Description:

Installing collected packages: PyYAML
  Running setup.py install for PyYAML ... error
Exception:
Traceback (most recent call last):
  File "c:\users\nathan\appdata\local\programs\python\python36-32\lib\site-packages\pip\compat\__init__.py", line 73, in console_to_str
    return s.decode(sys.__stdout__.encoding)

During handling of the above exception, another exception occurred:

What I've run:

git clone https://github.com/ritiek/spotify-downloader
cd .\spotify-downloader
pip3 install -U -r requirements.txt

Edit: Fixed: I just executed in windows cmd: chcp 65001 and CodePage changed to UTF-8.

Virtual Environment Setting
Python version: 3.6.3
Operating system: Windows, 64 Bits

Keras was not installing because of pyyaml setting not meeting up for python 3.6.
I already had Anaconda installed in a different virtualenv with keras working fine (pyyaml module installed). I just used conda install pyyaml instead of pip and it got installed, thereby using pip install keras to install the keras library in my new virtual environment.
