I am in windows 10 env, using python 2.7.8 32 bit version. When I try to install matplotlib thru whl file as

pip install matplotlib-2.0.0-cp27-cp27m-win32.whl

I obtained the error
.......
File "c:\python27\lib\zipfile.py", line 811, in _RealGetContents
raise BadZipfile, "File is not a zip file"
BadZipfile: File is not a zip file

The same error comes when I try to other versions of matplotlib*whl file ( matplotlib-2.0.0-cp34-cp34m-win32.whl, matplotlib-2.0.0-cp35-cp35m-win32.whl).

Any help in resolving the issue is appreciated.
