i installed the woodem on ubuntu18.04.1 by using the following command,

sudo add-apt-repository ppa:eudoxos/woo-daily
sudo apt-get update
sudo apt-get install python3-woo

after that, when i input the woo the following error happens,

WARN: adding /home/eudoxos/minieigen11/build to path for _minieigen11
Error importing woo._cxxInternal (--flavor= ).
Traceback (most recent call last):
  File "/usr/bin/woo", line 11, in <module>

  File "/usr/lib/python3/dist-packages/woo/__init__.py", line 147, in <module>

Hi, unfortunately it seems the packages in the PPA are broken. The best what you can do is install from the source using a script which will setup everything.

This basically does what is described in https://woodem.org/user/installation.html#compilation-from-source but in an automated manner; you will have everything installed in /usr/local and you will be able to use woo -RR to update. Ubuntu 18.04 LTS is the most tested distribution at the moment.

I cannot update the documentation directly now, being away, sorry for that.

HTH, Vaclav

When i use the typical method to install,

sudo apt-get install python3-woo 

I think it succeed, but after i input woo, it says similar problem with @MaxWiebicke,

The last image is not showing any problem...? as far as I see.

Oh, yes. It works now. I have tried a test case. So maybe the installing method using the code of python3 woo-install.py has some problems.

BTW, what does the import warning mean at the beginning? like,

ImportWarning: can't resolve package from __spec__ or __package__, falling back on __name__ and __path__
  return f(*args, **kwds)

Thanks very much.

That is a warning which actually comes from h5py which we can't do nothing about. I put warning filter around the h5py import, it should not appear anymore now.
