Fail to install cupy with Anaconda

[nhc.bkp...@gmail.com]

 Hi,

I can install chainer but can not install cupy using anaconda (python, pip).

I've also checked this.

Python 3.6.2 |Anaconda, Inc.| (default, Sep 30 2017, 18:42:57)
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import chainer
>>> chainer.cuda.available
False
>>>

 
Here is the error message when installing cupy.

Many thanks.

Hi

This does not really fix the problem but if you are not dependent on Python 3.6.2 and just want to install cupy, a workaround is to switch to an older version such as 3.6.1.

Vincent
