### Production Context: Container Environments

In production ML systems, environment setup must be:
- **Reproducible**: Identical across development, staging, production
- **Lightweight**: Minimal resource footprint for container deployment
- **Scalable**: Support for distributed training environments
- **Robust**: Handle dependency conflicts and version mismatches

**Real-world considerations:**
- Docker containers limit memory and CPU resources
- Kubernetes pods may restart, requiring fast environment initialization
- Dependency management critical for model serving reliability
- Environment drift can cause model performance degradation

When setting up ML environments, why is dependency management more critical than in traditional software?

Consider:
- Model reproducibility across different environments
- Version conflicts between ML libraries (NumPy, PyTorch, etc.)
- Container deployment and resource constraints

YOUR ANALYSIS:

"""

### BEGIN SOLUTION
# ML systems require exact reproducibility for model consistency.
# Version mismatches can cause different numerical results.
# Container environments have strict resource limits.

- Dependency version locking and updates
- Platform differences (macOS, Linux, Windows)
- CI/CD pipeline integration
