mindspore.load

mindspore.load(file_name, **kwargs)

Load MindIR.

The returned object can be executed by a GraphCell, see class mindspore.nn.GraphCell for more details.

Parameters

• file_name (str) – MindIR file name.

• kwargs (dict) –

  Configuration options dictionary.

  • dec_key (bytes): Byte type key used for decryption. The valid length is 16, 24, or 32.

  • dec_mode (str): Specifies the decryption mode, to take effect when dec_key is set. Option: ‘AES-GCM’ | ‘AES-CBC’. Default: ‘AES-GCM’.

Returns

Object, a compiled graph that can executed by GraphCell.

Raises

• ValueError – MindIR file name is incorrect.

• RuntimeError – Failed to parse MindIR file.

Examples

>>> import numpy as np
>>> import mindspore.nn as nn
>>> from mindspore import Tensor, export, load
>>>
>>> net = nn.Conv2d(1, 1, kernel_size=3, weight_init="ones")
>>> input_tensor = Tensor(np.ones([1, 1, 3, 3]).astype(np.float32))
>>> export(net, input_tensor, file_name="net", file_format="MINDIR")
>>> graph = load("net.mindir")
>>> net = nn.GraphCell(graph)
>>> output = net(input_tensor)
>>> print(output)
