1.Installation
Recommended
Simply download this directory either directly from GitHub, or using command line:
在teminal中运行：
$ git clone https://github.com/laszukdawid/PyEMD
2.Then go into the downloaded project and run from command line:
在cmd中运行：
$ python setup.py install
3.PyPi
Packaged obtained from PyPi is/will be slightly behind this project, so some features might not be the same. However, it seems to be the easiest/nicest way of installing any Python packages, so why not this one?
在teminal中运行：
$ pip install EMD-signal
4.pychram打开sample，运行测试是否安装成功。
