Hi all,

I am trying to reproduce the tutorial [Test problem 2: Flow past a cylinder (DFG 2D-3 benchmark) — FEniCSx tutorial](https://jorgensd.github.io/dolfinx-tutorial/chapter2/ns_code2.html) to learn how to load the mesh and boundary markers in Dolfinx.

```auto
from dolfinx.io import distribute_entity_data, cell_perm_gmsh
from dolfinx.graph import create_adjacencylist

```

For the first line, the error that I am getting is:

> ImportError: cannot import name ‘distribute\_entity\_data’ from ‘[dolfinx.io](http://dolfinx.io)’ (/usr/local/dolfinx-real/lib/python3.8/dist-packages/dolfinx/io.py)  
> ImportError: cannot import name ‘distribute\_entity\_data’ from ‘[dolfinx.io](http://dolfinx.io)’ (/usr/local/dolfinx-real/lib/python3.8/dist-packages/dolfinx/io.py)

and for the second line:

> ModuleNotFoundError: No module named ‘dolfinx.graph’

I guess that the functions have been deleted or moved to other directories.  
Does anyone know where these functions have been located?

Thanks in advance.

Which version of dolfinx are you running?  
Could you run the following:

```python
python3 -c "import dolfinx; import dolfinx.common; print(dolfinx. __version__ , dolfinx.common.git_commit_hash)"

```
