Meshroom: pyside setup, setup.py, error in file?

Created on 30 May 2018  路  19Comments  路  Source: alicevision/meshroom

I am trying to build meshroom following the instruction. When I run:

git clone --recursive --branch 5.9 https://codereview.qt-project.org/pyside/pyside-setup

cd pyside-setup

python setup.py --ignore-git install --cmake="C:/Program Files/CMake/bin/cmake.exe" --qmake="C:/Qt/5.10.0/winrt_x64_msvc2017/bin/qmake.exe"

it gives me the following error:

  File "setup.py", line 41, in <module>
    from ez_setup import use_setuptools
  File "E:\AliceVision\meshroom\ThirdParty\pyside-setup\ez_setup.py", line 227

Qt now provides wheels for PySide2, so you don't have to build it yourself ! :)
We're currently documenting this and fixing issues with the latest version of PySide on the dev_setup branch. It's about to be merged in develop, so you should probably checkout this one in the meantime.
PySide installation has been updated in the INSTALL.md there.

pip install --index-url=http://download.qt.io/snapshots/ci/pyside/5.11/latest/ pyside2 --trusted-host download.qt.io

Strange, that gives me: Fatal error in launcher: Unable to create process using '"'

python 2.7.15 fixes this.

But running:

gives me:

Your current path is not automatically added to the PYTHONPATH.

set PYTHONPATH=%CD%
python meshroom\ui

You are good!
simpleFarm is just a warning (even if it's unfortunately written "error").

ok great! I don't see a ui though, do i need to run something else?

antithing picture antithing on 30 May 2018

Cancel that, I ran it again and it opened. Thanks again for your time.

Sorry! One more... On dragging an image into the UI

IOError: [Errno 2] No such file or directory: 'c:/users/bsharp/appdata/local/temp/tmpkiyqag/CameraInit/fdba592891e8db45e3af8f93b1a59e1470b45d69/cameraInit.sfm'

Looks like it can't write to the cache folder, as it does not exist. Can i change the cache dir?

antithing picture antithing on 30 May 2018

Do you have the full log to see if it's the only error you get ? It may have failed to create this file for another reason.
Could you try to save your project somewhere (File > Save As...) ? The cache folder will be created next to the project file.

Created new project, saved as. Drag an image in:

AliceVision's binaries must be in your PATH when using Meshroom. Could you try adding the (release) build folder to your PATH before launching meshroom: set PATH=path\to\alicevision\build;%PATH% ?

yann-lty picture yann-lty on 30 May 2018

AH of course! That did it. Thank you again.

I'm having a really hard time getting PySide2 / Qt to work correctly from meshroom, so I hope anyone who can get this to work can share a bit of info about their setup. Specifically, I am leaning heavily on vcpkg to get all the deps for AliceVision (including various that use Qt, such as opencv), however vcpkg's Qt is too old for the PySide2 wheel, so I've also installed Qt 5.10 using the vendor's installer.

Is it possible that that's all you need to read to know that I'm doomed? Do I need to build all the AliceVision deps using the exact same Qt as is used by PySide2? Alternatively, should I give up on the PySide2 wheel and attempt to build my own PySide2 against the Qt 5.9 provided by vcpkg?

After deleting all .pyc files from the meshroom project, attempts to start UI (with python meshroom/ui) fail like this (detailed log below):

Cannot mix incompatible Qt library (version 0x50a00) with this library (version 0x50b00)

I'm currently using Python via Anaconda (I started down the path of building my own python2, but .... that's just a dumb rats nest of fighting with the build environment, so I'm hoping I don't need to do that)

Sample QML projects work when they are built and run via QtCreator, so I think the 5.10 installation is self-consistent. Also, a very basic PySide2 / qml example (from the official docs) seems to work when called from the same python I'm using to (try to) run meshroom.

Here's a verbose log of trying to start meshroom's UI, inside of a virtualenv called meshroom.

EDIT: Updating the system-wide installation of Qt to 5.11 resolved the error! I have UI now!

Maybe I'm just an idiot and the PySide2 wheel actually has enough Qt that I didn't need to install it separately. The install doc says "Pyside2 (for Qt >= 5.10)", which to me implies "this works with Qt versions greater than or equal to 5.10", so... I'm confused :)

In any case, I feel like this is probably the source of the version conflict...

PS C:\Users\andre> (Get-Item G:\libs\qt5\5.10.0\msvc2015_64\bin\Qt5Qml.dll).VersionInfo

PS C:\Users\andre> (Get-Item C:\Users\andre\Anaconda3\envs\meshroom\Lib\site-packages\PySide2\Qt5Qml.dll).VersionInfo

ProductVersion   FileVersion      FileName

If I simple move aside my system-wide installation of Qt 5.10 (by renaming the top-level directory), then I'm back to plugin cannot be loaded for module "QtQuick.Controls". I'll try upgrading the system-wide installation to 5.11.

PySide wheels are indeed enough. They come with needed Qt's files and binaries. You don't have to install Qt separately. And none of mandatory AliceVision dependencies requires Qt. Even (optional) OpenCV can be built without Qt using vcpkg. Using the pip command to install PySide2 (based on Qt 5.11) stated above and in the docs is sufficient. If documentation is confusing, we should probably update it.

@yann-lty Thanks for the confirmation. I guess the thing to note is that if there's another Qt installation (that's in PATH), it probably needs to be the same version as what PySide2 is bundling. I never did pinpoint exactly how my pre-existing (non-PySide2) Qt is getting pulled in at runtime, but I'm fairly sure that it's happening, at least on my machine.

Update: using Process Explorer, I got a list of all the Qt-related libraries loaded by meshroom's host python process, and sure enough they are coming from two distinct locations: the Anaconda virtualenv that has PySide2, and also my system-wide Qt installation.
