Hi, I am Piyush, I am new to sage, I was wondering if I could be of some help here.
I am not able to replicate this test. Is there something that I am missing? I am using Ubuntu 16.04

The problem is with Python 3. We are working hard on the transition from Python 2 to Python 3.

 Milestone changed from sage8.7 to sage8.8
Ticket retargeted after milestone closed (if you don't believe this ticket is appropriate for the Sage 8.8 release please retarget manually)
comment:5 followup: ↓ 7 Changed 6 months ago by
I may have managed to fix this error. I don't know anything about the origins of the code but the error arises in in graph_database._gen_interact_func
where it seems a string defining a function called _
is run with exec
.
I tried changing the name of the function that gets defined and ran into a different python3related bug in the sagenb
python package (maintained out of the main sage tree): it still uses xrange
in sagenb.notebook.interact
at line 1185.
I downloaded the source for that package, changed the uses of xrange
, and now the doctest passes on my machine, but the bar for passing is simply emitting a string starting and finishing with <html>
and </html>
.
I'm not sure what to suggest for this ticket, the doctest in question has something to do with the old sage notebook (sagenb). The function interactive_query
returns some html that doesn't appear do anything in jupyter, and I can't use the old notebook on python3 (an error related to Twisted). Is the old notebook formally deprecated? See #22431 and in particular the 'side remark' about the graph database explorer.
If my changes to _gen_interact_func
and the sagenb
package are wanted I can send patches, but as I can't run the notebook myself on python3 I can't even verify that it's a proper fix.

Let's ask the author of #22431 if anything was said about graph_editor
and interactive queries in graph_database
.
Also I don't know if these tools have users. If not, we may simply deprecate the parts involving sagenb
. Otherwise, someone with enough knowledge in notebooks should try to solve the issues.

As long as these changes don't break sagenb on python2, it is fine. Please send a PR on https://github.com/sagemath/sagenb (perhaps they are already fixed in the 4 most recent open PRs there.)
As to functionality to be removed, I don't know.

Thanks. We may need to think about how to deal with this in the eventual removal of sagenb, as the interact should in principle still be able to work in e.g. Jupyter notebooks, but would have to import from elsewhere. Cc:ing Jeroen as he knows a lot about how that is implemented in Jupyter and where things might need to import from now.

Now the error is in sagenb (tested over 8.8.beta6).

 Milestone sage8.8 deleted
As the Sage8.8 release milestone is pending, we should delete the sage8.8 milestone for tickets that are not actively being worked on or that still require significant work to move forward. If you feel that this ticket should be included in the next Sage release at the soonest please set its milestone to the next release milestone (sage8.9).

 Milestone set to sage8.9
comment:13 Changed 4 months ago by
If the problem is with sagenb, then can we mark the doctest as "# py2", since my understanding is that sagenb is not compatible with Python 3? That is, keep the proposed changes here, but also tag the doctest as py2 only.
comment:14 Changed 4 months ago by
can't we just skip installing sagenb on Python3?
comment:15 Changed 4 months ago by
I think that sagenb as a whole does not work with Python 3, but parts of it do, and parts are imported into the Sage library in various places. If we don't install it, some things will break. Some of the imports:
src/sage/graphs/graph_editor.py: import sagenb.notebook.interact src/sage/interacts/library.py: import sagenb.notebook.interact src/sage/interacts/debugger.py: from sagenb.notebook.interact import slider, input_box, selector
comment:16 Changed 4 months ago by
I agree with the proposal of marking this doctest as # py2
, but we should also add that there is known issue with py3, no ? This way, we don't await for a decision about sagenb.
