Description:

Installing collected packages: PyYAML
  Running setup.py install for PyYAML ... error
Exception:

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.
