A Jupyter kernel that delegates to `ipykernel` in the `.venv` environment of a project folder.

Derived from [`poetry-kernel`](https://github.com/pathbird/poetry-kernel), see the [FAQ](https://github.com/goerz/python-localvenv-kernel/blob/master/FAQ.md#how-does-this-kernel-differ-from-poetry-kernel).

See the demo at the December 2023 Jupyter Community Call:

## Installation

The `python-localvenv-kernel` package can be installed via `pip` (`pip install python-localvenv-kernel`) or as a [Conda package](https://github.com/conda-forge/python-localvenv-kernel-feedstock#about-python-localvenv-kernel-feedstock) (`conda install python-localvenv-kernel`).

It must be installed into the same environment as the Jupyter server, see [Usage](#usage) below.

## Usage

* Jupyter and the `python-localvenv-kernel` package should be installed in the same environment

* The project folder must have a virtual (project) environment instantiated in a subfolder `.venv`. The name of folder can be overridden by setting the environment variable `KERNEL_VENV` (see [FAQ](https://github.com/goerz/python-localvenv-kernel/blob/master/FAQ.md#how-can-i-change-the-directory-for-the-virtual-environment))

* The project environment must include the `ipykernel` package (but not `jupyter`)

* Start Jupyter from the project folder

* Select the "Python (local .venv)" kernel
