Question

特别是在opennmt-py中。现在，有关此主题的问题很多，例如Getting alignment/attention during translation in OpenNMT-py和opennmt论坛https://github.com/OpenNMT/OpenNMT-py/issues/575上的以下主题。我使用后者建议的代码。但是似乎没有一个解决我的问题。我尝试运行以下简单的代码段。

import onmt
import onmt.inputters
import onmt.translate
import onmt.model_builder
from collections import namedtuple


Opt = namedtuple('Opt', ['models', 'data_type', 'reuse_copy_attn', "gpu"])


opt = Opt("/home/Desktop/hidden-att/model/hidden-2/seed-0/LSTMlang1_step_400.pt", "text",False, 0)
fields, model, model_opt =  onmt.model_builder.load_test_model(opt,{"reuse_copy_attn":False})

我得到了此错误跟踪。

Traceback (most recent call last):

    raise type(e)(msg)

AttributeError: 'dict' object has no attribute 'seek'. You can only torch.load from a file that is seekable. Please pre-load the data into a buffer like io.BytesIO and try to load from it instead.

那么有人遇到并解决了这个问题吗？还是知道去哪里看？我想这与已加载文件有关，但是它是用opennmt-py以相当标准的方式进行训练的。

您可以在翻译脚本中添加--attn_debug参数以查看注意力权重。

translate.py ... \
             -attn_debug \
             ...

在opennmt-py中获得关注权重
