Whenever I open a jupyter notebook in Sage 7.5.1 (sage -n jupyter), issuing a magic command
%attach myfile.py
or an inline attachcommand
attach("muyfile.py")
results in an error:
UsageError: Invalid GUI request 'sage', valid ones are:['osx', 'qt4', 'qt5', 'nbagg', None, 'gtk', 'gtk3', 'notebook', 'tk', 'inline', 'wx', 'qt']
I found this error in sagemath 7.5.1, but it is not present in sagemath 7.2. The magic %load, however, works.
Any workarounds? (besides changing %attach to %load, I mean.)
