Logging¶

The log of the FL results looks like the following:

  Iter     Local[s]    Global[s]     Valid[s]      Iter[s]   Elapsed[s]  TestAvgLoss TestAccuracy     Prim_res     Dual_res    Penal_min    Penal_max

The contents can be modified by revising log_title, log_iteration, and log_summary in src/appfl/misc/utils.py.

FL results are recorded in .txt in a predefined directory. To set the directory and the filename, for example, one can revise the configurations as follows:

# Loading Configurations
from OmegaConf import OmegaConf
from appfl.config import Config
cfg = OmegaConf.structured(Config)
# FL Outputs
cfg.output_dirname = "./outputs"
cfg.output_filename = "result"
