meshpro / pyfvm Goto Github PK

I have installed pyfvm, voropy, and meshzoo from github clones. When I run your Poisson example, I get the error:

AttributeError: 'module' object has no attribute 'mesh_tri'

If I instead import voropy and access mesh_tri from there, I then get the error:

ValueError: sort array is read-only

regarding the coordinate array m.cells() from mshr. Perhaps you want to copy this instead?

Not sure if this is the right place to ask about this since the repo seems to be empty (?) but this is where the PyPI package page links.

I cannot install pyfvm with pip.

Steps to reproduce:

conda create -n pyfvm python=3
conda activate pyfvm
pip install pyfvm 

Output:

ERROR: Cannot install pyfvm==0.4.1 and pyfvm==0.4.3 because these package versions have conflicting dependencies.

The conflict is caused by:
    pyfvm 0.4.3 depends on meshplex<0.19.0 and >=0.18.0
    pyfvm 0.4.1 depends on meshplex<0.19.0 and >=0.18.0

To fix this you could try to:
1. loosen the range of package versions you've specified
2. remove package versions to allow pip attempt to solve the dependency conflict

Hi,

I'm trying to install pyfvm via pip, as suggested in the guide, the procedure ends up with the following error:

Moreover, I cannot find any repository for the code-extract package on the web.

Thank you very much for your help,

Hi,

I think there' s a problem, since running the Poisson 1-d example it gives me an error AttributeError: 'Mesh' object has no attribute 'node_coords'.

The complete trace is

I see that the meshplex library has been updated in June, while pyfvm has the last commit 8 months ago. Maybe the problem comes from this ?

Thank you for the wonderful library btw

pip install leave an error:

should be fixed by adding it in setup.py

I have installed pyfvm with pip, but while running a code, I am getting the following license error:

Error: Unable to find valid license for product ID 973948c2-ac9b-4a78-b37b-2adaafcf5523.

Add a license with

slim install <your-license>

(KG_NOT_FOUND)

Can anybody point me to the correct license? Thanks!
