Installing NLTK using WHL file -

I have previously used WHL (wheel) files to install various Python packages. But, it seems there's no such file for NLTK. Any workaround for this please?

https://pypi.org/project/nltk/

The problem is I don't have access to install or *.exe files. Neither PIP3 works because of some reason (firewall i believe!)

Error:

NewConnectionError('pip._vendor.requests.packages.urllib3.connection.VerifiedHTTPSConnection object: Failed to establish a new connection: [WinError 10061] No connection could be made because the target machine actively refused it',)': /simple/nltk/

Update-1

Just discovered, there was a Zip installation file. And tried it. Had a dependency on "singledispatch-3.4.0.3-py2.py3-none-any.whl" but was able to install that being a WHL file. Got a success message -

Update-2

Still i wasn't able to do Import NLTK. But i noticed an Egg file in the Python folder.

C:\Users\rbpython -m easy_install "C:\Users\rb\AppData\Local\Programs\Python\Python36\Lib\site-packages\nltk-3.4-py3.6.egg"

Still i'm unable to proceed. But the hunt is still on ...
