ChainerのLinkのパラメータ数を求める

Posted at

Link.params() を使う．

>>> import chainer.links as L
>>> model = L.Linear(3, 4)
>>> model.W.data.size
12
>>> model.b.data.size
4
>>> sum(p.data.size for p in model.params())
16

chainer.Chain でもいける．

>>> import chainer
>>> model = chainer.Chain(a=L.Linear(3, 4), b=L.Linear(2, 3))
>>> sum(p.data.size for p in model.params())
25
