Code

Verified usage

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

vaex.from_csv

✓ import vaex; df = vaex.from_csv('data.csv')

✗ from vaex.core import ...

vaex-core exports symbols via top-level vaex; direct imports from vaex.core are unstable.

Load a CSV into a vaex DataFrame lazily and display first few rows.

import vaex df = vaex.from_csv('https://raw.githubusercontent.com/vaexio/vaex/master/docs/source/data/example.csv') print(df.head())

Debug

Known issues

deprecatedvaex-core is no longer under active development; all development has moved to the 'vaex' meta-package. The vaex-core package should be considered legacy.

fix

Install `vaex` instead of `vaex-core` to get the full suite.

affects: 4.x

breakingImporting from 'vaex.core' directly is not recommended and may break in future releases. Use top-level 'import vaex'.

fix

Replace 'from vaex.core import ...' with 'import vaex' and use vaex.* functions.

affects: >=4.0

gotchavaex-core installs many heavy dependencies (e.g., pyarrow, fastparquet) which can cause version conflicts if not pinned.

fix

Use a virtual environment and consider installing without extras: pip install --no-deps vaex-core, then add only needed deps.

affects: all
