Colab problem

[dnbl1960]

Summary
"An EPANET simulation cannot be run from Colab, apparently after the new version of WNTR

The problem arises when I attempt to perform a simulation with EPANET from WNTR, for example
wn = wntr.network.WaterNetworkModel(inp_file):
sim = wntr.sim.EpanetSimulator(wn)
results = sim.run_sim()
The following error appears:
OSError: /usr/local/lib/python3.11/dist-packages/wntr/epanet/libepanet/linux-x64/libepanet22.so: cannot open shared object file: No such file or directory
Thanks!

Hi @dnbl1960, thanks for bringing this to our attention. We have identified the problem (see #467) and a fix should be rolled out soon.

Good Morning, I just tried running a simulation with Epanet from Colab, and it gives the same error: "OSError: /usr/local/lib/python3.11/dist-packages/wntr/epanet/libepanet/linux-x64/libepanet22.so: cannot open shared object file: No such file or directory" Thanks!

Good Morning, I have the identical issue, error "
OSError: /usr/local/lib/python3.11/dist-packages/wntr/epanet/libepanet/linux-x64/libepanet22.so: cannot open shared object file: No such file or directory" occurs when I try to run a simulation with Epanet from Colab.

@kmilenkovic @dnbl1960, while we are working on the fix I recommend you proceed by installing an old version of wntr. Something like

!pip install wntr==1.2.0

in Colab should suffice.

Problem solved! Thank you!
