I used anaconda to create a virtual envs.
Anaconda location: /usr/local/anaconda
My envs location: ~/.conda/envs/py2713

Then I activated my environment, did pip upgrade using: sudo pip install
--upgrade pip
Collecting pip
  Downloading pip-9.0.1-py2.py3-none-any.whl (1.3MB)
Installing collected packages: pip
  Found existing installation: pip 9.0.0
    Uninstalling pip-9.0.0:
      Successfully uninstalled pip-9.0.0
Successfully installed pip-9.0.1

But when I do "pip -V", it still using 8.1.1 as follows:
pip 8.1.1 from /usr/local/anaconda/lib/python2.7/site-packages (python 2.7)

when I do "which -a pip", it shows:

But whichever I use, it all triggered the 8.8.1 version from

Just started anaconda, and any help is appreciated.
