How to use this with a portable Vapoursynth? (PyQt library location)

Selur commented 8 months ago

I'm using portable Vapoursynth R65-RC1, my python311._pth contains:

Scripts
Lib\site-packages
python311.zip
.
# Uncomment to run site.main() automatically
#import site

I installed vspreview using:

python -m pip install vspreview

which downloaded the files, and created a vspreview.exe inside the Scripts folder. When calling:

Scripts\vspreview.exe
Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main
  File "<frozen runpy>", line 88, in _run_code
  File "F:\Hybrid\64bit\Vapoursynth\Scripts\vspreview.exe\__main__.py", line 4, in <module>
  File "F:\Hybrid\64bit\Vapoursynth\Lib\site-packages\vspreview\__init__.py", line 1, in <module>
    from . import qt_patch  # noqa: F401
    ^^^^^^^^^^^^^^^^^^^^^^
  File "F:\Hybrid\64bit\Vapoursynth\Lib\site-packages\vspreview\qt_patch.py", line 1, in <module>
    from PyQt6.QtCore import Qt
ImportError: DLL load failed while importing QtCore: Die angegebene Prozedur wurde nicht gefunden.

How can I tell vspreview where to look for the Qt libraries? (They got installed in the Vapoursynth\Lib\site-packages\PyQt6\Qt6\bin-folder)

Afaik you need to put your portable install in PATH so that it can find python3.dll since qt imports that. It probably is finding a wrong version or none at all and is erroring on that. Can you try putting it in path? If that works i can put the parent path of the current exe/dll in PATH automatically to patch qt for portable installs

Hmm,... I got my portable Python in my Vapoursynth folder:

using:

and then

F:\Hybrid\64bit\Vapoursynth>Scripts\vspreview.exe

still fails

echo %PATH% does properly show that f:\Hybrid\64bit\Vapoursynth was added to the PATH.

i'm talking about the python portable install

Setsugennoao commented 8 months ago

Wait, just noticed you merged both folders... this is a weird install

Selur commented 8 months ago

Yes, that is why I wrote in my first sentence "I got my portable Python in my Vapoursynth folder" ;) It's working and easily portable (for example on an usb stick). :) ¯\(ツ)/¯ for amusement: https://forum.doom9.org/showthread.php?p=1992302#post1992302

Setsugennoao commented 8 months ago

I can reproduce only by removing python3.dll, and have no idea why pyqt can't import it in your setup. if you can give me simple reproduciple steps in a venv i might be able to look further into it.

Despite all of this, it's not an issue with vspreview; most I can do is patch pyqt (if I can at all).

Selur commented 8 months ago

Steps to reproduce with setting up the environment like I have:

create a new empty Vapoursynth-folder
download 'Windows embeddable package (64-bit)' from https://www.python.org/downloads/release/python-3111/
extract the Python download into the download into the 'Vapoursynth'-folder
download 'VapourSynth64-Portable-R65-RC1' from https://github.com/vapoursynth/vapoursynth/releases
extract the Vapoursynth portable download into the 'Vapoursynth'-folder
download get-pip.py from https://bootstrap.pypa.io/get-pip.py and save it into the 'Vapoursynth'-folder
opened a 'Windows Command Prompt'-window and navigate into the 'Vapoursynth'-folder
installed pip by calling : python get-pip.py
opened the python311._pth in a text editor and added the following to lines above anything else in that file and saved the file
```
Scripts
Lib\site-packages
```
call python -m pip install vspreview
call Scripts/vspreview

No problem, if you can't look into it. I probably can come up with something to get it working, I just hoped you or someone else already was using vspreview in a portable environment and knew that I just needed to change xy to get it working.

Thanks for spending your time on this. :)
