Revision history [back]
 | 1 | initial version |
I can reproduce with - SageMath 9.8 from conda-forge in Ubuntu 22.04. - Firefox installed as a "snap"
Arguably the problem is from Firefox rather than SageMath, as
- SageMath saves the image to some html file in /tmp
- Firefox installed as a snap refuses to open files in /tmp
Two ways around this
- either reinstall Firefox not as a snap, which might help according to:
- or use a workaround: manually save 3d graphics to html file, then open that file in a browser.
Example.
My Firefox is installed using apt install firefox, which installed it as a "snap":
$ dpkg-query --list firefox

Define 3d plot:
sage: p = plot3d(x*y^3, (-1, 1), (-1, 1))
Try to view:
sage: p
For me this launches a Firefox tab which tries to access a temporary file and complains:
File not found
Firefox can’t find the file at /tmp/tmp58e2me0a/tmp_68ciixtz.html.
- Check the file name for capitalization or other typing errors.
- Check to see if the file was moved, renamed or deleted.
The problem seems to be that Firefox installed as a "snap"
refuses to open local files in /tmp.
Save the plot to an html file and open that file:
sage: p.save("myplot.html")
sage: !open myplot.html
That works well for me.

Arguably the problem is from Firefox rather than SageMath, as
What happens is:
- SageMath saves the image to some html file in
/tmp then asks your browser to open it - Firefox installed as a snap
refusesis set not to open files in/tmp
Two Three ways around thisthis (including the one suggested by @John Palmieri):
- either reinstall Firefox not as a
snap,"snap", which mighthelp according to:help, see: - or
use a workaround:run Sage with theTMPDIRenvironment variable set to some directory inside your home directory - or, as a workaround, manually save 3d graphics to html file, then open
that file in a browser.obtained file in browser

Version of Sage and Python:Here is what happens in that situation.

For me this launches a Firefox tab which tries to access a temporary file and complains:
File not found
Firefox can’t find the file at /tmp/tmp58e2me0a/tmp_68ciixtz.html.
- Check the file name for capitalization or other typing errors.
- Check to see if the file was moved, renamed or deleted.
The problem seems to be is that Firefox installed as a "snap"
refuses "snap" is set not to open local files in /tmp.
Save Things work if Sage starts with TMPDIR set to a subdirectory of the user's home directory.
I created a tmp directory in my home directory:
$ mkdir -p $HOME/tmp
Then things work if I start Sage with this command:
$ TMPDIR=$HOME/tmp sage
or with these two commands:
$ export TMPDIR=$HOME/tmp
$ sage
The "export" command can be included in a file that is run each time a shell is started.
For example,~/.bashrc if using bash, or ~/.zshrc if using zsh.
If Sage was started without setting TMPDIR, we can save the plot to an html file and open that file:
sage: p.save("myplot.html")
sage: !open myplot.html
That works well for me.
