RuntimeError: could not open display

[worldveil]

Interesting. Try something for me - try inserting the line:

mlab.use('Agg')

just after this line and see if that changes anything.

Thanks for your quick reply :)
I did and I got:

Traceback (most recent call last):
File "go.py", line 1, in
from dejavu import Dejavu
File "/usr/src/dejavu/dejavu/init.py", line 3, in
import fingerprint
File "/usr/src/dejavu/dejavu/fingerprint.py", line 3, in
mlab.use('Agg')
AttributeError: 'module' object has no attribute 'use'

So I did:
pip install mlab
It complained about docutils not found, so I did:
pip install docutils

Then it got installed:
Successfully installed docutils
Cleaning up...

And also mlab:

pip install mlab

Requirement already satisfied (use --upgrade to upgrade): mlab in
/usr/lib/python2.6/site-packages
Cleaning up...

pip install mlab --upgrade
Requirement already up-to-date: mlab in /usr/lib/python2.6/site-packages
Cleaning up...

Again same problem:

mlab.use('Agg')
AttributeError: 'module' object has no attribute 'use'

am I missing mlab specific version or something?

I don't know anything about python yet, but I guess I'm finding the reason
why this is happening.
matplotlib was installed using yum, so I tried installing it via pip.

I got the following complaint:
Downloading/unpacking matplotlib from
https://pypi.python.org/packages/source/m/matplotlib/matplotlib-1.3.1.tar.gz#md5=789699851de28a543f3d244cf657ff68
Downloading matplotlib-1.3.1.tar.gz (42.7MB): 42.7MB downloaded
Running setup.py egg_info for package matplotlib
The required version of distribute (>=0.6.28) is not available,
and can't be installed while this script is running. Please
install a more recent version first, using
'easy_install -U distribute'.

So i updated "distribute" and then installed matplotlib (who complained
about numpy, which I upgraded using pip).
After matplotlib installed, I tried again and I also get the error message:

python go.py

Traceback (most recent call last):
File "go.py", line 1, in
from dejavu import Dejavu
File "/usr/src/dejavu/dejavu/init.py", line 3, in
import fingerprint
File "/usr/src/dejavu/dejavu/fingerprint.py", line 3, in
mlab.use('Agg')
AttributeError: 'module' object has no attribute 'use'

Sorry for posting all my procedures, but maybe this helps you help me, or
helps someone facing the same issue in the future.

Thanks again!

Sorry, my fault, I gave you bad syntax. Try these two lines in the same place:

import matplotlib
matplotlib.use('Agg')

[webudo]

Dude! You're the best!
with that 2 lines it complained about scipy (also was installed by yum).
(scipy needed "openblas-devel", then it installed ok)
Now everything runs fine :)
It also works for very short recordings (which didn't work for OpenFP,
which I was trying before your scripts).

Thanks for this great piece of software!

glad it works! I think we'll not call it an open issue for now, but perhaps a note about how to use in this way might be good in the README.md
