### Reproduction
https://github.com/langchain-ai/langchain/pull/14266 added a deprecation for `input_variables` argument of `PromptTemplate.from_file`. It was released in 0.0.346.
However, https://github.com/langchain-ai/langchain/blob/v0.0.346/libs/langchain/langchain/chains/llm_summarization_checker/base.py#L20-L31 still uses `input_variables` at the module-level. So now this `DeprecationWarning` is emitted simply for importing from LangChain.
Can we fix this, so LangChain isn't emitting `DeprecationWarning`s?

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

### Reproduction
1. The setup is the same as in https://github.com/langchain-ai/langchain/issues/14231, although I don't think it matters.
2. Run `existing_graph.similarity_search_with_score("It is the end of the world. Take shelter!")`
3. It returns the following error

To use, you should have the ``pgvector`` python package installed.
Args:
connection_string: Postgres connection string.
embedding_function: Any embedding function implementing
`langchain.embeddings.base.Embeddings` interface.
collection_name: The name of the collection to use. (default: langchain)
NOTE: This is not the name of the table, but the name of the collection.
The tables will be created when initializing the store (if not exists)
So, make sure the user has the right permissions to create tables.
distance_strategy: The distance strategy to use. (default: COSINE)
pre_delete_collection: If True, will delete the collection if it exists.
(default: False). Useful for testing.
engine_args: SQLAlchemy's create engine arguments.
