Developer Installation (Windows)
This section describes how to install the app (CLI and GUI) from source.

Note

You may want to use Windows WSL instead of Windows native installation and follow the instructions in the README.md instead.

Download and install system dependencies

Open a PowerShell as Administrator and install the following programs via winget

winget install --id Gyan.FFmpeg -e --source winget
winget install --id Git.Git -e --source winget
winget install --id Python.Python.3.13 -e --source winget
winget install --id MSYS2.MSYS2 -e --source winget
winget install --id Microsoft.VisualStudio.2022.BuildTools -e --source winget --silent --override "--wait --quiet --add ProductLang En-us --add Microsoft.VisualStudio.Workload.VCTools --includeRecommended"
winget install --id Rustlang.Rustup -e --source winget
winget install --id Microsoft.VCRedist.2013.x64 -e --source winget
winget install --id Microsoft.VCRedist.2013.x86 -e --source winget
winget install --id GnuWin32.Patch -e --source winget
set-ExecutionPolicy RemoteSigned
Then restart your computer

Build system dependencies via gvsbuild

Open a PowerShell as regular user and prepare the build environment. You may want to adjust the $project and point to another directory of your choice. In the following it will be used to build and install system dependencies, and we'll download and install Lada it in this location.

$project = "C:\project"
mkdir $project
cd $project
py -m venv venv_gvsbuild
.\venv_gvsbuild\Scripts\Activate.ps1
pip install gvsbuild pip-system-certs
Now that the gvsbuild build environment is set up we can build the remaining system dependencies which we couldn't install via winget. Grab a coffee, this will take a while...

gvsbuild build --configuration=release --build-dir='./build' --enable-gi --py-wheel gtk4 adwaita-icon-theme pygobject libadwaita gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-rtsp-server gst-python --extra-opts ogg:-DCMAKE_POLICY_VERSION_MINIMUM=3.5;
Tip

If the build fails with

AttributeError: module 'distutils' has no attribute 'ccompiler'. Did you mean: 'compilers'?

add the following line as a workaround

import distutils.ccompiler
at the beginning of the file

.\build\build\x64\release\gobject-introspection_gvsbuild-meson\giscanner\ccompiler.py
then re-run the gvsbuild command again.

Once the build is done prepare your environment variables to include the build artifacts of gvsbuild

$env:Path = $project + "\build\gtk\x64\release\bin;" + $env:Path
$env:LIB = $project + "\build\gtk\x64\release\lib;" + $env:LIB
$env:INCLUDE = $project + "\build\gtk\x64\release\include;" + $project + "\build\gtk\x64\release\include\cairo;" + $project + "\build\gtk\x64\release\include\glib-2.0;" + $project + "\build\gtk\x64\release\include\gobject-introspection-1.0;" + $project + "\build\gtk\x64\release\lib\glib-2.0\include;" + $env:INCLUDE
Note

These variables need to be set for the next steps but also whenever you start lada.

Build remaining system dependencies

We need to build the Gstreamer GTK4 plugin (needed for the GUI video player) ourselves as it cannot be built with gvsbuild yet

git clone https://gitlab.freedesktop.org/gstreamer/gst-plugins-rs.git -b 0.13
cd gst-plugins-rs
cargo install cargo-c
cargo cinstall -p gst-plugin-gtk4 --prefix ($project + "\build\gtk\x64\release") --libdir ($project + "\build\gtk\x64\release\lib")
If gst-inspect-1.0.exe gtk4paintablesink does not return an error everything went fine.

Congrats! You've setup up all system dependencies at this point so we can now install Lada (and it's python dependencies) itself.

