Meshroom: Error when loading UI

[gnatty7]

OS: Windows
Python : 2.7.15 32-bit
PySide2 5.9
Qt: 5.10.1

Running Meshroom on develop - f7da048addcf24f73ae23a3e35a8510a82df9d45
I get an error about simpleFarm. is it not included with Meshroom?

(venv) D:\Work\apps\meshroom>python venv\Lib\site-packages\meshroom\ui\__main__.py

This is actually a warning more than an error. SimpleFarm is a python package we use to dispatch computation on our render farm, and is not directly included within Meshroom.
We plan to move this out of the default plugin path to avoid any confusing message at startup.

same here... I'm actually not sure how to start the UI:

got a bit further using pyside 5.11 instead of 5.9 but getting a segmentation fault:

If it matters, I installed PySide2 with a wheel. Maybe it's because i'm using python 3? But when I use python 2.7.15, I get:

Thanks for the precise report.
The code has been made with Python3 compatibility in mind, but we are currently working with Python2. Some incompatibilities have been introduced and need to be fixed.
We are currently using python 2.7 and Qt 5.10.

We're on vacation right now, so it will introduce a bit of delay to fix this simple issue. Sorry for that!

We plan to provide binaries, to enable more people to test and use it. We hope that Qt will provide PySide binaries in the next release.
Help on packaging would be more that welcome!

[Lhun]

Binaries would be lovely, I know the folks over at https://3dscanexpert.com/ would be interested in your project.

[fabiencastan]

@Lhun Thanks for your message. That would be awesome to get the feedback from 3dscanexpert and have discussions with them to improve the software.

Hi. Are you aware of other steps required to get meshroom to run? I've included PySide 11 from the python wheel installer. It doesn't seem to find meshroom core on either python 2.7 or 3.6. Is this a path issue? Here is the output form a clean git clone on Ubuntu 18.04:

@johnhable look at #112

Yeah, setup.py appears to be broken. I just copied the entire 'meshroom' directory in to my site-packages to run it. Obviously not ideal, but a workaround until this is addressed.

That worked for me, so now I have a meshroom directory, but can't start the UI.

@ChemicalXandco to have a working python3 code :

• dict ".iteritems()" method is now ".items()" in python3
• "basestring" keyword should be replaced by "str"

Working fine here (except my UI colors problem in both py2/py3).

I just copied the entire 'meshroom' directory in to my site-packages to run it. Obviously not ideal, but a workaround until this is addressed.

For my dev modules, I'm using .pth files : simply create a txt file with the absolute path to your "meshroom" dir inside. rename it to "whatyouwant.pth" and place it in the Lib/site-packages/ folder of your python/env installation.

Yes, you need to have meshroom accessible to python in one way or another (using pth or just by adding it to the PYTHONPATH). I updated the README in https://github.com/alicevision/meshroom/pull/120 to put it.

If you have made fixes to have python2 and python3 compatibility, a PR would be much appreciated. I don't have the setup with python3 right now to be able to make the fix and test it.

I just tested it on ubuntu 16.04 with Qt 5.11 and I also get the UI color problems.

[fabiencastan]

Made fixes on the same PR for the UI colors.

Hi fabien, UI seems to work nicely now on Windows / Pyside 5.11. thanks :)

[ChemicalXandco]

I still get /meshroom/meshroom/ui/qml/main.qml:2 module "QtQuick.Controls" version 2.3 is not installed but the python3 incompatibilities seem to have been fixed. @paulparneix, have you got PySide installed with the wheel? Anyone know how to get this working?

[fabiencastan]

You need to install pyside with Qt >= 5.10.

I added the pip command line to install PySide through the wheel in the INSTALL.md:
pip install --index-url=http://download.qt.io/snapshots/ci/pyside/5.11/latest/ pyside2 --trusted-host download.qt.io

[paulparneix]

@ChemicalXandco as Fabien said, you can use pip to directlly download the whl from qt server and install.

You can also download the wheel, cd in the .whl directory, and run "pip install name_of_the_wheel.whl"

Thank you @fabiencastan the 5.11 Pyside2 wheel solved my module "QtQuick.Controls" version 2.3 is not installed issue
(I had the 5.9 wheel installed)
