This seems to be another bug... I created now another ticket

I'm closing this ticket now.

Seems to work now. Version: 16.08.3

I get some weird output though sometimes, I don't know if it's normal.

Steps:
a = 1 OK
b = 2

{'errorPythonBackend': , '__spec__': None, 'a': 1, '__doc__': None,
'__loader__': , 'scipy': , 'matplotlib': , 'CatchOutPythonBackend': ,
'outputPythonBackend': , '__builtins__': , '__package__': None, 'numpy': ,
'sys': , '__name__': '__main__', 'b': 2}

c = a + b OK
import numpy as np OK
dd = np.array([1,2,3]) OK

Reevaluate b = 2 then it's OK

That output appears only if I do Evaluate Worksheet, while with evaluate entry
it's fine.

Hi Simone,

I cannot reproduce this problem with the current code. Do you see
cantor_python3server running if you start python3-session? Which version of
Cantor are you using?

Regards,
Alexander

import numpy and import scipy works fine for me in a python shell run from
bash. While I still get the error from within cantor.

Hi Antonis, Hi Simone,

looks like you tried to import numpy and scipy in python3. Did you install
those modules for python3 on your system? Can you start python3 in the terminal
and do 'import numpy'? Does this work for you?

Hello, I think so; I downloaded and installed the cantor 15.11.90 version
manually, but "cantor -v" still outputs "cantor 0.6".
Sometimes I get this as result:
{'numpy': , '__package__': None, '__name__': '__main__', 'outputPythonBackend':
, '__spec__': None, 'scipy': , 'a': 10, 'sys': , '__builtins__': ,
'CatchOutPythonBackend': , '__doc__': None, 'matplotlib': , '__loader__': ,
'errorPythonBackend': }
others I get this error message:
The name org.kde.Cantor.Python3-32059 was not provided by any .service files
cantor_python3server seems to be running normally.
