Issue: Error while creating synthetic dataset
Root cause: Environment Incompatibility

Hi @dosu, while using this line of code
from langchain_community.document_loaders import DirectoryLoader 
loader = DirectoryLoader('C:\\Users\\kepa')
documents = loader.load()

It says directory not found error, now everytime I take care of one dependency for example first it stated unable to import libmagic, a new one arises, can you help me? The same code worked for me 4 months ago

<!-- Answer -->
To resolve the "directory not found" error and dependency issues when using `DirectoryLoader` from `langchain_community.document_loaders`, follow these steps:

1. **Check Directory Path**: Ensure that the directory path you are providing exists and is correct.
2. **Install Dependencies**: Make sure all required dependencies are installed, including any external tools like `marker_single` if you are processing PDFs.

Here is a code snippet that demonstrates how to handle these issues:

```python
from pathlib import Path
from langchain_community.document_loaders import DirectoryLoader

# Ensure the directory path is correct
directory_path = Path("C:\\Users\\kepa")
if not directory_path.exists() or not directory_path.is_dir():
    raise ValueError(f"The directory {directory_path} does not exist or is not a directory.")

# Initialize the DirectoryLoader
loader = DirectoryLoader(directory_path)

# Load documents
try:
    documents = list(loader.lazy_load())
    for doc in documents:
        print(doc.page_content)
except Exception as e:
    print(f"An error occurred: {e}")
```

Make sure to replace `"C:\\Users\\kepa"` with the actual path to your directory. Additionally, ensure that any external tools like `marker_single` are installed and available in your system's PATH.

If you encounter dependency issues, you can install the required packages using pip:

```sh
pip install langchain_community
pip install aiofiles
pip install unstructured
```

If `marker_single` is not found, you need to install it or ensure it is in your PATH:

```sh
# Example installation command for marker_single
pip install marker_single
```

By following these steps, you should be able to resolve the "directory not found" error and dependency issues <sup>[[1]](https://github.com/explodinggradients/ragas/blob/main/src/experimental/ragas_experimental/testset/loaders/ragas_loader.py)</sup>.

@dosu ImportError: failed to find libmagic.  Check your installation
Please note that I'm using python 3.12

<!-- Answer -->
To resolve the `ImportError: failed to find libmagic` issue, you can use the `RAGASLoader` class from the `ragas` repository, which does not rely on `libmagic` and is compatible with Python 3.12. Here is an example of how to use it:

```python
from pathlib import Path
from ragas_experimental.testset.loaders.ragas_loader import RAGASLoader

# Ensure the directory path is correct
directory_path = Path("C:\\Users\\kepa")
if not directory_path.exists() or not directory_path.is_dir():
    raise ValueError(f"The directory {directory_path} does not exist or is not a directory.")

# Initialize the RAGASLoader
loader = RAGASLoader(directory_path)

# Load documents
try:
    documents = list(loader.lazy_load())
    for doc in documents:
        print(doc.page_content)
except Exception as e:
    print(f"An error occurred: {e}")
```

This approach avoids the `libmagic` dependency and should work seamlessly with Python 3.12 <sup>[[1]](https://github.com/explodinggradients/ragas/blob/main/src/experimental/ragas_experimental/testset/loaders/ragas_loader.py)</sup>.

from experimental.ragas_experimental.testset.loaders.ragas_loader import RAGASLoader
the package not found error arises after using the above statement
@dosu

<!-- Answer -->
To resolve the `PackageNotFoundError` when trying to import `RAGASLoader` from `experimental.ragas_experimental.testset.loaders`, ensure that the `ragas_experimental` package is correctly installed and accessible in your Python environment. The import statement in `src/experimental/ragas_experimental/testset/loaders/__init__.py` should be:

```python
from ragas_experimental.testset.loaders.ragas_loader import RAGASLoader

__all__ = ["RAGASLoader"]
```

Make sure that the `ragas_experimental` package is installed and that your Python path includes the directory containing the `ragas_experimental` package. You can install the package using pip if it is available on PyPI, or ensure that the package directory is correctly structured and accessible <sup>[[1]](https://github.com/explodinggradients/ragas/blob/main/src/experimental/ragas_experimental/testset/loaders/__init__.py)</sup>.

ModuleNotFoundError: No module named 'ragas_experimental'
@dosu it isn't on PyPI too

<!-- Answer -->
To resolve the `ModuleNotFoundError: No module named 'ragas_experimental'` if the package isn't available on PyPI, you can install the package directly from the source. Here is how you can do it:

1. **Clone the repository** (if it's hosted on a platform like GitHub):
    ```sh
    git clone https://github.com/explodinggradients/ragas.git
    ```

2. **Navigate to the directory** containing the `ragas_experimental` module:
    ```sh
    cd ragas/src/experimental
    ```

3. **Install the module** using `pip`:
    ```sh
    pip install .
    ```

Alternatively, if the project uses Poetry for dependency management (as indicated by the presence of a `pyproject.toml` file), you can install the module using Poetry:

1. **Navigate to the directory** containing the `pyproject.toml` file:
    ```sh
    cd ragas/src/experimental
    ```

2. **Install the module** using Poetry:
    ```sh
    poetry install
    ```

This will install the `ragas_experimental` module from the local source, making it available for import in your Python environment <sup>[[1]](https://github.com/explodinggradients/ragas/blob/main/src/experimental/ragas_experimental/__init__.py)</sup><sup>[[2]](https://github.com/explodinggradients/ragas/blob/main/src/experimental/pyproject.toml)</sup><sup>[[3]](https://github.com/explodinggradients/ragas/blob/main/src/experimental/DEVELOPMENT.md)</sup>.
