Failed to load model class 'CytoscapeModel' from module 'pyvipr' on a fresh install

[kaisengit]

Hey there,

following the the example found on https://pyvipr.readthedocs.io/en/latest/tellurium_examples.html

import tellurium as te
import pyvipr.tellurium_viz as tviz

r = te.loada("""
    J1:S1 -> S2; k1*S1;
    J2:S2 -> S3; k2*S2;
    J3:S4 -> S3; k2*S4;

    k1= 0.1; k2 = 0.2;
    S1 = 10; S2 = 0; S3 = 0; S4 = 20;
""")

tviz.sp_view(r)

I get the following error:

And the jupyerlab plugin was installed yesterday via:

conda install pyvipr -c ortegas
jupyter labextension install @jupyter-widgets/jupyterlab-manager
jupyter labextension install pyvipr

Hi, sorry for the delay! I’ll take a look this weekend!

[ortega2247]

what python version are you using and are you using mac/linux or windows?

Hi Oscar (@ortega2247), were you able to figure out what was going on with this issue?

I'm getting a similar error

Failed to load model class 'CytoscapeModel' from module 'pyvipr'

with a recent install of pyvipr and running in JupyterLab.

I'm working in a conda environment on Windows.

Additional Context

OS: Windows 11
Python 3.11.3
JupyterLab 4.0.6
pyvipr 1.0.7
nodejs 20.8.0 (conda-forge)
