Common Causes of the Error

The error “No module named ‘llama_models.cli.model’” typically stems from several underlying issues:

Environment Conflicts: Anaconda environments can interfere with system-wide Python installations, causing import issues. When you install llama-models in one environment but try to run it from another, the modules aren’t accessible.

Incomplete Installation: The package may not have been fully installed, or certain submodules might be missing. This can happen during interrupted installations or when network issues prevent complete package downloads.

Dependency Issues: Missing or incompatible dependencies required by the llama_models.cli.model module can trigger import failures. The llama-models package has several dependencies that must be properly installed.

Path Issues: Python’s module search path might not include the directory where llama_models.cli.model is located, especially if you’re using virtual environments or have multiple Python installations.

Note: This error is particularly common with newer versions of llama-models (0.3.0+) and Python 3.12, as the package structure and dependencies have evolved significantly.

Step-by-Step Troubleshooting Solutions

Solution 1: Reinstall llama-models in the Correct Environment

# Activate your conda environment first
conda activate your_environment_name

# Uninstall the existing package
pip uninstall llama-models

# Clean pip cache
pip cache purge

# Reinstall with all dependencies
pip install llama-models

Solution 2: Use pip with Force Reinstall and Upgrade

# Force complete reinstallation
pip install --force-reinstall --upgrade llama-models

# If that fails, try with --no-cache-dir
pip install --no-cache-dir --force-reinstall --upgrade llama-models

Solution 3: Verify Package Installation Structure

After installation, check if the required modules exist:

# Check if the module is properly installed
python -c "import llama_models.cli.model; print('Module found successfully')"

# If that fails, check the package structure
python -c "import pkg_resources; print([d.project_name for d in pkg_resources.working_set])" | grep llama

Solution 4: Fix Environment Path Issues

# Add the package to your Python path
export PYTHONPATH="$PYTHONPATH:/path/to/your/python/site-packages"

# Or add it to your conda environment
conda env config vars set PYTHONPATH="$PYTHONPATH:/path/to/your/python/site-packages"

Solution 5: Install Missing Dependencies Manually

Based on the research findings, some users encountered missing dependencies like pkg_resources:

# Install commonly missing dependencies
pip install setuptools pkg_resources

Pro Tip: If you’re using Windows, ensure you’re running the commands in an Anaconda Prompt with administrator privileges, as some installations require elevated permissions.

Alternative Installation Methods

Method 1: Use the Official Llama Stack Installation

According to the llama-stack documentation, you can use uv for better dependency management:

# Install uv package manager
pip install uv

# Use uv to install with proper dependency resolution
uv pip install llama-models

Method 2: Install from Source

If the pip installation continues to fail, try installing directly from the GitHub repository:

# Clone the repository
git clone https://github.com/meta-llama/llama-models.git
cd llama-models

# Install in development mode
pip install -e .

Method 3: Use llama-cpp-python Alternative

If you continue having issues with the official CLI, consider using the more stable llama-cpp-python package:

# Install llama-cpp-python
pip install 'llama-cpp-python[server]'

# Download models directly
python -m llama_cpp.server --model models/llama-model.gguf

Prevention and Best Practices

1. Use Clean Environments

Always create a dedicated environment for llama-models work:

# Create a clean environment
conda create -n llama-env python=3.12
conda activate llama-env

# Install in the clean environment
pip install llama-models

2. Keep Dependencies Updated

Regularly update your packages to avoid compatibility issues:

# Update pip and setuptools
pip install --upgrade pip setuptools wheel

# Update llama-models
pip install --upgrade llama-models

3. Check System Requirements

Ensure your system meets the requirements:

• Python 3.10+ (Python 3.12 may have some compatibility issues)
• Sufficient disk space for model downloads
• Proper network connectivity for package downloads

4. Use Version Pinning

To avoid future issues, pin your package versions:

# Create requirements.txt with specific versions
echo "llama-models==0.3.0" > requirements.txt
pip install -r requirements.txt
