Cant run BiG-Scape after installation

[Dmente92]

Dear all,

I have installed BiG-Scape following the wiki. Sadly, when I execute the command 'python bigscape.py --version', I just get the following error:

Traceback (most recent call last):
File "bigscape.py", line 63, in

ImportError: libgfortran.so.3: cannot open shared object file: No such file or directory

Any idea how to solve this issue. Thanks

Hi Daniel

What's your version of scikit-learn? Versions higher than 0.19.2 have created problems in the past

[Dmente92]

Hi @jorgecnavarrom , my version of scikit-learn is precisely 0.19.2

[Dmente92]

Hi @jorgecnavarrom , I managed to solve the issue. I just uninstalled scikit-learn 0.19.2 from the conda environment and installed the v0.19.1. Everything is running fine for now. Thanks

Hi

I followed the conda installation instruction from the wiki but I faced the same issue. I tried reinstalling with scikit-learn 0.19.1 but did not solved the issue.

I have apparently solved the issue (I still needs to test) by installing libgfortran 3.0.0 as described here: ContinuumIO/anaconda-issues#686 (comment)
