Passing run object between files#

Once you've created a run with the init_run() function, you can pass it around multiple Python files.

You can use the run object to populate parameters of functions in other files. This way, you can work with a larger codebase and log from multiple Python scripts at once.

Example#

# Import from "utils.py" file
from utils import log_images_epoch

# Create run in project
run = neptune.init_run()  # (1)!

# Log metrics in the same file
run["train/acc"] = 0.95
run["train/f1"] = 0.65

# Log by using an imported function, passing "run" as the argument
log_images_epoch(run=run)
  1. We recommend saving your API token and project name as environment variables. If needed, you can pass them as arguments when initializing Neptune: neptune.init_run(project="workspace-name/project-name", api_token="Your Neptune API token here")
# "run" is the Neptune run
def log_images_epoch(run):
    image1 = ...
    image2 = ...

    run["images/img_1"].upload(image1)
    run["images/img_2"].upload(image2)
