I’m building an application using the `paraview.simple` module. To enable CI and generally simplify things, I’d like to include ParaView (PV) as a dependency of my project (I use `poetry`, my dependencies are in a `pyproject.toml` file). I see there exists a `paraview` Anaconda package [here](https://anaconda.org/conda-forge/paraview), but I couldn’t find an equivalent on PyPI. Hence the question, how can I add PV as a dependency? Is it at all possible?

If not possible, what’s the best option? I can think of:

- asking the user to install PV manually in the documentation and create the necessary symlinks in the virtual environment
- scripting the download of PV and creation of symlinks

I’m aware I could use `pvpython` instead of a separate virtual environment, but that doesn’t suit my needs.

Any help would be greatly appreciated!

You can use PV with a virtual-environment

Thanks for your message! Could you elaborate a bit:

- What do you mean exactly?
- How do I do that? Do you have a reference?

He means that you can make a venv and tell ParaView (`pvpython`) to use that. ParaView is really difficult to make into a wheel at this time, so PyPI distribution isn’t really on the schedule at all.

```auto
python3.10 -m venv py-env # make sure you use the same python version as your instance of paraview uses
source py-env/bin/activate
pip install <packages you need>
<paraview>/bin/pvpython script.py --venv ./py-env

```

Thanks @ben.boeckel & @Christos_Tsolakis for the replies. I’ll test this approach and report back if I run into issues. I also have to think a bit more about how this fits into my goal.

Hi,

```
 Just to make sure before spending too much time on pvpython using an extra virtual 

```

environment … Am I right in assuming that I can add a virtual environment without building  
ParaView from scratch ? I’m actually using Paraview (5.13.0) **binaries** which come with python 3.10.13. (So I created my own virtual environment pvextra based on python 3.10.13, installing a few python modules: xarray, pyvista and geovista).

I’m getting this memory corruption error …

pvpython --venv /home/jmb001/.venv/pvextra my\_script.py  
Error message:

```auto
pvpython --venv /home/jmb001/.venv /path/to/script.py  

```

Also side note, PyVista will install VTK inside the venv which will conflict with the one available on ParaView. So make sure you remove vtk from the venv.

Thanks Sebastien,

```
 Oupss! vtk ... good point.

 Sorry to insist: :-)
 I assume adding my virtual environment without building ParaView from scratch is OK ?
