chainer.serializers.save_npz(file, obj, compression=True)[source]

Saves an object to the file in NPZ format.

This is a short-cut function to save only one object into an NPZ file.

  • file (str or file-like) – Target file to write to.

  • obj – Object to be serialized. It must support serialization protocol. If it is a dictionary object, the serialization will be skipped.

  • compression (bool) – If True, compression in the resulting zip file is enabled.
