Fix bug due to latest version of PyTorch

Eventually:

- Export models as a zip file.

- Implement training detection model using YOLO

- Implement location net and clustering using PQKMeans

- Implement fine-tuning / training face recognition models

- Pre-condition checks, and failed to launch error messages for processes.
