It seems that there is no solution to my problem but I am still hoping. I installed the Windows native version of Sagemath and every try to use plot3d (i.e. var('y') plot3d( 4xexp(-x^2-y^2), (x,-2,2), (y,-2,2))) runs into the following error:
/opt/sagemath-8.0/local/lib/python2.7/site-packages/sage/repl/rich_output/display_manager.py:590: RichReprWarning: Exception in _rich_repr_ while displaying object: Jmol failed to create file '/dot_sage/temp/Sandman/16196/dir_oUJsU7/preview.png', see '/dot_sage/temp/Sandman/16196/tmp_9jJjSY.txt' for details RichReprWarning,
Is anybody out there who can help to fix that Sagemath bug?
Thanks for your help!
