2019-04-14 07:16:06 -0600 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.

2019-04-13 19:23:24 -0600 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: π™Άπš›πšŠπš™πš‘πš’πšŒπšœπŸΉπšπ™Ύπš‹πš“πšŽπšŒπš

sage: x, y = var('x,y')
sage: g = plot3d(x^2 + y^2, (x,-2,2), (y,-2,2))
sage: show(g)
π™Άπš›πšŠπš™πš‘πš’πšŒπšœπŸΉπšπ™Ύπš‹πš“πšŽπšŒπš

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.
