This error message usually means that there is no variable or object named "instance_vec" in the current scope. It could be because the variable was not defined or initialized before it was used, or it could be a typo in the variable name. To resolve this error, you need to check your code and make sure that the variable "instance_vec" is defined and assigned a value before it is used.

NameError: name 'corpus_vec' is not defined
这个错误通常是因为在代码中使用了未定义的变量名corpus_vec。这可能是因为变量名拼写错误、变量未被初始化或者变量作用域不正确等原因导致的。为了解决这个问题,你可以尝试以下几种方法:
1.检查变量名是否正确拼写,确保变量名与之前定义的变量名一致。
2.检查变量是否已经被正确地初始化,如果没有,需要先对变量进行初始化。
3.检查变量的作用域是否正确,如果变量定义在函数内部,需要确保在函数外部也能够访问到该变量。
下面是一个例子,展示了如何定义一个变量并对其进行初始化,以避免出现NameError错误:
```python
corpus_vec = []
for doc in corpus_tfidf:
vec = []
for id, value in doc:
vec.append(value)
corpus_vec.append(vec)
print(corpus_vec)
```
