[TonyLi-Shu]

Hi I encounter a problem with this after setting up the environment.
I wonder if you can offer an suggestion. Thank you in advance.

CuPy (cupy) version 6.0.0 may not be compatible with this version of Chainer.
Please consider installing the supported version by running:
$ pip install 'cupy>=6.3.0,<7.0.0'

See the following page for more details:
