blaze

library0.10.1pypypiunverified

Blaze is a Python library for expressing computations involving tabular, relational, and streaming data. It provides a unified interface for querying data from various backends (e.g., CSV, SQL, HDF5, Parquet, MongoDB) and delegates execution to the appropriate engine. The current version is 0.10.1, but the project is in maintenance mode with no new features; users are encouraged to migrate to dask or other modern alternatives.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Data

✓ from blaze import Data

✗ from blaze.core import Data

Data is the main entry point for wrapping data sources. The old submodule path is incorrect.

compute

✓ from blaze import compute

✗ from blaze.core.compute import compute

The compute function is available at the top-level; deep imports break between versions.

Load a CSV file and display the first few rows. Blaze supports many backends; for production, consider migrating to dask.

from blaze import Data d = Data('data.csv') print(d.head())

Known issues

deprecatedBlaze is in maintenance mode and no longer actively developed. Users are strongly encouraged to migrate to dask or other modern libraries.

fix

Consider using dask.dataframe or pandas for new projects. See https://docs.dask.org for migration guidance.

affects: >=0.10.0

gotchaThe interactive shell and blaze-specific notebook extensions are deprecated and may be removed.

fix

Use standard Python or Jupyter notebooks; avoid starting blaze interactive shell.

affects: >=0.10.0

breakingAPI breaking changes: The `Symbol` and `Expr` classes are considered internal and may change without notice.

fix

Always use the top-level `Data` and `compute` functions; avoid importing from `blaze.expr` directly.

affects: all
