上記の外部ライブラリをインストールしてPDF生成しようとすると

Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22) [MSC v.1500 32 bit (Intel)] on win32
Type "copyright", "credits" or "license()" for more information.

from reportlab.pdfgen import canvas

Traceback (most recent call last):
File "<pyshell#0>", line 1, in <module>
from reportlab.pdfgen import canvas
ImportError: No module named reportlab.pdfgen

となります。
ダウンロードインストールは
https://bitbucket.org/rptlab/reportlab
こちらから巡って
ReportLabの-3.3.0-CP27-なし-win32.whl （MD5）
フォルダNameは

お世話になります。上記で確認しましたがWindowsではやはりうまくいきません。PipをUpgradeしなさいと出てUpgradeするとエラーになります。なぜなのかわかりません

You are using pip version 8.1.1, however version 8.1.2 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.
