ImportError: cannot import name 'CubicSpline' about easyeffects

[wwmm]

Hi, the latest PulseEffects also needs the packages python-numpy and python-scipy(this is the name in Arch Linux it may be other in Neon). CubicSpline module was implemented in scipy 0.18. So older scipy versions will not work unless someone have backported this module

[wwmm]

At least in Arch numpy and scipy are offered for python 2 and 3 in different packages. Make sure you have the packages for python 3 installed

[kevinsmia1939]

I download pulseeffects version 1.4.0 instead. I don't know what I mess up.

[wwmm]

The lines self.audio_src.set_property('client-name', 'PulseEffects') and AttributeError: 'NoneType' object has no attribute 'set_property' are telling you do not have the gstreamer plugin pulsesrc installed. At least in Arch this plugin is in the package gst-plugins-good

[kevinsmia1939]

I fix it, I have already install gstreamer-pulgins-good, what I need is gstreamer1.0-pulseaudio. Also I need to fiddle with pavucontrol to make it work. Also did you remove the equalizer presets?

[wwmm]

I had to remove most of them when I moved to a 15 bands equalizer. I do not know how to make presets for music styles like rock, pop, techno, etc. If someone that knows how to make these presets sends me the values for 15 bands I will add them to PulseEffects.

[DroWnThePoor]

Having a similar problem, but contains more errors than OP.
I've done the actual install not just running the program

Any ideas? Should I open a separate issue?

[wwmm]

Hi, it is the same problem. Scipy is not installed or is installed for python2 and not python 3 or it is installed for python 3 but its version is below 0.18. The module CubicSpline is not present in older scipy versions.

[DroWnThePoor]

Okay thanks. Found out Ubuntu 16.04s scipy repo only goes to .17 so I'll have to find a way to get it elsewhere. Any clues? I have pip and easy_install.

[dx9s]

@DroWnThePoor you found a solution to getting the correct/good enough Scipy on Ubuntu 16.04 ?

[dx9s]

This seems to have worked for me:

$ sudo apt-get install python3-pip
$ pip3 install numpy scipy
$ pip3 install --upgrade pip # (this is optional but I did it)

GSETTINGS_SCHEMA_DIR=share/glib-2.0/schemas/ ./pulseeffects

and it is working (after the usual 'glib-compile-schemas share/glib-2.0/schemas/')

[dx9s]

Update, it mostly works. The graph (250 point RTA) isn't working.

~/src/pulseeffects$ git status
HEAD detached at v2.1.2
nothing to commit, working directory clean

Probably another problem elsewhere -- the audio is working tho.

[wwmm]

@dx9s when you run PulseEffects from the command line is there any error printed?

[dx9s]

Yes but I don't remember the details, I can collect them -- not sure where a safe place to dump lots of text is ?! Pasting inline?

[dx9s]

where pulseeffects is in my local bin as:
( cd /home/dx9s/src/pulseeffects ; GSETTINGS_SCHEMA_DIR=share/glib-2.0/schemas/ ./pulseeffects )

[wwmm]

The error TypeError: unknown type GstValueList is happening because only Gstreamer 1.12 or higher has this type defined.

[dx9s]

I figured it was Gstream related (version) I just wasn't overly concerned as it only effected the visuals.

[LeCalicot]

I also have trouble to get it running on Ubuntu 16.04
I couldn't install the 0.18 version of scipy and I have the same error with CubicSpline.

Any suggestion?

Edit: It was installed with apt-get. I totally removed scipy (and numpy) and reinstalled them with pip.

[wwmm]

As there is nothing I can do about missing dependencies in ubuntu I will close this issue.
