Package: wandb-allennlp
wandb-allennlpUtilities and boilerplate code which allows usingWeights & Biasesto tune the hypereparameters for any AllenNLP modelwithout a single line of extra code!What does it do?Log a single run or a hyperparameter search sweep without any extra code, just using configuration files.UseWeights & Biases'bayesian hyperparameter search engine + hyperband in any AllenNLP project.Quick startInstallation$ pip install wandb-allennlp
$ echo wandb_allennlp >> .allennlp_pluginsLog a single runCreate your model using AllenNLP along with atraining configurationfile as you would normally do.Add a trainer callback in your config file. Use one of the following based on your AllenNLP version:...,

trainer: {
    type: 'callback',
    callbacks: [
      ...,
      {
        type: 'wandb_allennlp',
        files_to_save: ['config.json'],
        files_to_save_at_end: ['*.tar.gz'],
      },
      ...,
    ],
    ...,
}

...Execute theallennlp train-with-wandbcommand instead ofallennlp train. It supports all the arguments present inallennlp train. However, the--overrideshave to be specified in the--kw valueor--kw=valueform, wherekwis the parameter to override andvalueis its value. Use the dot notation for nested parameters. For instance,{'model': {'embedder': {'type': xyz}}}can be provided as--model.embedder.type xyz.allennlp  train-with-wandb model_configs/my_config.jsonnet --include-package=package_with_my_registered_classes --include-package=another_package --wandb-run-name=my_first_run --wandb-tags=any,set,of,non-unique,tags,that,identify,the,run,without,spacesHyperparameter SearchCreate your model using AllenNLP along with atraining configurationfile as you would normally do. For example:local data_path = std.extVar('DATA_PATH');
local a = std.parseJson(std.extVar('a'));
local bool_value = std.parseJson(std.extVar('bool_value'));
local int_value = std.parseJson(std.extVar('int_value'));

}Create asweep configurationfile and generate a sweep on the wandb server. Note that the tied parameters that are accepted through environment variables are specified using the prefixenv.in the sweep config. For example:name: parameter_tying_test_console_script_v0.2.4
program: allennlp
command:
  - ${program} #omit the interpreter as we use allennlp train command directly
  - "train-with-wandb" # subcommand
  - "configs/parameter_tying_v0.2.4.jsonnet"
  - "--include-package=models" # add all packages containing your registered classes here
  - "--include-package=allennlp_models"
  - ${args}