Get the source

cd $project
git clone https://github.com/ladaapp/lada.git
cd lada
Create a virtual environment to install python dependencies

py -m venv .venv
..venv\Scripts\Activate.ps1
Install PyTorch

Install python dependencies

pip install -e '.[basicvsrpp]'
For the GUI we'll need to install the Python wheels we've built earlier with gvsbuild:

pip install --force-reinstall (Resolve-Path ($project + "\build\gtk\x64\release\python\pygobject*.whl))
pip install --force-reinstall (Resolve-Path ($project + "\build\gtk\x64\release\python\pycairo*.whl))
Apply patches

On low-end hardware running mosaic detection model could run into a timeout defined in ultralytics library and the scene would not be restored. The following patch increases this time limit:

patch -u .venv/lib/site-packages/ultralytics/utils/ops.py patches/increase_mms_time_limit.patch
Disable crash-reporting / telemetry of one of our dependencies (ultralytics):

patch -u .venv/lib/site-packages/ultralytics/utils/init.py patches/remove_ultralytics_telemetry.patch
Compatibility fix for using mmengine (restoration model dependency) with latest PyTorch:

patch -u .venv/lib/site-packages/mmengine/runner/checkpoint.py patches/fix_loading_mmengine_weights_on_torch26_and_higher.diff
Download model weights

Download the models from the GitHub Releases page into the model_weights directory. The following commands do just that

Invoke-WebRequest 'https://github.com/ladaapp/lada/releases/download/v0.7.1/lada_mosaic_detection_model_v3.1_accurate.pt' -OutFile ".\model_weights\lada_mosaic_detection_model_v3.1_accurate.pt"
Invoke-WebRequest 'https://github.com/ladaapp/lada/releases/download/v0.7.1/lada_mosaic_detection_model_v3.1_fast.pt' -OutFile ".\model_weights\lada_mosaic_detection_model_v3.1_fast.pt"
Invoke-WebRequest 'https://github.com/ladaapp/lada/releases/download/v0.2.0/lada_mosaic_detection_model_v2.pt' -OutFile ".\model_weights\lada_mosaic_detection_model_v2.pt"
Invoke-WebRequest 'https://github.com/ladaapp/lada/releases/download/v0.6.0/lada_mosaic_restoration_model_generic_v1.2.pth' -OutFile ".\model_weights\lada_mosaic_restoration_model_generic_v1.2.pth"
If you're interested in running DeepMosaics' restoration model you can also download their pretrained model clean_youknow_video.pth

Invoke-WebRequest 'https://drive.usercontent.google.com/download?id=1ulct4RhRxQp1v5xwEmUH7xz7AK42Oqlw&export=download&confirm=t' -OutFile ".\model_weights\3rd_party\clean_youknow_video.pth"
Now you should be able to run the CLI by calling lada-cli to the GUI by lada.
write based on this install guide bat file that would install all needed things for GUI version for venv called lada

Certainly! Below is a Windows batch script (install_lada_gui.bat) based on the instructions you provided. It automates the installation of system dependencies via winget, sets up the build environment for gvsbuild, builds dependencies, installs Lada and Python dependencies for the GUI version in a venv named lada.

Notes about the script
Run this script in PowerShell as Administrator for the first part since it needs to install via winget and change ExecutionPolicy.
After rebooting the system (a manual step required by the guide), run the second part in a normal PowerShell (not admin) to build and install Lada.
The script assumes you want the project folder at C:\project. Change the $project variable to another path if needed.
The script uses PowerShell commands inside the batch file by invoking powershell -Command "...".
Patching steps assume the patch files are present in the patches folder inside lada repo folder.

How to use
Open PowerShell as Administrator and run:

.\install_lada_gui.bat
The script will install the system dependencies via winget and set the execution policy.
After installation, reboot your PC (the script will prompt for this).
Once rebooted, open PowerShell as a normal user, and run the script again to continue the build & installation.
Feel free to ask if you want me to turn this into a pure PowerShell script or separate scripts for admin/non-admin phases.

I don't need visual studio build tools and vcdredist 2013 since its already installed, also project path would be I:\Lada. Also I don't need to insteall Python 3.13 in my Windows globally, preferably change script to make it installed and used portably from same project folder

Got it! I'll update the script accordingly:

Remove Microsoft.VisualStudio.2022.BuildTools and VCRedist 2013 installs.
Change project directory to I:\Lada.
Do not install global Python 3.13; instead, download portable Python into the project folder and use it there.
Adapt subsequent calls to use this portable Python binary for the whole install process (creating venvs, pip installs, etc).
Things to note for portable Python:
We will download the official embeddable zip of Python 3.13, unzip it inside the project folder (e.g. I:\Lada\python-portable).
Embedded Python misses some features like pip and venv by default, so sometimes people use the "web installer" or full MSI.
Since you want portable and full features, an alternative approach is to download the official full Windows installer as an embeddable zip and/or unpack full Python from official distribution, or Python embeddable (with added scripts).
For simplicity, I'll put a helper to download the official full Windows embeddable zip (from Python 3.13 release) and enable pip manually.
Here's an updated batch script that:

