恐らく後から追加してくださる予定だったと思うのですが,念のため早い内に共有しておきたいのでご確認ください.
論文にまとめる段階で,結果の再現性の確保をお願いします.
計算のパフォーマンスは落ちてしまいますが,よろしくお願いいたします!
def init_seed(seed=1234):
"""
PyTorchの再現性を確保する.
計算の冒頭で呼び出せば良い.
Parameters
----------
seed: integer
ランダムシード値
Returns

また,torch.utils.data.DataLoaderで複数のWorkerを指定する場合も再現性の確保が必要です.
def worker_init_fn(worker_id):
"""
PyTorchのtorch.utils.data.DataLoaderで複数のWorkerを指定する場合に再現性を確保する.
この関数をoption"worker_init_fn"で指定する.

new_seed = np.random.get_state()[1][0] + worker_id
np.random.seed(new_seed)
