No module named 'splink.duckdb.linker

Hi,

Cool project!! When I try to run the demo code below I get No module named 'splink.duckdb.linker. Any ideas on what is going wrong? The code is below. Thank you!

from splink.duckdb.linker import DuckDBLinker
import splink.duckdb.comparison_library as cl
import splink.duckdb.comparison_template_library as ctl
from splink.duckdb.blocking_rule_library import block_on
from splink.datasets import splink_datasets
import logging, sys
logging.disable(sys.maxsize)

df = splink_datasets.fake_1000

settings = {
"link_type": "dedupe_only",
"blocking_rules_to_generate_predictions": [
block_on("first_name"),
block_on("surname"),
block_on("email")
]
}

linker = DuckDBLinker(df, settings)

linker.cumulative_num_comparisons_from_blocking_rules_chart()

What do you get if you run splink.__version__?

I am using jupyterlab on Posit. I installed it and got: NameError: name 'splink' is not defined.. Interesting..

[RobinL]

Difficult to tell but it sounds like for some reason it hasn't installed into the right place and so python can't see it

It ended up being due to the version of python. It was 3.6.. I made a new environment using 3.11 and it works perfectly!! Thank you!!

thanks for letting us know!

Hi Robin, Silly question for you: Have you seen something like this screen shot below before? It doesn’t really look like any of the fields is particularly useful.. Am I missing something? Is there anything that one can do? Thank you!!