Downloads Python 3.13 embeddable zip into I:\Lada\python-portable
Extracts it
Installs pip inside portable Python automatically
Uses this python.exe for creating and activating venvs and all pip installs
Skips VS Buildtools and vc redist installs
Uses project folder = I:\Lada

Explanation of changes:
Removed Visual Studio 2022 BuildTools and VCRedist 2013 installs.
Python 3.13 is downloaded as embeddable zip into %project%\python-portable.
Powershell modifies the embeddable .pth file to enable import site so pip and venv work.
Runs get-pip.py to bootstrap pip inside portable Python.
All following venv creation and pip installs use this embedded Python executable (%project%\python-portable\python.exe).
Project folder set to I:\Lada.
Added some checks so steps only happen if missing.
Used powershell commands inside batch for convenience.
How to use the updated script
Open PowerShell as Administrator: Run the batch script:

.\install_lada_gui_portable.bat
The first step downloads portable Python, installs system winget dependencies without VS tools and VCRedist, sets the execution policy and asks you to restart.
Restart your computer.
Open PowerShell as normal (not admin) and re-run the script to continue the build and install.
If you want, I can also provide:

A pure PowerShell script variant instead,
Help with fixing potential permission or path issues,
Additional notes or troubleshooting instructions.
Just ask!

I just need that it would 100% work at Windows 10 x64 and would be 100% portable, not matter is it's uses powershell or not, preferably script goes 1 click install without PC rebooting if possible

Thanks for clarifying — you want a single fully portable one-click install script on Windows 10 x64, without rebooting, without global installs (no VS Build tools, no global python), that sets up everything needed for Lada GUI inside a single project folder (say I:\Lada), and works reliably.

What’s possible (and limitations)
Some winget dependencies (like MSYS2, Rust, etc.) normally require installation and reboot or logoff to work properly, especially for path setup.
MSYS2 and Rust installation via winget normally triggers environment setup that often requires reboot or at least a re-login.
Visual Studio Build Tools is excluded, so we avoid that.
Portable Python venv and dependencies are possible fully portable in the project folder on Windows.
Automatically applying environment variables and path without reboot is possible in session, but terminal windows launched earlier won’t see them — you have to open new ones.
The GUI binary (lada) may depend on system PATH for GTK and GStreamer binaries — which you can set in a script or batch file before launching.
Given these, the recommended approach is:
Use a PowerShell script that:
Checks and installs missing winget dependencies that don’t need reboot (skip those that do).
Downloads a full standalone portable Python 3.13 into project folder (can just download from official python.org installer in embeddable zip form).
Installs pip into portable python.
Creates and uses python venv inside project folder.
Runs gvsbuild installation steps including GTK/GStreamer libs.
Sets environment variables dynamically for the session.
Clones lada repo, installs python dependencies including GUI wheels.
Downloads model weights.
Applies patches.
Provides instructions or even launches the GUI with env vars set.
Skip reboot requirement by skipping dependencies that explicitly require reboot or would make issues.
You must open a new PowerShell window after script finishes to have environment variables take effect, or script can spawn a new powershell with correct env vars to run lada.
Here's a single PowerShell script that attempts this. It:

Installs only minimal winget packages (skips those needing reboot).
Downloads portable python 3.13 embeddable.
Boostraps pip.
Creates venv and installs all python dependencies.
Runs gvsbuild.
Builds gst-plugin.
Downloads model weights.
Sets env vars for session.
Runs lada GUI at the end (optionally).
Requires Windows 10 x64 with PowerShell 5+ and internet connection.
PowerShell Script
Save this as install_lada_gui_portable.ps1 and run in a PowerShell window as Administrator the first time, ideally Run as Administrator, but not always strictly necessary:

# End of script
How to use:
Save the above as install_lada_gui_portable.ps1.
Open PowerShell as administrator, navigate to the script folder, and run

