞出来。卡在这么个水题上。 当K是奇数的时候， 毫无疑问，答案就是 K 2 + 1 //--> ; 考虑K为偶数的情况： N为偶数：ans(N, K)==>N/2 + ans(N/2, K/2); N为奇数：ans(N, K)==>N/2 + ans(N/2+1, K/2+1); 为什么是这样的呢？是因为本次操作先将N/2个元素出队，然后多余了最后一个元素先不处理，就相当于最后一个元素放在下一次操作里面去，那么下一次操作就相当于要处理N/2+1个数，其他的数字向后移动一位。这个感觉可意会不好言传… #include <bits/stdc++.h> using namespace std ; #define FIN freopen("input.txt","r",stdin) #define FOUT freopen("output.txt","w",stdout) int N, K; int solve ( int n,
