Common Import and Installation Problems

Problem: ModuleNotFoundError: No module named 'core_evals'

Solution:

# Install missing core evaluation framework
pip install nvidia-lm-eval

# For additional frameworks
pip install nvidia-simple-evals nvidia-bigcode-eval nvidia-bfcl

Problem: Framework for task X not found

Diagnosis:

from nemo_evaluator import show_available_tasks

# Display all available tasks
print("Available tasks:")
show_available_tasks()

Or use the CLI:

nv-eval ls tasks

Solution:

# Install the framework containing the missing task
pip install nvidia-<framework-name>

# Restart Python session to reload frameworks

Problem: Multiple frameworks found for task X

Solution:

# Use explicit framework specification
config = EvaluationConfig(
    type="lm-evaluation-harness.mmlu",  # Instead of just "mmlu"
    # ... other config
)
