You probably installed the wrong package. (pip install discord or discord-rewrite)
The correct command is:

pip install -U git+https://github.com/Rapptz/discord.py@rewrite

or with voice send support:

pip install -U git+https://github.com/Rapptz/discord.py@rewrite#egg=discord.py[voice]

obligatory text excerpt:

For further help specific to using this library, you should join either the official discord.py server or the Discord API server, as the README recommends.

Duplicate of #1280.
This should be fixed in the latest version of the rewrite branch.
