Cannot import plugins on Ubuntu

[cwk]

Hi all,

I am running vapoursynth R36 on Ubuntu 16.04. I am seeing errors in loading non-core plugins:

vspipe --y4m 1.vpy encode.avi
Script evaluation failed:
Python exception: No module named 'adjust'
Traceback (most recent call last):
File "src/cython/vapoursynth.pyx", line 1712, in vapoursynth.vpy_evaluateScript (src/cython/vapoursynth.c:34991)
File "1.vpy", line 4, in <module>
import adjust
ImportError: No module named 'adjust'

Script:
import vapoursynth as vs
import adjust

core = vs.get_core()

vid = core.ffms2.Source(source='VTS_02_1.VOB')
vid2 = core.yadifmod.Yadifmod(vid, core.nnedi3.nnedi3(vid, field=3), order=1, mode=3)
#vid3 = core.std.Tweak(vid2, sat=1.4)
vid2.set_output()

I believe the plugins are in the correct place:

Am I doing something obviously wrong? Any insight you code provide would be appreciated.

This might help.

Definitively create a bug report at your package maintainer's github repo, this is a long standing bug for your distro. I mean, why the need to rename module's names? He could just move them inside a directory if he is so obsessed with order.

[cwk]

Thank you for the quick responses.

Yes, it was the hyphen in the plugin names that was breaking the import process. I've removed the vs- prefix from the plugins, as that yields a slightly more intuitive script:

vid5 = vs_adjust.Tweak(vid4, sat=1.3, cont=1.15)

vs

vid5 = adjust.Tweak(vid4, sat=1.3, cont=1.15)

I've also filed an issue here:

In the meantime I updated my dockerfile to rename the plugins when building:

RUN cd /usr/lib/python3/dist-packages && \
rename 's/vs-//' vs-*.py

[djcj]

@Are_: I'm not "obsessed" with order, I wanted to avoid issues in case other packages would install scripts with the same name. I had already fixed this by moving the stuff into a sub-directory but I forgot to update the PPA.

[cwk]

@djcj, thank you for the fast work. Is the ppa updated? If so, I would be happy to test.

[cwk]

@djcj, The package now doesn't install the plugins, or if it does, to the wrong directory:

# apt-get install vapoursynth-extra-plugins
Reading package lists... Done
Building dependency tree

vapoursynth-extra-plugins is already the newest version (20170110-1~xenial).
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.

I'm expecting the the plugins to show up here:

[cwk]

False alarm. The plugins are installed by the ppa, but to a different directory:

# find . -name 'adjust*'
./usr/share/vsscripts/adjust.py

I needed to adjust my PYTHONPATH environmental variable to include this path, and things are working.

Thanks again for the fast turnaround.
