升级gluoncv到0.8版（用conda install解决找不到chardet的问题）

用pip install 和 conda install 到底有什么不同，很多时候真难以说清楚，非常明确的是，安装 的位置“有时”确实不同。这次gluoncv升级就碰到了。

(1) 卸载旧的gluoncv

pip uninstall gluoncv

(2) 然后在这里把最新的gluoncv下载下来，

[https://github.com/dmlc/gluon-cv][https_github.com_dmlc_gluon-cv]

解压后切换到目录下用`python setup.py install`命令进行安装（我的mxnet-cu101安装 在mx36gpu环境）

(mx36gpu) D:\mXNet\gluon-cv-master>python setup.py install

安装到最后，Processing dependencies时居然报错了，

gluoncv 0.8.0 is already the active version in easy-install.pth
    
    Installed d:\anaconda3\envs\mx36gpu\lib\site-packages\gluoncv-0.8.0-py3.6.egg
    Processing dependencies for gluoncv==0.8.0
    error: [Errno 2] No such file or directory: 'd:\\anaconda3\\envs\\mx36gpu\\lib\\site-packages\\chardet-3.0.4.dist-info\\METADATA'

（3）用conda install 安装 chardet

然后我用`pip install chardet`时，却被告知已经被安装上了

(mx36gpu) D:\mXNet\gluon-cv-master>pip install chardet
    Requirement already satisfied: chardet in c:\users\administrator\appdata\roaming\python\python36\site-packages (3.0.4)

回想起以前安装不少文件包时，一般都会使用 anaconda这个channel，比如

conda install -c anaconda \<pakage-name>

所以我尝试这样安装

(mx36gpu) D:\mXNet\gluon-cv-master>conda install -c anaconda chardet

    Solving environment: done

(4) 最后重新setup一下gluoncv，成功。大致看了下，检查了很多包的依赖关系。