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
.\install_lada_gui_portable.ps1
Script will install necessary winget tools (without VS or VCRedist), download portable Python embedded to I:\Lada\python-portable, set up virtual envs, build all necessary dependencies, clone Lada repo, install python dependencies, apply patches, and download models.
At the end it will launch the GUI with the correct environment variables set.
Why this works the way it does:
Winget installs only minimal packages that don't require reboot.
Python embeddable version is used fully portable inside your project folder, no global install.
Environment variables needed by GTK, GStreamer, and your Python environment are injected to the current session and used when launching GUI.
Limitations & notes:
If you want to install MSYS2 or Rust in a way that is fully path-persistent, you may need to restart or set PATH yourself for later sessions.
If lada.exe doesn’t launch because path issues remain, launch via this PS session or open a new PowerShell window and manually set PATH variables shown above before running.
If you want, I can bundle this as a single executable or create a standalone .bat that invokes PowerShell with this script embedded.

Let me know if you want me to do that or tweak it!

yes

Great! I'll provide you with a complete one-click portable installer packaged as a single .bat file that:

Runs PowerShell inline with the full install script embedded.
Uses portable Python embedded.
Installs all minimal winget deps that don’t require reboot.
Builds dependencies and lada.
Sets environment variables temporarily.
Launches lada GUI at the end.
You will just need to:

Save the .bat file anywhere (e.g., install_lada_portable.bat).
Run it once (Run as Administrator recommended).
Wait for it to finish, GUI will launch automatically at end.
[install_lada_portable.bat]

How to run:
Save above to install_lada_portable.bat
Run as Administrator (right-click → Run as Administrator) to allow winget installs.
Wait patiently — script downloads files, sets up portable python, builds from source, downloads models.
At the end, Lada GUI will auto-launch in your project folder (I:\Lada\lada).
Notes:
Script does not require reboot.
If a package is already installed via winget, it will skip reinstallation.
If you want to run lada GUI later, open PowerShell and run:

cd I:\Lada\lada
.\.venv\Scripts\Activate.ps1
lada
For multiple runs, you can create a shortcut or simply rerun this batch (or just activate and run).
Please let me know if you want me to:

Bundle this with portable CUDA PyTorch installation same folder as
Provide troubleshooting tips for Windows 10 environment path issues

Sure! I'll integrate support for CUDA-enabled PyTorch wheels installation (for CUDA 12.6 or 12.8), using your preferred pip install commands, into the portable installer script, and also provide troubleshooting tips for common Windows 10 environment/path issues.

1) Updated part of the installer script for CUDA PyTorch wheels
You can choose CUDA 12.8 or 12.6 by setting a variable in the script.

I’ll adapt the final script snippet for installing PyTorch accordingly, and store it inside the same portable Python venv in the project folder.

Updated snippet for PyTorch install in PowerShell inside the full install script
Change this block in the PowerShell script:


# Choose CUDA version here (possible values: "cu128", "cu126", or "cpu")
$cudaVersion = "cu128"

Write-Host "Installing PyTorch for CUDA version: $cudaVersion"

switch ($cudaVersion) {
    "cu128" {
        pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128
    }
    "cu126" {
        pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu126
    }
    default {
        Write-Host "Installing CPU-only PyTorch"
        pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cpu
    }
}
Put this in place of the vanilla CPU-only install inside the Setup-LadaPython function or wherever you run the pip commands for PyTorch.

2) Portable CUDA PyTorch installation notes
The PyTorch CUDA wheels are large (~1-2 GB), so ensure enough disk space.
This will install CUDA runtime libraries inside the Python venv, you do not need to install system CUDA separately.
Make sure GPU and drivers are compatible with your chosen CUDA version.
If you want to switch CUDA versions, just change the $cudaVersion string as above and re-run the installer or pip install command.
3) Windows 10 environment path troubleshooting tips
Working with portable Python + GTK + GStreamer + Rust + MSYS2 can lead to PATH issues in Windows 10 x64.

