Updates to work with Chainer 5.1.0 and Python 3

[sometimescasey]

The following changes allowed me to run gconv_experiments using:

• chainer (5.1.0)
• cupy-cuda90 (5.1.0)
• Python 3.6.7

Addresses many of the issues mentioned in #13 .

Feel free to close PR if you don't want to merge, but I thought I'd put this here for others who might find it useful. Thanks!

Hi, I use python Python 2.7.15 and I change the code according to this. But one error is thrown out as the following:
AttributeError: 'module' object has no attribute 'Reshape
Is there any way to solve that?

[sometimescasey]

@Ning0Luo unfortunately all my changes above were tested against Python 3.6.7, and I'm not sure what specific versions of the necessary packages you're using. I suspect you just need to upgrade a package. Do you have the full stacktrace, so we can see what specific line threw that error?
