TypeError:调用用于生成嵌入的Bert方法时，Int'对象不可调用

Question

我有下面的代码，我得到了“TypeError:“tuple”对象是不可调用的（在新的时间），但我不明白为什么。我是根据这个教程写的 https://jalammar.github.io/a-visual-guide-to-using-bert-for-the-first-time/和 https://github.com/getalp/Flaubert

我的代码：

#torch == 1.8.1
#numpy == 1.20.2
#pandas == 1.0.3
#transformers == 4.6.1


from transformers import logging
logging.set_verbosity_warning()

import numpy as np
import torch
from transformers import FlaubertModel, FlaubertTokenizer

language_model_dir = 'flaubert/flaubert_small_cased' # version > 2.0.0
flaubert, info = FlaubertModel.from_pretrained(language_model_dir, output_loading_info=True)
flaubert_tokenizer = FlaubertTokenizer.from_pretrained(language_model_dir)

# f_verbatim is a " <class 'pandas.core.series.Series'>", table of sentences
tokenized = f_verbatim.apply((lambda x: flaubert_tokenizer.encode(x, add_special_tokens=True, max_length=512, padding=True, truncation=True))) 
#print(tokenized)

#Padding
max_len = 0
for i in tokenized.values:
    if len(i) > max_len:
        max_len = len(i)
padded = np.array([i + [0] * (max_len - len(i)) for i in tokenized.values])
# set data to tensor format
input_ids = torch.tensor(padded)
print(type(input_ids)) #<class 'torch.Tensor'>

attention_mask = np.where(padded != 0, 1, 0)
print(type(attention_mask))  #<class 'numpy.ndarray'>

# this line is causing the error
hidden_state = flaubert(input_ids, attention_mask=attention_mask)

据我所知，这个问题是由于缺少一个逗号造成的，但我无法解决。 打印“福楼拜”功能提供：

Answer 1

这是因为from_pretrained函数提供了模型和字典的元组，而您没有将它们分开。按如下方式修改代码（添加另一个变量）：

flaubert, info = FlaubertModel.from_pretrained(language_model_dir, output_loading_info=True)

您已将output_loading_info设置为True。所以它还返回一个字典。如果不指定赋值变量，它将向flaubert变量传递一个元组（模型、字典）。因为falubert是一个元组，所以不能执行它

更新：attention_mask是一个numpy数组，但您的模型需要一个torch张量。因此，在将其传递给模型之前，将其转换为火炬张量

attention_mask = torch.from_numpy(attention_mask)
hidden_state = flaubert(input_ids, attention_mask=attention_mask)
