Some python packages have version conflicts

[Ryan]

I found requirements.txt and requirements-gpu.txt out of date, which some packages cant download, and not support Python 3.8.

I change some lines, do like this:

conda create -n advbox python=3.7
git clone https://github.com/baidu/AdvBox.git
pip install -r requirements.txt -i https://mirror.baidu.com/pypi/simple

requirements.txt and requirements-gpu.txt should be like this:
