Python module numpy missing on clean PPA install.

[mlampert]

I installed a pristine Ubuntu vm (16.04.1 LTS) and immediately added freecad-daily PPA to it and installed it.

The moment I try to select the Path workbench I get a popup saying "No module named numpy" (all other WBs seem OK). Is this a known issue?

Other than that it works like a charm! Great work guys

Thanks mlabert! It seems FreeCAD has a hard runtime dependency, not addressed, to python-numpy now. Can you try the FEM WB in the same experiment? We need a doc update.

Code: Select all

sudo apt-get install python-numpy

should fix it.
EDIT: @chrisb, what's the situation on OSX?

[mlampert]

I did start the FEM WB and it was good - is there anything I should run in the WB ?

[chrisb]

I can select Path WB and FEM WB without problems. Tiny test in PathWB worked, no idea how or what to test in FEM WB.

OS: Mac OS X
Version: 0.17.8443 (Git)
OCC version: 7.0.0

I'm not sure how to test I did discern this

It looks like PartDisign/WizardShaft has a try/except. I didn't check the others. I'll add python-numpy as a runtime dependency for the PPA, unless there are objections?

Slightly off topic. Can someone explain the OSX/Python environment. I don't see this dependency in Travis.

[chrisb]

I am not familiar with the python situation on OSX but numpy seems to be shipped with FreeCAD.
I can do the following in FreeCAD's python console and the result shows the shipped path:

Code: Select all

import numpy
>>> numpy.__path__
['/Users/cb/freeCAD/FreeCADDaily.app/Contents/lib/python2.7/site-packages/numpy']

Thanks again chrisb! I think we need bblacey to explain, at least to me

Hello sgrogan,

This is probably off-topic, but I just noticed tonight that when doing File --> Open after a fresh launch of the freecad-daily package, it always opens in the /usr/lib/freecad-daily folder. It's pretty damn annoying.

Thanks, got it now, I had only looked at the travis.yaml. I'll look at the self tests. I thought all workbenches were loaded and this should have produced a failure on linux Travis.
