OS: Ubuntu

installed sage with

sudo apt install sagemath

tried to run an example with

sage -python example1.py

Got error

Have you seen this error before? Any suggestions how to fix it?

sage --version
SageMath version 8.1, Release Date: 2017-12-07

Die Readme auf dem Branch fix-sagemath-version sagt

To run the script use: python3 example*.py

aber da bekomme ich einen ModuleNotFoundError:

python3 example1.py
ModuleNotFoundError: No module named 'sage'

Auf dem neuen Branch hast Du nur Tabs gegen Spaces getauscht, oder? Bekomme dieselben Fehler wie zuvor:

git checkout fix-sagemath-version
python3 example1.py
ModuleNotFoundError: No module named 'sage'
sage -python example1.py
TypeError: type.__new__(metaclass) is not safe, use sage.misc.classcall_metaclass.ClasscallMetaclass.__new__()

Ich kann das Docker Image hochfahren. Da läuft Sage 9.0:

docker build -t rschwieger:classifier .
docker run -v ~/IdeaProjects/Classifier-construction-in-Boolean-Networks-using-algebraic-methods:/media -it rschwieger:classifier
root@187ff98181e8:/media# sage --version
SageMath version 9.0, Release Date: 2020-01-01
exit

Das example1.py läuft im Docker Image ohne Fehler durch. Hier die Ergebnisse pro Branch / Befehl.

Auf dem fix-sagemath-version Branch

git checkout fix-sagemath-version
docker run -v ~/IdeaProjects/Classifier-construction-in-Boolean-Networks-using-algebraic-methods:/media -it rschwieger:classifier
cd media
python3 example1.py
...

sage -python example1.py

exit

Auf dem Master Branch:

git checkout master
docker run -v ~/IdeaProjects/Classifier-construction-in-Boolean-Networks-using-algebraic-methods:/media -it rschwieger:classifier
cd media
python3 example1.py

Ich habe jetzt den Fix-Branch in den master gemergt, da im Docker die neuere sage Version installiert ist. Und ja, ich hatte im Dockercontainer Probleme mit den Tabs. Deswegen hatte ich die nochmal geändert.
