cannot find vtkplotter package

[kohanyirobert]

I receive the following error on Windows 10 and Ubuntu 18.04 as well after I import a score and click on 3D player in the GUI.

VirtualKeyboard: cannot find vtkplotter package. Not installed?
Try:
(sudo) pip install --upgrade vtkplotter

Any idea?

Hi, thanks for reporting, indeed the 3D functionality is faulty at the moment, I will release a new version in the next days, unfortunately I didn't have much spare time to dedicate to this lately! Where you able to generate the xml document with the fingering labels?

[kohanyirobert]

Yep both worked (alas, this was my first use of the program - I was mainly interested in visually seeing the fingering).

[marcomusy]

I just pushed the version that I had in my local, so if you want to try it out, type: pip install -U git+https://github.com/marcomusy/pianoplayer.git

The GUI now shows, but I get this instead

Input File is  C:/Users/rkohanyi/Work/git/pianoplayer/scores/bach_invention4.xml

I've tried with a simpler score as well to no avail. Should this be turned into another issue?

[marcomusy]

Are you sure you pressed GENERATE before 3D Player ?

[kohanyirobert]

You're right, didn't think I'd need to do that, nevermind, my fault. However I get this now after I hit space the very first time in the Tk window (the hands and all are showing).

[marcomusy]

oh, looks like numpy's python 3.8 is more strict on argument passing.. Try again: pip install -U git+https://github.com/marcomusy/pianoplayer.git

You may also try from command line something like: pianoplayer scores\bach_invention4.xml -n10 -vz

Thanks for your patience in debugging this

This seems to work, although when I exit the keyboard window I receive the error below.

Also, the whole experience is choppy on my end, after hitting space there's a 1-2 seconds delay between finger changes and the sounds are continuously kept on which is horrendous, I jumped when I started the playback without the -z flag :)

yes - unfortunately I could not find a decent library to generate sound in python which is quite surprising :( the lag is due to the fact that it's trying to play the note with the prescribed duration but it fails... I 'll try to fix that.

The awful core dump is pretty weird, I have no idea why that happens, maybe your hardware doesnt support 3d textures.

Probably, not a big deal, it works to an extent.

Sure. I'm closing this issue as my initial problem is solved now. Thanks for the cooperation.
