I can also use
%load_ext sage
to use Sage commands.
If I'm in a Sage worksheet, is there a package to load so that I can use markdown commands? Or alternatively, is there a way I can get two different colors of comments with a hashtag (#)?ElkTue, 07 Feb 2017 18:15:51 +0100https://ask.sagemath.org/question/36478/IP-Notebooks and extensions, Sage versus Sage Cloudhttps://ask.sagemath.org/question/23226/ip-notebooks-and-extensions-sage-versus-sage-cloud/ In Sage Math Cloud I can open an IP:Notebook, execute
%load_ext sage
and Sage runs whithin the IP:Notebook.
Trying to do the same with my local IPython fails. I get an ImportError:
../IPython/core/extensions.py in load_extension(self, module_str)
96 if module_str not in sys.modules:
97 with prepended_to_syspath(self.ipython_extension_dir):
---> 98 __import__(module_str)
99 mod = sys.modules[module_str]
100 if self._call_load_ipython_extension(mod):
ImportError: No module named 'sage'
Where can I get this module 'sage'? Or is it private to SMC?
-- **EDIT** -- [26-11-2014]
According to slelievre below:
"In Sage 6.4.beta6 or later, $ sage --notebook=ipython should also work."
In fact I get:
sage --notebook=ipython

Does "%load_ext sage" not invoke the Sage preparser?

integrate(x^2,x)
I get
1/3*x^3
as desired.
<br>
However, if I start sage in IPython's notebook with **sage -ipython notebook** and type the same thing I get
NameError: name 'integrate' is not defined
Trying to fix this by defining some prerequisites
from sage.all import *
,var x
I now get
RuntimeError: Use ** for exponentiation, not '^', which means xor
in Python, and has the wrong precedence.
<br>
**In other words, it is clear that *sage -ipython notebook* does not provide the same environment as *sage*.**
<h1>How can I fix this? I just want an IPython notebook that works like my sage command line.</h1>testtest2Wed, 08 Jan 2014 07:58:50 +0100https://ask.sagemath.org/question/10894/is it possible to run a sage in ipython notebook?https://ask.sagemath.org/question/10666/is-it-possible-to-run-a-sage-in-ipython-notebook/I want run some sage commands in ipython notebook (in cloud.sagemath.com), is it possible?
And the same question but local, i.e., using ipython notebook via canopy and insert some command of sage.
