On Windows: venv\\Scripts\\activate\npip install comet_ml neptune\n```\n\n## Usage\n\n### Basic Usage\n\n```bash\npython3 neptune_exporter.py \\\n  --neptune-project-name \"workspace/project-name\" \\\n  --neptune-api-token \"your-neptune-api-token\" \\\n  --comet-workspace \"your-workspace\" \\\n  --comet-project-name \"your-project-name\"\n```\n\nMake sure to set your Comet API key as an environment variable:\n\n```bash\nexport COMET_API_KEY=\"your-comet-api-key\"\n```\n\n### Using Environment Variables\n\nYou can also use environment variables instead of command-line arguments:\n\n```bash\nexport NEPTUNE_PROJECT=\"workspace/project-name\"\nexport NEPTUNE_API_TOKEN=\"your-neptune-api-token\"\nexport COMET_WORKSPACE=\"your-workspace\"\nexport COMET_PROJECT_NAME=\"your-project-name\"\nexport COMET_API_KEY=\"your-comet-api-key\"\n\npython3 neptune_exporter.py \\\n  --neptune-project-name \"$NEPTUNE_PROJECT\" \\\n  --comet-workspace \"$COMET_WORKSPACE\" \\\n  --comet-project-name \"$COMET_PROJECT_NAME\"\n```\n\n## Getting Your Credentials\n\n### Neptune\n\n- **Project name**: Format is `workspace/project-name`\n- **API token**: Get it from [Neptune Settings](https://app.neptune.ai/get_my_api_token)\n\n### Comet\n\n- **Workspace**: Your Comet workspace name\n- **Project name**: The Comet project name (will be created if it doesn't exist)\n- **API key**: Get it from [Comet Settings](https://www.comet.com/settings/profile)\n\n## What Gets Exported\n\nThe exporter transfers the following data from Neptune to Comet:\n\n- **Hyperparameters**: All parameters from `parameters` or `hyperparameters` namespace\n- **Metrics**: Training and validation metrics including:\n  - `train/loss`, `train/accuracy`\n  - `val/loss`, `val/accuracy`\n  - `training/train/epoch/accuracy`, `training/train/epoch/loss`\n  - `training/train/batch/accuracy`, `training/train/batch/loss`\n  - `training/test/epoch/accuracy`, `training/test/epoch/loss`\n  - `training/test/batch/accuracy`, `training/test/batch/loss`\n- **Final metrics**: Metrics from the `final` namespace\n- **Metadata**: Additional metadata from the `metadata` namespace\n- **Owner information**: User information from `sys/owner`\n\n## Verify the Migration\n\nAfter running the exporter, check the output for experiment URLs. Each exported run will display a Comet experiment URL:\n\n```\ncreated comet experiment: https://www.comet.com/your-workspace/your-project-name/experiment-id\n```\n\nVisit these URLs to verify that all data was transferred correctly.\n\n## Troubleshooting\n\n### Missing dependencies\n\nIf you get `ModuleNotFoundError`, make sure you've installed the required packages:\n\n```bash\npip install comet_ml neptune\n```\n\n### Invalid API token\n\nIf you get a `NeptuneInvalidApiTokenException`, verify your Neptune API token is correct. You can get it from [Neptune Settings](https://app.neptune.ai/get_my_api_token).\n\n### Project not found\n\nMake sure the Neptune project name is in the format `workspace/project-name` and that you have access to it.\n\n### No data transferred\n\nIf experiments are created but no data appears, check:\n- The Neptune runs contain data in the expected paths (`parameters`, `train/loss`, etc.)\n- Your Comet API key has write permissions to the workspace\n- The script completed without errors\n\n## License\n\nApache 2.0 License\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcomet-ml%2Fneptune-to-comet-exporter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fcomet-ml%2Fneptune-to-comet-exporter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fcomet-ml%2Fneptune-to-comet-exporter/lists"}
