If you have installed Blender from another source instead of from
`Blender.org <https://www.blender.org/download/>`__, such as from your
distro's package repositories, then you may be missing some modules like
``numpy``. Try installing it manually like ``apt install python-numpy``.

5. **I get an error similar to RuntimeError: Instance #1234 not found**
Blender saves and loads projects to a ``.blend`` file. However. the
BlenderBIM Add-on works with native IFC, and this means instead of saving
and loading ``.blend`` files, you should instead save and load the ``.ifc``
project.
If you have opened a ``.blend`` file, there is a risk that the contents of
the ``.blend`` session do not correlate to the contents of the ``.ifc``,
which can cause this error. Unless you are an advanced user, only save and
load ``.ifc`` files.
