attach does not work in Jupyter notebooks with the sage-10.3 kernel #2916

Open williamstein opened 6 years ago

  1. Make a file code.sage with code in it.
  2. Type attach('code.sage'). There is a weird warning that has nothing to do with code.sage, but attach pretends to work.
  3. Try to use something from code.sage -- it does not work.

Note that attach works fine in Sage worksheets and sage on the command line.

Attach fails in the same way using upstream plain jupyter, so this is a Sage bug or a problem with our kernel:

Still broken, exactly in the same way, with SageMath version 8.8, Release Date: 2019-06-26.

NOTE: the load function works; it's just attach that doesn't... which is pretty serious, since that's an amazing command.

Still not working for me with SageMath version 10.4.beta8. Did anyone find a way around this?

This is an upstream bug in sage 10.3 -- https://github.com/sagemath/sage/issues/26620

Removing jupyter since this is a sage bug.
