If python is installed in your system, then pip comes in handy.
So simple steps are:
1) Install virtualenv using

 > pip install virtualenv 
2)Now in which ever directory you are, this line below will create a virtualenv there

 > virtualenv myenv

And here also you can name it anything.

3) Now if you are same directory then type,

 > myenv\Scripts\activate

You can explicitly specify your path too.

If pip is not in your system

1)$ sudo apt-get install python-pip

Then install virtualenv

2)$ pip install virtualenv
Now check your installation

3)$ virtualenv --version
Create a virtual environment now,

4)$ virtualenv virtualenv_name
After this command, a folder named virtualenv_name will be created. You can name anything to it. If you want to create a virtualenv for specific python version, type

5)$ virtualenv -p /usr/bin/python3 virtualenv_name

6)$ source virtualenv_name/bin/activate
Now you are in a Python virtual environment

>pip install -r requirements.txt

>python audio_video_tansfer.py <ip_address_of_other_system>

>ipconfig
