Installing runtime dependencies

If DLite has been compiled with Python, Fortran, librdf or HDF5 support, you will need the corresponding runtime libraries. These are normally installed together with the corresponding development libraries. But if you are distributing DLite, the corresponding runtime libraries will have to be installed separately. On Ubuntu, they can be installed with

sudo apt install python3 gfortran librdf libhdf5

When DLite is compiled with Python bindings, additional runtime features may be enabled by installing one of more of the following optional Python packages

• tripper, used for property mappings

• pint, used for units conversion in property mappings

• pydantic, used for testing support for pydantic models

• typing_extensions, needed by pydantic v2

• rdflib, used by pyrdf storage plugin.

• PyYAML, used by yaml storage plugin

• psycopg2, used by postgresql storage plugin Note that in some cases a GSSAPI error is raised when using psycopg2 by pip installing psycopg2-binary. This is solved by installing from source as described in their documentation.

• pandas, used by the csv storage plugin

• requests, used by http storage plugin

• jinja2, used by template storage plugin

• pymongo, used by the mongodb storage plugin

• [redis], used by the redis storage plugin

• [minio], used by the minio storage plugin

These optional dependencies can be installed with

pip install -r requirements_full.txt

Separate requirements can also be installed for just property mappings

pip install -r requirements_mappings.txt

for development

pip install -r requirements_dev.txt

or for building the documentation

pip install -r requirements_doc.txt
