Hi,  
I want to create more than one partition for couette\_flow\_2d but I receive the following error

`$ pyfr import couette_flow_2d.msh couette_flow_2d.pyfrm`

```auto
/home/mahmood/.local/lib/python3.6/site-packages/h5py/ __init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.
from ._conv import register_converters as _register_converters

```

`$ pyfr partition 2 couette_flow_2d.pyfrm .`

```auto

```

How can I fix that?

Hi Mahmood,

You need to install metis as a shared library and add

`export LD_LIBRARY_PATH=/path/to/your/metis/lib:$LD_LIBRARY_PATH`

Cheers,

Niki
