!!! success "Now Available on PyPI!"
    Semantica is officially published on PyPI! Install it with a single command: `pip install semantica`

!!! note "System Requirements"
    Semantica requires Python 3.8 or higher. For best performance, we recommend Python 3.10+.

## Prerequisites

Before installing Semantica, ensure you have:

```bash
pip install semantica
```

This installs Semantica with all core dependencies.

!!! tip "Virtual Environment"
    We recommend installing Semantica in a virtual environment to avoid dependency conflicts. Use `python -m venv venv` to create one, then activate it before installing.

You can also check the installation:

```bash
pip show semantica
```

    python -m venv venv

    # Activate (Windows)
    venv\Scripts\activate

    # Activate (Linux/Mac)
    source venv/bin/activate

    # Install Semantica
    pip install semantica
    ```

=== "conda"

    ```bash
    # Create conda environment
    conda create -n semantica python=3.11
    conda activate semantica

    # Install Semantica
    pip install semantica
    ```

## Troubleshooting

### Common Issues

#### ModuleNotFoundError

**Error**: `ModuleNotFoundError: No module named 'semantica'`

**Solutions**:
- Make sure you've activated the correct Python environment
- Verify installation: `pip list | grep semantica`
- Reinstall: `pip install --upgrade semantica`

#### Installation Fails

**Error**: Installation fails with dependency errors

**Solutions**:
- Upgrade pip: `pip install --upgrade pip`
- Install build tools: `pip install build wheel`
- Try installing without optional dependencies first: `pip install semantica --no-deps`

#### GPU Dependencies Fail

**Error**: GPU dependencies fail to install

**Solutions**:
- Install CPU-only version first: `pip install semantica`
- Then add GPU support: `pip install semantica[gpu]`
- Check CUDA compatibility for your system

#### Permission Errors

**Error**: Permission denied during installation

**Solutions**:
- Use `--user` flag: `pip install --user semantica`
- Use virtual environment (recommended)
- On Linux/Mac, avoid using `sudo` with pip
