Nurbs and Silk errors

[Stou]

I installed Nurbs and Silk via Addon Manager without any error but when I tried to used it, I have errors. It look like there's some modules and variables missing.

Nurbs errors:

Running the Python command 'Nurbs_createsketchspline' failed:
Traceback (most recent call last):
File "<string>", line 271, in Activated
File "<string>", line 1, in <module>
File "C:\Users\stou9\AppData\Roaming\FreeCAD\Mod\nurbs\nurbswb\createsketchspline.py", line 9, in <module>
from scipy.signal import argrelextrema

No module named scipy.signalRunning the Python command 'Nurbs_createsketchspline' failed:
Traceback (most recent call last):
File "<string>", line 271, in Activated

File "C:\Users\stou9\AppData\Roaming\FreeCAD\Mod\nurbs\nurbswb\createsketchspline.py", line 9, in <module>
from scipy.signal import argrelextrema

Do I need to install scipy.signal package manually to get it work?

Silk errors:

Running the Python command 'ControlPoly4' failed:
Traceback (most recent call last):
File "C:\Users\stou9\AppData\Roaming\FreeCAD\Mod\Silk\ControlPoly4.py", line 42, in Activated
print mode

local variable 'mode' referenced before assignment

Do I need to set some variables somewhere?

Yes the complete scipy package is required for a lot of the methods in nurbs wb.

Thanks microelly2!

I installed WinPython 3.6.7.0 which included scipy. In GitHub, I downloaded and installed Winpython64-3.7.1.0.exe (461mb) but there's also Winpython64-3.7.1.0Zero.exe (27mb).

There's no info on what is the 3.7.1.0Zero package. Any idea? Do I need to install the Zero package too?

But only with the one I installed, it seem to work fine. But I didn't do many things with it for now, I have to read about Nerbs and Silk to lear it a little bit.

I talked to fast, I still have problem with variables in Silk.

this is a common trick to send emills a notification to read this thread.

Ok, you sent a ping to emills!

Hey @Stou would you be kind enough to edit the title of the first post of this thread from Nerbs to Nurbs please? Thanks.

[Stou]

Done! Thanks, I didn't noticed that typo.
