Launches worker engines into the cluster.
- Syntax
-
launch_workers(n, cpu, memory, nvidia_gpu=0, kernel="python3", script="", code="", env={})
- Parameters
-
- n (int) - The number of engines to launch.
- cpu (float) - The number of CPU cores to allocate to the engine.
- memory (float) - The number of gigabytes of memory to allocate to the engine.
- nvidia_gpu (int, optional) - The number of GPU's to allocate to the engine.
- kernel (str, optional) - The kernel. Can be "r", "python2", "python3" or "scala". This parameter is only available for projects that use legacy engines.
- script (str, optional) - The name of a Python source file the worker should run as soon as it starts up.
- code (str, optional) - Python code the engine should run as soon as it starts up. If a script is specified, code will be ignored.
- env (dict, optional) - Environment variables to set in the engine.
- Example Usage
-
