No module named 'request' (from panda import PandaRequest)
#### Code Sample, a copy-pastable example if possible
```python
# Your code here
import panda as pd
Traceback:
File "/usr/local/lib/python3.4/dist-package/panda/__init__.py", line 1, in <module>
    from request import PandaRequest
```
#### Problem description
I'm working with python 3.4.2, gcc 4.9.1

I have installed everything with pip, all the requirement is good. All the version is good and up to date (my pip3.4 and setuptools, is up to date too).
I've installed Panda and Pandas. (the same)
I've tried to install request, requests (already had)

Don't really know, what to do now :)

#### Expected Output
I can't enter inside the module itself. I can't event know the version.
#### Output of ``pd.show_versions()``

Thanks to help me
