Python 如何在我的github自述文件上设置pyversions图标？

我正在尝试将我的pyversion图标设置为我的github自述，如下所示：

我一直在尝试从服务器对设置进行反向工程

我的.travis.yaml文件如下所示：

language: python
python:
  - "2.7"
  - "3.3"
  - "3.4"
  - "3.5"
  - "3.6"
install: 
  - pip install tox-travis
  - pip install python-coveralls

script:
  - tox
  - coverage run --source ibm_analytics_engine -m ibm_analytics_engine.iae
  - coverage report -m

after_success:
  - coveralls

我的自述文件有：

[![Pyversions](https://img.shields.io/pypi/pyversions/ibm-analytics-engine-python.svg?style=flat-square)](https://pypi.python.org/pypi/ibm-analytics-engine-python)

但是，我的输出如下所示：

language: python
python:
  - "2.7"
  - "3.3"
  - "3.4"
  - "3.5"
  - "3.6"
install: 
  - pip install tox-travis
  - pip install python-coveralls

script:
  - tox
  - coverage run --source ibm_analytics_engine -m ibm_analytics_engine.iae
  - coverage report -m

after_success:
  - coveralls

pyversions信息从何处获取？是pypi页面上的吗？如果不是，如何让shields.io反映我的库支持的python版本？

好的，python版本是从PyPi读取的

我只需要将此添加到我的setup.py-trove分类器中：

Programming Language :: Python
Programming Language :: Python :: 2.6
Programming Language :: Python :: 2.7
Programming Language :: Python :: 3.3
Programming Language :: Python :: 3.4
Programming Language :: Python :: 3.5
