多数时候，我们都可以利用搜索引擎找到自己需要的东西，但是也不是每次都给力，一是搜索的内容中没有自己需要的内容，二是搜索引擎没收录。就比如说大鱼号作者，好多网友自己申请了个大鱼号，又或者需要查找一个大鱼号，去搜索引擎查找，给人的结果往往不尽人意，那么我们怎么才能搜索查找到大鱼号作者，为啥连大鱼号作者排行榜上的作者都找不到？

带着这个疑问我们就来搜索一次试试。

首行来查看一下今天的大鱼号榜单。找个时尚榜单看看。第一名的是蓓小西，如下图：

 



然后在百度里去搜索“蓓小西”，结果中只有QQ和搜狗号的，百度结果如下：



再在360中去搜索，同样结果，和百度差不多，如下图：



再去搜狗试试，只有微博以及悟空问答，如下图：



再来看看全球最知名的谷歌，也只有今日头条，知乎、搜狗与百家号，没有要的结果，如下：



甚至加入了直搜索大鱼号的关键词也没有结果，如下图：



 

大家都知道，大鱼号是UC与阿里的结合品，那么上神马搜索试试，结果也很遗憾，如下图：



就连神马都无能为力，这个作者的微博、百家号、搜狐号、知乎等号都可以搜索到，唯独大鱼号无法找到，大家还记不记得淘宝，你在搜索引擎上也是找不到它的商品信息，因为淘宝本身启用了robots协议，就是不让搜索引擎收录，这就像国际公约，凡是做搜索引擎的都应该遵守，它的生意不靠搜索引擎，只需要上网者知道“淘宝”两个字就行。至于大鱼号是不是也启用了robots协议，这不得而知，或许。一些知名点的大鱼号作者可以通过神马搜索到，但多数排名都很差，运气好点会在第1页，运气不好，翻好几页都可能找不到，所以直观又快速的方法是这样来找。

快速搜索到大鱼号作者的方法：

打开UC浏览器手机版，向上滑动，上面有个关注，点开。



 

你所关注的都在这里，但这个你肯定没有关注，所以找不到，看到上面有个“+”号，点击，这里是各种分类，推荐的都是一些大神级别号，不一定是我们要找的对象。如图：



 

所以还利用它的搜索功能，最顶上的右边有一个放大镜，点击，输入我们要找的作者，马上就找到，如图：



点开它，就可以看到她写的文章了，这个过程不需要关注就可以实现，如下图：




至此，我们已经将怎么才能搜索查找到大鱼号作者的方法介绍给了大家。

如何能够快速搜索到大鱼号作者的关键点

1.通过神马搜索引擎搜索，但和排名有关，搜索起来麻烦；

2.通过手机UC浏览器能够快速找到，必须有安装该浏览器，至于UC浏览器电脑版没试过，但我觉得还是有手机版方便。

如果你还有什么方法可以快速搜索到大鱼号作者，也请你告诉我，大家一起学习。

编辑：好的，所以我决定尝试一些随机的东西，我有罗斯比也口述作为一个必要的组成部分。我从我的cmakelists文件中删除了所有OpenCV的内容，现在它只显示了与rospy相同的错误，以及与std-msg相同的处理。我第一次开始用ROS在这台电脑上，我正在用ROS教程，一切都很好，直到这一点。。
我知道很多人对此都有麻烦，运行catkin-make/cmake，发现它找不到你的OpenCV文件：Could not find a package configuration file provided by "OpenCV" with any
of the following names:
OpenCVConfig.cmake
opencv-config.cmake
当我尝试使用roscpp、rospy等时也出现了这个错误：Could not find a package configuration file provided by "roscpp" with any
of the following names:
roscppConfig.cmake
roscpp-config.cmake
到目前为止我试过的是：
导出OpenCV_DIR、CMAKE_PREFIX_PATH等。人们在堆栈上建议的大多数内容。仍然会出现这个错误。
检查以确保OpenCV安装正确，使用IDMTEST，我发现一切都是正确的。我可以很好地将opencv与python等一起使用
以及Tsyvarev从评论中得到的解决方案：
如果是简单的find_包(OpenCV)，那么任何一个都应该有帮助：1。cmake-DOpenCV_DIR=/usr/share/OpenCV。。。。2。cmake-DCMAKE_PREFIX_PATH=/usr。三。导出CMAKE_PREFIX_PATH=/usr。
这些.cmake文件位于：
/usr/共享/OpenCV
和
/usr/local/share/OpenCV
不确定他们是否能被定位在其他地方，试着做了一个大规模的搜索，它似乎只是指向这两个特定的文件夹
浏览了我的CMakeLists.txt文件，并按照.cmake文件的指示添加了目录、目标库等
我真的不知道现在该怎么办。

要push内核所有东西到git远程仓库里

找了一圈都找不到Git里怎么add带点的目录（带点的文件夹）
然后用git help add
查看手册
找到这么一行
       -f, --force
           Allow adding otherwise ignored files.
然后就搞定了
使用git add -f *

我想在sympy中使用jacobDN函数,所以我下载它并且
python setup.py成功安装它.
>>> from sympy.mpmath import *
Traceback (most recent call last):
File "", line 1, in 
ImportError: No module named mpmath
>>>
从sympy导入的所有东西都是成功的：
>>> from sympy import *
>>>
然后我单独安装了mpmath,然后我可以使用mpmath的ellipfun.然而,显示了令人讨厌的mpf：
>>> from mpmath import *
>>> ellipfun('dn',0.5,0.5)
mpf('0.94297242577738571')
>>>
问题是如何在sympy.mpmath下使用ellipfun？如何检查我的安装漏洞？
以上解决方案是最好的！如果不能,我怎么能像使用普通函数一样在mpmath中使用ellipfun？
