[Bug]: ModuleNotFoundError: No module named 'enterprise' When Using litellm==1.48.1 in Google Colab

[Wajid160]

Bug Description
Running a Python script in Google Colab using litellm==1.48.1 throws ModuleNotFoundError: No module named 'enterprise' when importing LitellmModel from agents.extensions.models.litellm_model. The same script worked fine the previous night, suggesting a recent environment or dependency change.

Additional Context

• The error originates from litellm/responses/litellm_completion_transformation/transformation.py, attempting to import from enterprise.enterprise_hooks.session_handler.
• Similar issue reported in #5909 — likely related to a missing or premium enterprise module.
• Colab’s runtime may have reset, causing package mismatches.

Possible Causes

• Missing Enterprise Module: enterprise might be a separate (undocumented) package like litellm-proxy-enterprise.
• New Dependency: litellm==1.48.1 may have introduced this dependency unexpectedly.
• Colab Reset: Temporary Colab environment reset could have lost critical packages.
• Undocumented Feature: enterprise might belong to a premium feature and should be handled optionally.

Suggested Fix

• Clarify if enterprise is required for standard usage or is a separate installation.
• If optional, update litellm to handle missing imports gracefully (e.g., try-except block).
• Recommend a stable, verified litellm version or pin dependencies to avoid such issues.
• Provide clear installation guidance for any enterprise-related modules.

Workarounds Attempted

• Reinstalled litellm==1.48.1 and agents; error persists.
• Tried !pip install litellm-proxy-enterprise; package not found on PyPI.
• Downgrading to litellm==1.40.14 (which might avoid the dependency) was considered but not yet tested.
