 - [x] Manage GPU process crashes
 - [x] Make crash resilient workers
 - [x] Spread droplets to all locations to avoid cpu/network competition on same hardware
-- [ ] Add continuous deployment pipline so workers get updates without shutting down
 - [x] Add option to use multiple HCLOUD API keys (to aggregate multiple accounts into the same swarm)
 - [x] Add Colab compatible notebook with hcould swarm. Swarm ratio is about 5 nodes for 1 colab notebook
 - [x] Add Kaggle automation (launch scripts on Kaggle with GPU)
 - [x] Optimize GPU workflow (separate processes for jobs downloading, inference and uploading)
 - [x] Optimize cloud workers: do not install unnecessary packages, remove swap file, use ramdisk for downloading images
-- [ ] Use SSH and SCP libraries from Python instead of subprocess calls (gpu and worker)
