For each library, also prints the file path it was loaded from, which pip package installed it, and the reverse-dependency tree (via pipdeptree if available) showing what pulled it in. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Signed-off-by: Kajal Jain <kajalj@nvidia.com>

uv is not installed in the RL container. Use /opt/nemo_rl_venv/bin/python directly, with fallbacks to other common locations. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Signed-off-by: Kajal Jain <kajalj@nvidia.com>
