Help with selection of grid2op version for the code I have

[MuhaoGuo]

I have a grid2op code that I want to run. I was told to try grid2op 1.0.0 version for the code I was given. However, when I run the following line of code env = make("rte_case14_realistic", param=param), I got the following error trace

Can you help me find the grid2op version that would not give me this error without making any changes to the code I have? Thank you very much in advance!

Hello

First, don't use grid2op version as old as this. We don't support it anymore. Are you sure it does not work with latest version? Have you tried the grid2op "compatibility" mode ?

Second, this sounds more like a pandapower issue: your pandapower version is unable to read the file from the environment which is more or less normal because we never really tested (nor used) this environment :-/ Ça you use the l2rpn_case14_sandbox by any chance?

Also to be more constructive : what are you trying to do? It's probably easier done with most recent versions.

Hi,

Has your problem been fixed ? (I'll close the issue if it has been)