Common issues & fixes
1. GTK/GStreamer DLLs fail to load — error like "DLL not found" or "cannot load library"
Verify you launched Lada GUI from a PowerShell / cmd session where the environment variables are set properly.
Environment variables to ensure:

PATH includes:  I:\Lada\build\gtk\x64\release\bin
LIB includes:   I:\Lada\build\gtk\x64\release\lib
INCLUDE includes the various gtk and gobject-introspection include folders (less critical for runtime)
You can echo your path in your session:

echo $env:PATH
If you run Lada GUI from a shortcut or double-click and PATH is missing, it will fail to locate GTK libraries.
Solution: Use the provided PowerShell script or batch file to activate the environment and run GUI.
2. cargo command or Rust tools not found
Rust installed via winget installs in %USERPROFILE%\.cargo\bin. Sometimes this path is not included in your default environment PATH.
Open a new PowerShell window after installation to get the updated PATH.
If you want to add Rust tooling path manually:

$env:PATH += ";" + "$env:USERPROFILE\.cargo\bin"
3. MSYS2 tools or patch not recognized
MSYS2 installs similar to Rust, get added to user PATH on install completion.
Sometimes you need to add MSYS2 binaries folder manually:

$env:PATH += ";C:\msys64\usr\bin"
Adjust path to MSYS2 install location as needed.
4. Python venv missing modules or pip fails
Ensure you are activating the correct venv via:

.\venv_gvsbuild\Scripts\Activate.ps1
.\lada\.venv\Scripts\Activate.ps1
Confirm pip works inside venv:

pip --version
If pip missing after activating venv, try reinstalling pip via bootstrap:

python -m ensurepip --upgrade
Useful commands to troubleshoot any environment variable:

# Show Windows system path (all env path entries)
[Environment]::GetEnvironmentVariable("PATH", "Machine")

# Show User path entries
[Environment]::GetEnvironmentVariable("PATH", "User")

# Show current PowerShell session path
$env:PATH
Make sure the required paths for Rust, MSYS2, GTK GStreamer binaries, Python portable and venv activate Scripts are present in $env:PATH.

Summary
Change the $cudaVersion variable in the install script to cu128 or cu126 for CUDA-enabled PyTorch.
The script will install portable Python, gvsbuild dependencies, gst plugins, lada with dependencies including the CUDA PyTorch wheels.
Environment variables for GTK/GStreamer libs and Rust/MSYS2 tools must be set in your PowerShell session before running lada or the script launches lada GUI with the correct env.
If a command like cargo or patch is missing, manually add their bin folders to PATH or restart your PowerShell session after install.
If you want me to update the full one-click batch script including CUDA PyTorch install and break down the troubleshooting notes neatly as a README, just ask!

First install dependencies, one can use choco to do this:

choco install ffmpeg-full

choco install msys2

choco install git

Create & Use a Python Virtual Environment for lada
Open a Windows PowerShell(7.5) Create a virtual environment for your project. You can use Command Shell but later on you will need PowerShell for other actions.

md D:\MyProjects\LadaEnv312
cd D:\MyProjects\LadaEnv312
py -m venv .\

Scripts\Activate.PS1
PyTorch & MMCV Installation into Virtual Environment [Required in all cases]

Install Pytorch - Ref: https://pytorch.org/get-started/locally/

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu124
Clone the Project
Make sure you are in at the root of your venv, source will be cloned to a subdirectory called .lada

git clone https://github.com/ladaapp/lada.git
Build & Install lada

python -m pip install -e ".[basicvsrpp]"
Running the CLI-Version
Before you run the cli version or GUI for that matter, you need to download the models, create a Result directory etc.

(1) Add lada to PYTHONPATH

PYTHONPATH=D:\MyProjects\LadaEnv312\lada
(2) Download models into the model_weights directory under lada

Invoke-WebRequest -Uri https://github.com/ladaapp/lada/releases/download/v0.2.0/lada_mosaic_detection_model_v2.pt -OutFile D:\MyProjects\LadaEnv312\lada\model_weights/lada_mosaic_detection_model_v2.pt
Invoke-WebRequest -Uri https://github.com/ladaapp/lada/releases/download/v0.6.0/lada_mosaic_restoration_model_generic_v1.2.pth -OutFile D:\MyProjects\LadaEnv312\lada\model_weights/lada_mosaic_restoration_model_generic_v1.2.pth
At this point, you are ready to check if the installation is working:

lada-cli --version
Output looks like this:

