已经安装了gensim后,使用from gensim.models.wrappers.dtmmodel import DtmModel 报错No module named 'gensim.models.wrappers'
很抱歉,我在上面给出的代码中犯了一个错误。gensim的DTM模型不再位于`gensim.models.wrappers`模块中,而是位于`gensim.models.dtmmodel`模块中。请尝试使用以下代码:
```python
from gensim.models import DtmModel
from gensim.corpora import Dictionary
# 读取文档数据
documents = [
"This is the first document",
"This document is the second document",
"And this is the third one",
"Is this the first document?"
]
# 创建词典
dictionary = Dictionary([doc.lower().split() for doc in documents])
# 创建语料库
corpus = [dictionary.doc2bow(doc.lower().split()) for doc in documents]
# 指定DTM的路径
dtm_path = '/path/to/dtm/binary'
# 指定DTM的参数
dtm_params = {
'model': dtm_path,
'corpus': corpus,
'id2word': dictionary,
'num_topics': 3, # 设定主题数量
'time_slices': [1, 1, 1, 1], # 设定时间切片,这里假设每个文档都属于一个时间切片
}
# 创建DTM模型
dtm_model = DtmModel(**dtm_params)
# 获取文档的主题分布
doc_topics = dtm_model.get_document_topics(corpus)
# 打印每个文档的主题分布
for i, doc in enumerate(doc_topics):
print(f"Document {i+1}: {doc}")
```
请确保将`/path/to/dtm/binary`替换为实际的DTM二进制文件路径。如果仍然遇到问题,请确保已正确安装gensim库,并尝试更新到最新版本。如果问题仍然存在,请尝试重新安装gensim。
非常抱歉给你带来了困扰,希望这次能够解决问题。如果还有其他问题,请随时提问。
帮助我针对以下代码画一个类图from django.db import models from django.db.models import Sum from django.contrib.auth.models import User from introduction.models import ScenicSpot # Create your models here. class OrderStatus(models.TextChoices): NOT_PAID = ('r', "ready to pay") PAID = ('p', "paid") class Order(models.Model): name = models.CharField(max_length=50) status = models.CharField(max_length=30, choices=OrderStatus.choices) purchase_time = models.DateField(auto_now_add=True) user = models.ForeignKey(User, related_name="orders", on_delete=models.CASCADE) def caculate_total_price(self): total_price = self.tickets.aggregate(total=Sum('scenic_spot__ticket_price')).get('total') return total_price class Ticket(models.Model): name = models.CharField(max_length=200) order = models.ForeignKey(Order, related_name="tickets", on_delete=models.CASCADE) scenic_spot = models.ForeignKey(ScenicSpot, related_name="tickets", on_delete=models.CASCADE)
根据给出的代码,可以画出以下类图:
```
+------------------+ +------------------+
| OrderStatus | | Order |
+------------------+ +------------------+
| - NOT_PAID: str | | - name: str |
| - PAID: str | | - status: str |
+------------------+ | - purchase_time: |
| date |
| - user: User |
+------------------+
| - calculate_total_price()|
+------------------+
|
|
+------------------+
| Ticket |
+------------------+
| - name: str |
| - order: Order |
| - scenic_spot: |
| ScenicSpot |
+------------------+
```
注意:这只是一个示例类图,可能还有其他的类和关系未在代码中给出。
