Pre-release
This release is a pre-release and may not be stable for production use.
AMPEL-HU-astro
Contributed Ampel units from HU/DESY group
Installing
- Install poetry.
- Configure poetry to create virtualenvs in the project:
poetry config virtualenvs.in-project true. This makes it easier to work with IDEs like VSCode. git clone https://github.com/AmpelProject/Ampel-HU-astro.git; cd Ampel-HU-astro- Check your virtualenv setup with
poetry env info. The output should include:
If not, point poetry at an installation of Python >=3.12 with e.g.Virtualenv Python: 3.12.xpoetry env use python3.12(assuming that python3.12 is in yourPATH) poetry install -E "ztf sncosmo extcats" --with notebookcd notebookspoetry run jupyter notebook
This will allow a number of Demo / access / development notebooks to be run. Note that most of them requires an access token if data is to be retrieved.
Pitfalls
- lightgbm expects to find OpenMP on your system. If you see an error message like
OSError: libgomp.so.1: cannot open shared object file: No such file or directory, you will need to install OpenMP with e.g.brew install libomp(macOS) orapt-get install libgomp1(Ubuntu). - to install with parsnip support, `poetry install -E "elasticc" --with notebook
