Thanks. Yes, I remember Chainer, but only vaguely. I kinda remember looking at it, but not actually using it.

My recollection is that when I looked at Chainer back then, it didn't offer a comprehensive library of preexisting components for deep learning. When I tried PyTorch, on the other hand, I vividly remember it as already having lots of prebuilt components (common layers, activation functions, etc.) in `torch.nn`, so it was easier and faster to get going.

These memories are vague, so I could be wrong.
