python 安装coreml

2、安装pip, 下载get-pip.py, https://bootstrap.pypa.io/get-pip.py，然后Python 这个文件，如果没有权限就加sudo
3、安装coreml：这个各种报error，利用了以下这种使用虚拟环境的方式，不方便的一点就是每次需要在虚拟环境里使用coreml：

You're trying to change your system Python. That's why it says [Errno 1] Operation not permitted. To avoid messing up system libraries, you need to create separate Python virtual environment. This is how to do it:

Upgrade pip:
pip install --upgrade pip
Install virtual environment.
pip install –U virtualenv
Create new virtual environment:
cd ~
virtualenv coreml
This creates folder ~/coreml/ and a local copy of Python, pip and all other stuff you need for work.
To activate virtual environment:
source coreml/bin/activate
Now you see in your terminal (coreml) prepends your user name.
In newly created virtual environment:
pip install -U coremltools
Check that library was installed successfully:
python
import coremltools
There should not be any error messages.
To deactivate virtual environment run:
deactivate

没有权限的话，就在前面加sudo
