今天CloudIDE打开代码 任务无法完成先是提示未开通CloudIDE点了开通后提示实例不存在有人解答一下吗

第一步：点击免费创建第二步：创建IDE实例，将相应位置信息填好第三步：完成，回到会员中心，刷新页面

昨天有人问怎么提交代码，做完了就忘了，反正是照着手册做的。今天再翻，天，手册也找不到了那就先做个简单的，用CloudIDE打开代码，直接点击任务，就会弹出提示：这是昨天按照手册新建的仓库，额，直接新建就好了，就是一个hello world。建好了，就是这个样子的，注意下右手侧操作栏理的黄色小帽子，是CloudIDE的标志，点击就直接在CloudIDE环境打开你的项目。这样用CloudIDE打开代码的任务就完成了。下面继续，在代码托管的项目右手侧的三个点那点击右键，新建文件，这里增加的是一个md文件。增加完后，执行代码检查，然后分支合并。昨天做的的是从slave新增一个文件，然后合并到master中。这些都做完了，发现，代码提交的任务已经完成了。暂时先解锁这么多吧。部署和发布需要主机组，先放下。

比如在这里，按住CTL，点get_file，没有反应的。我想看看get_file的定义

问题：把x86运行正常的代码放到鲲鹏架构CloudIDE中，遇到了char类型无法正确输入输出的问题。x86运行正常的代码在二楼！！！代码要实现的功能：编写一程序，从键盘上输入任意两个数和一运算符（+：加，-：减，*：乘，/:除），采用switch语句，注意当运算符为除（“/”）时，需要判断除数不能为0，程序会报错，条件全部满足后，计算其运算的结果并输出。在鲲鹏架构的CloudIDE中已经进行的相关操作：源代码直接放到CloudIDE上，无char类型输入过程，直接结束程序。根据官方手册:https://support.huaweicloud.com/pinsrcase-kunpengprocs/kunpengprocessor_18_0004.html中“x86架构下为signed char，在Arm64平台为unsigned char”，把正常代码中的char类型全部替换为unsigned char，并把输入输出用的格式控制字符改从%c改为了%u，运算符能输入，但是输出错误。怎么修改才能让程序的结果和x86平台的结果一致。求指点。在鲲鹏架构的CloudIDE中运行代码如下。#include <stdio.h> int main()  {     float a, b;  //存放两个数的变量     int tag = 0; //运算合法的标志，0--合法，1--非法     unsigned char ch;     //运算符变量,已经替换为鲲鹏架构下unsigned char     float result;//运算结果变量     //这里写输入部分     printf("input two number:");     scanf("%f %f", &a, &b);     fflush(stdin);     printf("input arithmetic lable(+ - */):");     scanf("%u",&ch);         switch(ch)     {         case('+'):result=a+b;break;         case('-'):result=a-b;break;         case('*'):result=a*b;break;         case('/'):             if(!b)             {                 printf("divisor is zero!\n");                 tag=1;//运算非法标志提示             }             else                 result=a/b;             break;         default: printf ("illegal arithmetic lable\n");//非法运算符提示             tag=1;     }     if(!tag)     //这里写输出部分     printf("%.2f %u %.2f=%.2f", a, ch, b, result);     return 0; }结果如下所示，无法得到正常结果。源代码在x86平台运行结果如下，运行正常。

准备工作：申请一个OBS资源，创建一个桶。开启一个CloudIDE实例，打开一个terminal，先下载并安装obs的工具obsutil。配置obsutil:需要用到开发者的我的凭证->访问密钥->新建访问密钥的AK，SK。使用obsutil命令在桶中新建一个文件夹test

实际体验的好处是可以这碰碰，那撞撞，盲人摸象般探测边界在哪儿~昨天看了【操作指南系列】CloudIDE实例中导入Git代码库，今天才try了一下！有了夜读成才的教程，超级顺利~连许久不用的github密码居然一次就蒙对了~23333在github上改了下代码，嗯，没有自动同步到cloudIDE中。再重新import一下，文件夹重名，提示错误。改个文件名，第二次拉取下来。在Cloud IDE修改代码，然后上送git,一直报错鉴权失败，是啊，没有保存github的用户名和密码，这就需要用SSH方式连接github了。密码复制的问题：昨天确实发现代码粘贴不出来，是上面编辑框的代码粘贴不到本地，但是terminal中的文本一直是可以粘贴到剪辑板再到本地的。这里的密码不用使用手册上说的xclip -sel clip < ~/.ssh/id_rsa.pub直接能复制出来就可以了。感觉CloudIDE有点像vmware虚拟机的使用，但VM虚拟机安装了插件后，是可以在虚机和本端自由复制的。

CloudIDE真的是很方便的工具，特别是对需要用到云资源，OBS,RCS等等，的情况下。开发环境，就是生产环境，省去了很多的联通调测问题。但是，对需要外设的场景怎么进行系统的联调的呢？比如银行的应用程序，可能涉及到收银机，虽然能部分用二维码代替，还是需要考虑诸如pos终端机，数字键盘，声音图像设备系统联调。还有Android、Iphone手机APP开发的测试问题。模拟器当然可以跑，但是应用还是需要真机测试这一环节，而且测试的工作量还相当可观，模拟器只能完成基本功能测试，而要用到地理位置信息，无线信号覆盖信息的手机APP开发肯定要结合现场，进行测试的过程。“未来软件吞噬一切！”那么，云IDE未来会成为唯一的开发环境么?还是仅仅如高速公路之于交通呢？

上午试了下，增加多版本的python,换了个网络，安装包下载下来了，安装不了，提示有些文件夹没有权限修改。晚上想跑个程序，用到turtle库，安装不了。搜了下，问题提示的大概率是由于python版本2.7与3.7的语言写法区别，带括号与不带括号。试图修改这个文件的时候，未能修改成功。现在对terminal的文件结构还有点懵。求大神帮渡个劫~

CloudIDE hint功能非常好用，先选代码段关联提示。但是每次新建实例都需要安装，建议直接预置在系统环境中。

手册上提到可以点击左下角任务条更换python版本，试了下，发现只有3.7.0的。尝试命令行窗口下载2.7的python安装包，官网的很慢啊~请问有没有别的源可以用？
