PyJulia is a Python package that provides a bridge between Python and Julia, allowing you to call Julia functions from Python and vice versa. It integrates with IPython/Jupyter. Current version is 0.6.2, supporting Python >=3.4. Release cadence is irregular, with updates for compatibility with new Julia and Python versions.

Verified usage

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

Julia

✓ from julia import Julia

✗ from julia.core import Julia

Public API is from julia import Julia. Direct import of core is discouraged and may break.

Main

✓ from julia import Main

Initialize Julia and call a Julia function. Note: compiled_modules=False is often needed on first run to avoid segfaults.

from julia import Julia js = Julia(compiled_modules=False) from julia import Base Base.println("Hello from Julia")

Debug

Known issues

breakingPyJulia 0.6.0 dropped support for Python 2.7. Upgrade Python to 3.x.

fix

Use Python 3.4+

affects: >=0.6.0

gotchaIf Julia is not installed or not in PATH, from julia import Julia will raise an error. Missing Julia installation is the most common issue.

fix

Install Julia from julialang.org/downloads/ and ensure julia command is available in your terminal.

affects: all

gotchaOn Windows, compiled_modules=True (default) may cause segfaults. It is recommended to use compiled_modules=False if you encounter crashes.

fix

Initialize Julia with Julia(compiled_modules=False)

affects: all

deprecatedThe function julia.install() is no longer needed in recent versions; PyJulia automatically installs the required Julia package PyCall.jl when first used.

fix

Do not call julia.install(). Just import and use Julia().

affects: >=0.5.0

Errors

Common errors & fixes

Julia not found. Please install Julia from https://julialang.org/downloads/

Julia is not installed or not in PATH.

fix

Download and install Julia, then make sure julia command is accessible in your terminal/environment.

UnicodeEncodeError: 'ascii' codec can't encode character

PyJulia fails to encode non-ASCII characters when printing from Julia.

fix

Set environment variable PYTHONIOENCODING=utf-8

Segmentation fault (core dumped)

Compiled modules cache conflicts, often on first run or after Julia updates.

fix

Initialize Julia with Julia(compiled_modules=False) or clear ~/.julia/compiled
