The docker image tagged with Pytorch 1.5 and Python 3.8, has Pytorch 1.4 installed and is running Python 3.7
🐛 Bug
The docker image tagged with Pytorch 1.5, eg 0.8.0rc1-py3.8-torch1.5, has torch 1.4 installed in it, as seen via pip list. Also, it is running Python 3.7 instead of Python 3.8, as the tag indicates.
To Reproduce
Steps to reproduce the behavior:

Pull docker image: docker pull pytorchlightning/pytorch_lightning:0.8.0rc1-py3.8-torch1.5
Run the container: docker run --rm -it --init pytorchlightning/pytorch_lightning:0.8.0rc1-py3.8-torch1.5
Check version of python and pytorch:

containeruser@c5c87a61b71c:~$ python --version
Python 3.7.7

containeruser@71d3c9f95de7:~$ pip list | grep torch
pytorch-lightning         0.8.0rc1           
torch                     1.4.0
Expected behavior
Since the tag of the docker image is 0.8.0rc1-py3.8-torch1.5, I expect to see it running Python 3.8 and Pytorch 1.5.
