Passing local data

If you have a function that needs access to some data not present in your Python files themselves you have a few options for bundling that data with your Modal app.

Passing function arguments

The simplest and most straight-forward way is to read the data from your local script and pass the data to the outermost Modal function call:

import json


@app.function()
def foo(a):
    print(sum(a["numbers"]))


@app.local_entrypoint()
def main():
    data_structure = json.load(open("blob.json"))
    foo.remote(data_structure)

Any data of reasonable size that is serializable through cloudpickle is passable as an argument to Modal functions.

Refer to the section on global variables for how to work with objects in global scope that can only be initialized locally.

Including local files

For including local files for your Modal Functions to access, see Defining Images.
