akernel
An asynchronous Python Jupyter kernel built on AnyIO:
- runs in a separate process or in-process.
- supports top-level
await.
Install
For a standalone, out-of-process kernel, install the subprocess extra:
pip install "akernel[subprocess]"
This will give you a Python 3 (akernel) in JupyterLab.
akernel can also run in-process with Jupyverse.
Install it with:
pip install "fps-akernel-task"
This will give you both Python 3 (akernel) and Python 3 (akernel-thread) kernels
in JupyterLab.
In-process kernels
They run in Jupyverse's process, so running blocking user code in the kernel will also block Jupyverse.
akernel-thread is an in-process kernel that runs user code in a separate thread,
which won't block Jupyverse.
Limitations
- Cell output redirection currently uses the kernel's
printfunction rather than capturing all writes tostdoutandstderr. - In-process kernels cannot be interrupted while running blocking code.
