Numpy torch 変換 copy
Web25 nov. 2024 · If the tensor is on gpu or cuda, copy the tensor to cpu and convert it to numpy array using: tensor.data.cpu ().numpy () If the tensor is on cpu already you can do tensor.data.numpy (). However, you can also do tensor.data.cpu ().numpy (). If the tensor is already on cpu, then the .cpu () operation will have no effect. Webって思うだろうけど、単純にタイピング量が多いのでできるだけ使いたくはない。そんで、そもそも初期値の設定に対してnumpyからの変換とか全然使わない。実はこのcopyの呼び出しが起こるのは、numpyからの変換の時に特異的に起こるものなのだ。
