Problem running pip install -r requirements.txt on Windows

[louisgv]

I'm on Windows and I'm trying to pip install -r requirements.txt, my python and pip version are:

PS D:\Project\Github\otc-unity\obstacle-tower-challenge> python
Python 3.7.2 (tags/v3.7.2:9a3ffc0492, Dec 23 2018, 23:09:28) [MSC v.1916 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

PS D:\Project\Github\otc-unity\obstacle-tower-challenge> pip --version
pip 19.0.2 from c:\users\lgvic\appdata\local\programs\python\python37\lib\site-packages\pip (python 3.7)

When I tried to install dependency, here's the error:

PS D:\Project\Github\otc-unity\obstacle-tower-challenge> pip install -r requirements.txt

I have looked around but couldn't find a solution for this. Thanks in advance for any help :smile:

Found the solution. It was Python 3.7, i.e it's doesn't have the package. Downgrade to 3.6 worked! First time doing python stuff on Windows XD
