opendp-logger 0.1.6

A logger wrapper for OpenDP to keep track of, import, export the AST

OpenDP Logger

The OpenDP logger makes it possible to serialize and deserialize OpenDP Measurements/Transformations to/from JSON.

Serialize

Enable logging (globally) before you build your transformations and/or measurements:

from opendp_logging import enable_logging
enable_logging()

Once this is enabled, Transformations/Measurements have a method .to_json() that returns a JSON string.

Deserialize

Deserialize a JSON string into a Transformation/Measurement by invoking opendp_logger.make_load_json.

Example

from opendp_logger import enable_logging
from opendp.mod import enable_features

enable_logging()
enable_features("contrib")

import opendp.transformations as trans

preprocessor = (
    # load data into a dataframe where columns are of type Vec<str>
    trans.make_split_dataframe(separator=",", col_names=["hello", "world"])
    >>
    # select a column of the dataframe
    trans.make_select_column(key="income", TOA=str)
)

# the ast object maintained in the pipeline
print("ast:", preprocessor.ast)

# serialize the ast to json
json_obj = preprocessor.to_json()
print("json:", json_obj)

from opendp_logger import make_load_json

# reconstruct the obj from the json string
test = make_load_json(json_obj)

print(test.ast)
