### Install `langroid`
Langroid requires Python 3.11+. We recommend using a virtual environment.
Use `pip` to install a bare-bones slim version of `langroid` (from PyPi) to your virtual 
environment:
```bash
pip install langroid
```
The core Langroid package lets you use OpenAI Embeddings models via their API. 
If you instead want to use the `sentence-transformers` embedding models from HuggingFace, 
install Langroid like this: 
```bash
pip install "langroid[hf-embeddings]"
```
For many practical scenarios, you may need additional optional dependencies:
- To use various document-parsers, install langroid with the `doc-chat` extra:
    ```bash
    pip install "langroid[doc-chat]"
    ```
- For "chat with databases", use the `db` extra:
    ```bash
    pip install "langroid[db]"
    ```
- You can specify multiple extras by separating them with commas, e.g.:
    ```bash
    pip install "langroid[doc-chat,db]"
    ```
- To simply install _all_ optional dependencies, use the `all` extra (but note that this will result in longer load/startup times and a larger install size):
    ```bash
    pip install "langroid[all]"
    ```

<summary><b>Optional Installs for using SQL Chat with a PostgreSQL DB </b></summary>

If you are using `SQLChatAgent` 
(e.g. the script [`examples/data-qa/sql-chat/sql_chat.py`](https://github.com/langroid/langroid/blob/main/examples/data-qa/sql-chat/sql_chat.py)),
with a postgres db, you will need to:

- Install PostgreSQL dev libraries for your platform, e.g.
  - `sudo apt-get install libpq-dev` on Ubuntu,
  - `brew install postgresql` on Mac, etc.
- Install langroid with the postgres extra, e.g. `pip install langroid[postgres]`
  or `poetry add "langroid[postgres]"` or `poetry install -E postgres`,
  (or the corresponding `uv` versions, e.g. `uv add "langroid[postgres]"`
  or `uv pip install langroid[postgres]`).
  If this gives you an error, try `pip install psycopg2-binary` in your virtualenv.
</details>

📝 If you get strange errors involving `mysqlclient`, try doing `pip uninstall mysqlclient` followed by `pip install mysqlclient`.
