Makehuman not working in arch linux - numpy 1.13.1

Postby artistafrustrado » Tue Sep 19, 2017 2:26 am

After a system upgrade a few months ago, makehuman stoped exporting mhx2. At first I thought it was a problem with the mhx2 plugin but when I tested exporting to other formats, I got the same error.

As far as I can tell it has something to do with numpy but I have no idea how to fix it.

Write MHX2 file /home/artista/makehuman/v1/exports/teste.mhx2

Do you happen to know which version of numpy was the last it worked with?

Anyway, it sounds like it is related to this bug: http://bugtracker.makehumancommunity.org/issues/1184

Can you edit core/module3d.py and insert a few debug lines? The relevant block (around line 311) now reads:

Code: Select all
    # Filter out and remap unused UVs
    fuvs = self.fuvs[self.face_mask]
    uv_idx = np.unique(fuvs.reshape(-1))
    inverse_uv_idx = - np.ones(self.texco.shape[0], dtype=np.int32)
    inverse_uv_idx[uv_idx] = np.arange(self.texco.shape[0], dtype=np.int32)
    for i in xrange(self.vertsPerPrimitive):
        fuvs[:,i] = inverse_uv_idx[fuvs[:,i]]


Can you change it so that it reads

Code: Select all
    # Filter out and remap unused UVs
    fuvs = self.fuvs[self.face_mask]
    uv_idx = np.unique(fuvs.reshape(-1))
    print "\n\nTEXCO\n\n\n----"   # NEW LINE
    print self.texco.shape[0]     # NEW LINE
    print "----\n\n";             # NEW LINE
    inverse_uv_idx = - np.ones(self.texco.shape[0], dtype=np.int32)
    inverse_uv_idx[uv_idx] = np.arange(self.texco.shape[0], dtype=np.int32)
    for i in xrange(self.vertsPerPrimitive):
        fuvs[:,i] = inverse_uv_idx[fuvs[:,i]]


... start MH, add the clothing piece "female elegant suit", try to export via MHX2, and post the relevant sections of the console output (ie where it says "TEXCO") here?

Also, assuming this crashes as expected, can you retry the procedure, but also uncheck "hide faces under clothes" on the "clothes" tab, as well as set eyes to "none" on the "eyes" tab, and see if that makes anything different when exporting?

This is what I got.

Write MHX2 file /home/artista/makehuman/v1/exports/debug.mhx2


TEXCO

Ok, right now I have no other solution than downgrading numpy to 1.11.0, which is known to be working.

I've got the same problem also running Arch. I tried putting the numpy 1.11 module in the plugin folder and now I get this error instead.

I don't really know what I'm doing but I'm happy to help debug this if I can.

Numpy is not repeat not a plug-in it is a compiled module for Python so no surprise that putting it in the plug-in folder did not work you have to replace numpy 1.13.1 with numpy 1.11 which is a downgrade of a package that arch upgraded automatically not sure how one goes about this on arch but it will involve working in the system level files so root privileges are required for any changes you make.

Enjoy the Choice :)

I understand that numpy is not a makehuman plugin. I actually use numpy pretty frequently, which is why I don't want to downgrade my system module. Yes, maybe I can set up a virtual environment to run an older version of numpy just for makehuman, but I'd have to figure out how to do that, and I already have a lot of things to work on. I havn't yet needed to use virtual environments for anything else.

I just thought that if I put the source code for numpy 1.11.0 in the same folder as the MHX2 exporter plugin then it would use that instead of the system numpy module which is a later version, and it appears to do just that. At least that's how I interpreted the stacktrace, but it looks like it couldn't import it for some reason though. Like I said I don't really know what I'm doing here.

Ok apparently this plugin uses python 3? I discovered that my numpy 1.11.0 didn't work because it was the python 2.7 version. It's weird because the shell inside makehuman says it's 2.7 but apparently the plugin is not 2.7?

However this did not help solve the problem, as I'm just right back to the original shape mismatch error. It doesn't look like a problem with numpy, or at least using numpy 1.11.0 for python 3.5 didn't help. It might be a problem with the AUR version of makehuman. There is a bug complaint there. Hopefully it gets fixed.

Yes Python 2.7 is the right version for makehuman's stable version we are working on porting to Python 3 and updating from qt4 to qt5 as qt4 no longer has support but that branch is not yet ready for release.Maybe the AUR packager has miss read the proper dependencies for makehuman and assumed that we are using Python 3.

Enjoy the Choice :)
