Usage: python gen_yaml.py [OPTIONS] TEMPLATE-FILE H-PARAMETER-FILE
Produce yaml files given a template and hyper-parameters ranges
-o FILE, --out=FILE file name on which it builds yaml files {{1,2,3,...}}
default = TEMPLATE-FILE{{1,2,3,...}}.yaml
-f, --force Force yaml files creation even if files with th
same name already exist
-s, --search=MODE Search mode.
default : fix-grid-search
fix-grid-search : Vary hyper-parameters one at a
time, keeping the others to a
default value.
full-grid-search : Compute all possible combinations
of hyper-parameters values that
has been generated
random-search : Generate random values for every
hyper-parameter given the range
specified. Should be used with
a random generation mode, a warning
message will show up otherwise.
-g, --generate=MODE Generation mode. Applied to every hyper-parameter with
default value. Locally defined generation mode has predominance
default = log-uniform
default, {generation_modes}
-v, --verbose Verbose mode
File configurations:
Yaml template
Use %(save_path)s for the filename of the yaml template.
The file name to save .pkl models in the yaml file will be the same as the
yaml file name. For a file test1.yaml, save_path will be replaced by test1.
Look at the template.yaml file for an example.
Hyper parameters configuration file
# Hyper-parameters min max how much (optional generation mode)
Example:
python gen_yaml.py --out=mlp template.yaml hparams.conf
