Use Root wihtin Sage notebook

ROOT
1

Hi,

I would like to use some of the root functions within a sage notebook.
I have found an older thread on this and tried to make it work.
As i use:

import sys
sys.path.append('path/to/root/lib')
import ROOT

it seems to work, at least I don’t get an error message.
Then I simply try to create a canvas:

c = ROOT.TCanvas("c", "c", 800, 600)

which fails with the error message:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "_sage_input_7.py", line 10, in <module>
    exec compile(u'open("___code___.py","w").write("# -*- coding: utf-8 -*-\\n" + _support_.preparse_worksheet_cell(base64.b64decode("YyA9IFJPT1QuVENhbnZhcygibXlDYW52YXNOYW1lIiwiVGhlIENhbnZhcyBUaXRsZSIsODAwLDYwMCk="),globals())+"\\n"); execfile(os.path.abspath("___code___.py"))

  File "", line 1, in <module>

    takes at least 6 arguments (4 given)
  TCanvas::TCanvas(const char* name, int ww, int wh, int winid) =>
    could not convert argument 2

Any idea what I am doing wrong or missing?

Best regards

Hi Jo,

sagemath notebooks are not supported.
Jupyter technology has been integrated with ROOT though, starting from release 6.06.

Hi Danilo,

thanks for your reply, I have read about that and thought it might also work with other notebooks based on python.

Cheers

Hi Jo,

not at the moment.
What is possible with the present version of ROOT is to use in the context of Jupyter a ROOT Kernel to directly type in the cells C++ code or ROOT as a Python module in a Python notebook.
