Hi Ryosuke, Unfortunately, there is currently no arts-lectures package available for ARTS 2.4. The master branch is not compatible with any released ARTS version.
We are in the process of updating the lecture package to be compatible with the latest pre-release version (2.5.6) of ARTS. But note that this is a work in progress and currently only exercises 1, 2, 4 and 7 have been updated to work with that version. The develop branch of the arts-lectures package can be found here: https://github.com/atmtools/arts-lectures/tree/develop The README contains links to matching catalog versions. While the source code for ARTS 2.5.6 is available on Github[1], the easiest way to get up and running is to create an environment with conda, preferably from mambaforge/miniforge[2]. This will install a precompiled version of PyARTS and thus eliminating the need to compile ARTS yourself: conda create -n pyarts -c rttools -c conda-forge python=3.10 pyarts ipympl jupyterlab typhon conda activate pyarts export ARTS_DATA_PATH=/home/username/arts-cat-data-snapshot-arts-2.5.6:/home/username/arts-xml-data-snapshot-arts-2.5.6 jupyter-lab arts-lectures/exercises/01-molecule_spectra/absorption.ipynb Adapt the ARTS_DATA_PATH according to the locations on your system.
