QLIB的安装踩坑-畏途巉岩不可攀
（写在前面）
使用conda环境来安装，win10
（询问了某相关人，他表示最好使用Linux安装，可能坑少）
conda在这种动不动装错了要回退的地方简直救我狗命
如果有什么相关询问的可以评论，如果我遇到的我会尽力解答
安装Qlib里面遇到的问题
不能安装numpy最新版，这个似乎是老毛病了，我之前装啥的时候遇到过一次，卸载numpy并且安装大概就是降级到numpy1.19.3就可以了，可以继续往下跑了
在报错信息里面可以找到numpy相关的字样
- 主要是这些问题

其实我机子的VS已经差不多好久没装过了，那么就装一个VS吧，谁让他不带运行库呢。
有个人给出了一种解决方法，不知道靠不靠谱
- 不报错了，但是在这里卡好久

mlflow下不下来呗，我的conda配置了豆瓣的镜像，那我手动PIP install就好了
这个mfflow安装好了，他应该是试图安装qlib了，我也不知道为啥，给我提示这些

装第一个的时候就出了点问题，谁知道之后怎么样
我TEMIAO?

matplotlib还需要正好这个版本可还行，我一个一个装不是办法啊
Searching for matplotlib==3.1.3
那么直接PIP装非最新版怎么样呢？
是个办法，但是还是安装CVXPY是一个非常致命的问题，报告同样错误

那么这里是CVX的问题，采取以下链接的办法
https://blog.csdn.net/Teddy_of_mm/article/details/105184531
解决了吗？没有的，安装完之后报错依旧
有人提示使用PIP3？可以吗？
结果仍然是报错依旧。
有人提示使用管理员权限来安装，还是报错依旧
这个error code相关的错误通常是，安装的系统架构版本不太一样，或者版本不太一样之类的
通常不是安装程序内部出了问题
看到这个老哥表示https://blog.csdn.net/wf_he/article/details/108505852
cvxpy目前仅支持3.7.2以下的版本
我火速
conda create -n wr2 python=3.7.2
pip install cvxpy，结果秒成功，
然后先pip install pyqlib
其实，他把我含辛茹苦安装的cvxpy给卸载了，估计是要重新安装，在这里卡了很久，不知道会不会成功
问了一下某大牛，大牛让我换源，推荐在Linux下面安装之类的，但是也表示不应该有这么多报错
至少pip程序是跑下来了，只有一行黄色的warning是关于pip版本太低的
（对，如果你们遇到问题可以考虑装个高一点的python
到此，“稳定版”安装完成
至于开发板的话，使用setup.py运行的那个嘛，因为setup里面指定的下载源太慢了，我觉得只要改善一下众所周知的网络原因就好了
那么开始hello world
