还是不行,Traceback (most recent call last): File "C:\Users\star\PycharmProjects\numbers\testcnn.py", line 15, in <module> padded_text = F.pad_sequence([torch.tensor(indexed_text)], batch_first=True) AttributeError: module 'torch.nn.functional' has no attribute 'pad_sequence'

浅谈Python traceback的优雅处理
非常抱歉,我再次给出的示例代码依然有误。在PyTorch中,pad_sequence函数位于torch.nn.utils模块中,而不是torch.nn.functional模块中。请尝试以下修改后的代码:
```python
import torch
import torch.nn as nn
import torch.nn.utils.rnn as rnn_utils
# 假设有一个文本 "I love PyTorch"
text = ["I", "love", "PyTorch"]
# 构建词汇表
vocab = {"<PAD>": 0, "I": 1, "love": 2, "PyTorch": 3}
# 编码文本
indexed_text = [vocab[word] for word in text]
# 序列填充
padded_text = rnn_utils.pad_sequence([torch.tensor(indexed_text)], batch_first=True)
# 嵌入层
embedding = nn.Embedding(num_embeddings=len(vocab), embedding_dim=10)
embedded_text = embedding(padded_text)
# 文本向量化
text_vector = torch.mean(embedded_text, dim=1)
print(text_vector)
```
这次使用了torch.nn.utils.rnn模块的pad_sequence函数,代码应该能够正常运行。非常抱歉给您带来的困扰!如果还有其他问题,请随时提问。
