Fault-tolerant Training (expert)¶
Audience: Experts looking to enable and handle their own fault-tolerance.
Pre-requisites: Users must have first read Fault-tolrance Training (basic)
Enable fault-tolerant behavior anywhere¶
To enable fault tolerance on your own cloud or cluster environment enable the PL_FAULT_TOLERANT_TRAINING environment variable:
PL_FAULT_TOLERANT_TRAINING=1 python script.py
Although Lighting will now be fault-tolerant, you’ll have to handle all the nuances of making sure the models are automatically restarted.
Note
This complexity is already handled for you if you use lightning-grid.
Enable fault-tolerant behavior on your own cluster¶
The simplest way to enable fault-tolerant behavior is to enable lightning-grid to work on your on-prem cluster or cloud environment which will handle all the nuances of fault-tolerant training at scale.