(LadaEnv313) PS D:\MyProjects\LadaEnv313\lada> lada-cli --version
Lada: 0.7.0-dev
(LadaEnv313) PS D:\MyProjects\LadaEnv313\lada>
Information below the line left in place for reference. I have used the above steps with minor tweaks to upgrade to Python 3.13 (LadaEnv313) and Torch/Cuda 12.6. (https://download.pytorch.org/whl/cu126)

[Updated on 03/23/2025]
These Instructions are based on my experience installing on multiple Windows 11 machines. At this time, only CLI version is working.

First install dependencies, one can use choco to do this:

choco install ffmpeg-full

choco install msys2

choco install git

choco install gstreamer

choco install visualstudio2022-workload-vctools

Notes:
gstreamer is required for GUI version which is currently not working on Windows due to PyGObject Build Issues. Visual Studio is only required if you need to compile and build certain dependencies, say ffmpeg. If not lada does not require this. MSys2 is optional, the only use I had for it was to apply patches, one can do that manually. I strongly recommend that you get MSys2.

Installing GTK [Not required for CLI]
Download the October Release of GTK ZIP File from here: https://github.com/wingtk/gvsbuild/releases/tag/2024.10.0
Extract the contents of the ZIP file to D:\MyPrograms\GTK. Make sure you get right version, as anything after October is built with Python 3.13, and won't be compatible with 3.12. MMCV does not support Python 3.13 yet.

Add the following Environment Variables

Path=D:\MyPrograms\GTK\bin
LIB=D:\MyPrograms\GTK\lib
INCLUDE=D:\MyPrograms\GTK\include;D:\MyPrograms\GTK\include\cairo;D:\MyPrograms\GTK\include\glib-2.0;D:\MyPrograms\GTK\include\gobject-introspection-1.0;D:\MyPrograms\GTK\lib\glib-2.0\include
Create & Use a Python Virtual Environment for lada
Open a Windows PowerShell(7.5) Create a virtual environment for your project. You can use Command Shell but later on you will need PowerShell for other actions.

md D:\MyProjects\LadaEnv312
cd D:\MyProjects\LadaEnv312
py -m venv .\

Scripts\Activate.PS1
Add PyGObject and PyCairo to the virtual environment [Not Required for CLI]

pip install --force-reinstall (Resolve-Path D:\MyPrograms\GTK\wheels\PyGObject*.whl)
pip install --force-reinstall (Resolve-Path D:\MyPrograms\GTK\wheels\pycairo*.whl)
PyTorch & MMCV Installation into Virtual Environment [Required in all cases]

Install Pytorch - Ref: https://pytorch.org/get-started/locally/

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu124
Install MMCV

pip install --extra-index-url https://miropsota.github.io/torch_packages_builder mmcv==2.2.0
Clone the Project
Make sure you are in at the root of your venv, source will be cloned to a subdirectory called .lada

git clone https://github.com/ladaapp/lada.git
Build & Install lada

python -m pip install -e ".[basicvsrpp]"
The above command will only install lada-cli! - verified successful build and running of cli version[3/13.2025].

Running the CLI-Version
Before you run the cli version or GUI for that matter, you need to download the models, create a Result directory etc.

(1) Add lada to PYTHONPATH

PYTHONPATH=D:\MyProjects\LadaEnv312\lada
(2) Download models into the model_weights directory under lada

Invoke-WebRequest -Uri https://github.com/ladaapp/lada/releases/download/v0.2.0/lada_mosaic_detection_model_v2.pt -OutFile D:\MyProjects\LadaEnv312\lada\model_weights/lada_mosaic_detection_model_v2.pt
Invoke-WebRequest -Uri https://github.com/ladaapp/lada/releases/download/v0.6.0/lada_mosaic_restoration_model_generic_v1.2.pth -OutFile D:\MyProjects\LadaEnv312\lada\model_weights/lada_mosaic_restoration_model_generic_v1.2.pth
(3) Create Result Directory

md D:\MyProjects\LadaEnv312\lada\Result
Invoke CLI version with the following command ( --device is optional, I use that to direct lada to use the first cuda device as I have a machine with Tesla M60 that has two GPU, I run two restorations at once)

lada-cli --input D:\ToClean\TestClip.mp4 --output .\Result\TestClip-Restored-v2.mp4 --device cuda:0
Result should look like this:

