Dask DataFrame

Hello community.

Were you able to solve this, @DrTodd13 ?

I am having the same issue with an environment setup with UV.

OS is Windows 11 Enterprise, Version 10.0.26100 Build 26100.
Running from VS Code 1.98.2.
Running with Python 3.13.
Dependencies are resolved with “uv sync”.

pyproject.toml:

[project]
name = "dask-sql-example"
version = "0.1.0"
description = "Dask SQL Example"
readme = "README.md"
requires-python = ">=3.13"
dependencies = [
    "dask[complete]>=2025.2.0",
    "dask-sql>=2024.5.0",
    "dask-expr>=2.0.0",
    "distributed>=2025.2.0",
    "pandas>=2.2.3",
    "pyarrow>=19.0.1",
]

main.py:

import dask.dataframe as dd
import pandas as dp
from dask_sql import Context


def start() -> None:
        query = "select line_item_product_code from raw_data"

        pdf = dp.DataFrame(
            {
                "line_item_product_code": ["AmazonEC2", "AmazonRDS"],
                "line_item_line_item_type": ["RIFee", "DiscountedUsage"],
                "pricing_purchase_option": ["All Upfront", "Partial Upfront"],
                "reservation_reservation_arn": ["arn:aws:1", "arn:aws:2"],
                "line_item_net_unblended_rate": [1.0, 2.0],
            }
        )
        dataframe = dd.from_pandas(pdf, npartitions=2)

        c = Context()
        c.create_table("raw_data", dataframe)
        result = c.sql(query).compute()
        print(result.head())


if __name__ == "__main__":
    start()

Exception stack:

Traceback (most recent call last):
  File "c:\code\dask-sql-example\app\main.py", line 27, in <module>
    start()
    ~~~~~^^
  File "c:\code\dask-sql-example\app\main.py", line 21, in start

    from dask_expr.io.parquet import ReadParquet
ModuleNotFoundError: No module named 'dask_expr.io'

Is this information enough?
Any help is appreciated.

Thank you.
