The "Drop our use of namespace packages" spec explains why.

Re: [openstack-dev] [Neutron] ImportError: No module named neutron_lib

2017-03-08 Thread Sam 
I found this:

from oslo_config import ...
from oslo_db import ...
from neutron_lib import ...

actually these libraries is oslo.config, oslo.db, neutron.lib

Why not write like this: from oslo.config import ... ?

And for local package, its: from neutron.api import ...

WHY ?

Make sure you're installing with upper-constratints otehrwise you'll get
components that rely on features for newer releases

Assuming you're installing with pip something like[1]

wget 'http://tarballs.openstack.org/neutron/neutron-8.4.0-py2.py3-none-any.whl'
wget 
'http://git.openstack.org/cgit/openstack/requirements/plain/upper-constraints.txt?h=stable/mitaka'

pip install -c upper-constratints.txt ./neutron-8.4.0-py2.py3-none-any.whl

Should get you a stable/mitaka neutron with appropriate versions of all
libraries in use.

Yours Tony.

[1] You may be able to pass the URLs directly to pip but I haven't tested that

Yes, that is one of the ways that neutron-lib is packaged.  The 'upstream'
is at http://git.openstack.org/cgit/openstack/neutron-lib.

Exactly how are you using the Neutron code?  If you are starting from a git
clone and running Neutron code/tests on your own machine, you should
normally do that within one of the virtual environments that is set up by
'tox', and that process would pull in the neutron-lib code for you.

Best wishes,
 Neil

[openstack-dev] [Neutron] ImportError: No module named neutron_lib

2017-03-06 Thread Sam 
Hi,

I'm using neutron mitaka version, I found lots of files include this:
"from neutron_lib import exceptions as e"
But I don't find where is neutron_lib, and I got error as "ImportError: No
module named neutron_lib"

Is there some error?
