Could not import asyncio library in virtualenv.

>>>import asyncio
Traceback (most recent call last):
File "C:\Python36\Lib\asyncio\__init__.py", line 16, in <module>

ImportError: cannot import name '_overlapped'

import _overlapped # Will also be exported.
OSError: [WinError 0] The operation completed successfully
There is no module _overlapped in asyncio folder "C:\Python36\Lib\asyncio\". Also I know that asyncio is a part of Python from version 3.4.
What is wrong and what should i do? Could it be due to x64 Win and not x64 Python?

I'm trying to install Flask inside Wine so that I can package with cx_freeze. I've had it working for a while, but I've just added Flask to the project.
However, I can't seem to import Flask due to a missing library required by the core asyncio library. The cause of this is an import that is only included in windows systems called _overlapped. The code can be seen here.
I can confirm that there is a library contained within the dlls folder:
root#375a857194f3:/src# find /root/.wine -iname *overlapped*
/root/.wine/drive_c/Python36/DLLs/_overlapped.pyd
An example import and error message can be found below.

When I run a code which imports spynner, I get the following error:

A funny thing is that I can import those things in normal python shell without any problem:

Okay I figured it out. The problem is that spynner first tries to import PySide, and it gets an error in importing QSslConfiguration from PyQt4.QtNetwork. And then it switches to PyQt4, and apparently the previously imported PySide makes the PyQt4 import fail. When I remove the try: part in browser.py I could import spynner fine.
I want to install paramiko on win 7 32bit ,the python is 3.3 .
I can compile it，but get follow errors:

Paramiko does not run on Python 3. Yet. I'm working on a development branch (https://github.com/dorianpula/paramiko/tree/python3-support) to add support for Python 3, and I'm working on fixing this particular issue.
I have followed the installation directions to install the GHMM library. However, I still get the following error:

ImportError: libghmm.so.1: cannot open shared object file: No such file or directory
I tried to change my LD_PRELOAD_PATH variable to /usr/local/lib to no avail.
Also, when I try to locate libghmm, I get the following, so the libraries are definitely there:
% locate libghmm
/usr/local/lib/libghmm.a
/usr/local/lib/libghmm.la
/usr/local/lib/libghmm.so
/usr/local/lib/libghmm.so.1
/usr/local/lib/libghmm.so.1.0.0
Any ideas?
