Sure. That was the plan eventually.

I wasn't sure how people would want it tho.

I'll add args_json and args_json_file Where the latter writes a file and gives you back the filename

May as well add args_json while we're at it 😎

Added, please take another look

This sweep config is fun:

program: train-no-hyphens.py
method: grid
# Parameters to search over
parameters:
  optimizer:
    values: ["sgd", "adam"]
  flag1:
    values:
    - false
    - true
  flag2:
    values:
    - false
    - true
command:
    - ${env}
    - python
    - ${program}
    - ${args_no_hyphens}
    - ${args}
    - ${args_json}
    - ${args_json_file}

The filename is relative right now. which i think is fine, but could cause some issues, I want to leave it that way until looking into file path issues (there is a ticket for it already)

This is the result:

ARG 0 train-no-hyphens.py
ARG 1 flag1=True
ARG 2 flag2=True
ARG 3 optimizer=adam
ARG 4 --flag1=True
ARG 5 --flag2=True
ARG 6 --optimizer=adam
ARG 7 {"flag1": true, "flag2": true, "optimizer": "adam"}
ARG 8 wandb/sweep-9l51kef7/config-7duf503q.json
