Soliloquy

In the article here, I mentioned Chainer 2.0, which is ** coming soon **, but which is released first, Chainer 1.22? Will it be ...

I'm looking forward to both.

Postscript

The one who was developing was Tweeted

Chainer v1.21.0 is a modest improvement, especially concatenate is 15 times faster and split is about 2 times faster in the test at hand, and some bottlenecks of NLP tasks are eliminated.

Ah, there is overhead for Chainer (Variable generation cost), so is cupy alone faster?

I want to benchmark.
