Will it support Python 3.x? about deep-crf

[tianjianjiang]

Chainer v2.1.0 source code says it won't work with Python 3.5.0, so I guess the latest working Python 3.x would be 3.4.8.

I think you can use Python 3.x.
Which code causes problems in v3?

Actually I don't use Python 3.x.
Could you tell me your opinion?

@tianjianjiang I confirmed that Chainer v.2.1.0 and v1.24.0 source codes say it won't work with Python 3.5.0.

Accoding to the manual, Chainer supports Python 2.7.6+, 3.4.3+, 3.5.1+, 3.6.0+.

See

• https://docs.chainer.org/en/v1.24.0/install.html
• https://docs.chainer.org/en/v2.1.0/install.html
• chainer/chainer#4304

I've tested with 3.5.2 and 3.6.3, seems working, but with one caveat: for unknown reason (I didn't investigate further), pip(3.5|3.6) chainer==2.1.0 didn't check the compatible version of cupy, which should be 1.0.3. The pip of 3.4.8 and 2.7.12, however, verified this dependency correctly.
