2019-04-14 14:16:06 +0200	asked a question	loaded file not found I am trying to load a python script into sage notebook, with commands load('file.py'), and attach('file.py'). But I am getting the error: `IOError: did not find file` The file is there! I am using sage 8.6 on Windows 10. `sage: load('C:\\Program Files (x86)\\MyJournal\\Images\\functions.py')` UPDATE Sage loads the file from my home directory. I seems that Sage just does not have access to Program Files directory. --------------------------------------------------------------------------- IOError Traceback (most recent call last) <ipython-input-104-057b25088154> in <module>() ----> 1 load('C:\\Program Files (x86)\\MyJournal\\Images\\functions.py') /opt/sagemath-8.6/local/lib/python2.7/site-packages/sage/misc/persist.pyx in sage.misc.persist.load (build/cythonized/sage/misc/persist.c:2470)() 134 135 if sage.repl.load.is_loadable_filename(filename): --> 136 sage.repl.load.load(filename, globals()) 137 return 138 /opt/sagemath-8.6/local/lib/python2.7/site-packages/sage/repl/load.py in load(filename, globals, attach) 233 break 234 else: --> 235 raise IOError('did not find file %r to load or attach' % filename) 236 237 ext = os.path.splitext(fpath)[1].lower() IOError: did not find file 'C:\\Program Files (x86)\\MyJournal\\Images\\functions.py' to load or attach

2019-04-14 02:23:24 +0200	asked a question	3d graphics not displayed I am new to Sage. I use SageMath 8.6 on Windows 10. 2D plotting works, but not 3d. For example this produced no graphics but just the: `𝙶𝚛𝚊𝚙𝚑𝚒𝚌𝚜𝟹𝚍𝙾𝚋𝚓𝚎𝚌𝚝` `sage: x, y = var('x,y') sage: g = plot3d(x^2 + y^2, (x,-2,2), (y,-2,2)) sage: show(g) 𝙶𝚛𝚊𝚙𝚑𝚒𝚌𝚜𝟹𝚍𝙾𝚋𝚓𝚎𝚌𝚝` I use Chrome. With the suggested option: `sage: show(g,figsize=8, viewer="threejs", frame=False,axes=True)` it works now! It works also with: `sage: show(g,figsize=8, viewer="threejs", axes=True)` And with: `sage: show(g,figsize=8, viewer="threejs")` It looks like viewer option should be there for 3D to work on windows 10 with Chrome. SageMath is great! With Python it is much more friendlier than Mathematica.