D:\MyProjects\LadaEnv312\lada\lada\basicvsrpp\mmagic\concat_visualizer.py:17: SyntaxWarning: invalid escape sequence '*'

Patching for Training & Low End CPU[Refer to Homepage for more details]

Please note: --dry-run is included below to first check without patching, if the directory is wrong, patch creates directories and makes a mess of things. In Windows, the files are located under Lib\site-packages and not Lib/python312/site-packages!

patch -u --dry-run /d/MyProjects/LadaEnv312/Lib/site-packages/mmengine/runner/loops.py -i /d/MyProjects/LadaEnv312/lada/patches/adjust_mmengine_resume_dataloader.patch

patch -u --dry-run /d/MyProjects/LadaEnv312/Lib/site-packages/ultralytics/utils/ops.py /d/MyProjects/LadaEnv312/lada/patches/increase_mms_time_limit.patch
Once you verify that paths are correct, execute the above commands after removing --dry-run to apply the patches.

From the root directory of the virtual environment I issued the following command:

lada-cli --input .\ShortClipsForTests\TwoMinuteClip.mp4 --output .\Result\MinuteClipClean.mp4

lada-cli seems to have built fine, as it executed without any complaints. However I did get an error. Not sure why.

hey, nice you were able to make it work. you've only mentioned the cli, does the gui work as well?

I thought the issue with filetype I specified. Looks like that is not the case. I am still getting the error message:

i think the issue is that your file extension is uppercase, try to use lowercase for now. will change it to support both / handle it case-insensitive.

@ladaapp, I picked this up again today. However, an error that I seemed to have fixed earlier has come back. Couple of issues:
(1) git clone does not seem to get the new "lada_mosaic_restoration_model_generic_v1.2.pth". Therefore, I used the wget command in unix instructions to fetch it.
(2) Even with the file there, I am getting the following error:

Has anyone gotten the Lada Gui to actually work on Windows by compiling it themselves? The only such cases I could find are when they compile a program inside Msys2 that has libadwaita as a dependency and probably pyinstaller(based off of this project that was also written in python - Varia) @seatv As for IDEs, I think most people just use VS, PyCharm etc

Thanks, I have been using PyCharm. Has not been able to devote any time to this as I have been busy. One of my goals was to find where the input stream was being opened so that I can change it to use hardware acceleration and compare the results. I have not been able to break at that point.

do you have latest & easy method step by step install on windows?

If you start at the top, you will see that most of us on this thread has gotten CLI version to work, following the steps in the first post.

As for GUI, as you can see, we are still figuring things out.

I suggest that you get the CLI version working, I (we) can help if you have specific questions. Then, you can try standing up the GUI version. Not sure that has been successfully done yet.

A packaged version for Windows may not be available in the near future. My guess is that @ladaapp has other higher priority features that he wants to add to lada.

So, are you saying that you installed Feb release of MSYS2 and then got the GUI to run by installing gvsbuild? Something must have changed since the last time I tried gvsbuild. I shall give it a try later today and report back if it works for me.

I just use pip install gvsbuild, not the one you provided https://github.com/wingtk/gvsbuild/releases/tag/2024.10.0 you could reproduce everything via my command that I given both cli and gui the only issue probably might be when using gvsbuild requires to build gst-rtsp-server then build gst-python

Oh, I was using 2024.10.0 as that was the last prebuilt version that supported Py 3.12. Everything after was only released for Py > v3.13

I was only able to get the audio to work, trying to figure out how to get past the wglShareLists issue (seems for some reason some dependencies didn't build with OpenGL support even though I have Windows SDK installed) and trying to figure out why the colors in the video are messed up which are leaving me completely stumped at the moment

@seatv Saw that you had an issue open for this too
Correct, I saw the issue this time too, added the import statement, that fixed the pygobject build issue.

Also got a warning for MSVCR120.dll which was solved by installing Visual C++ Redistributable 2013 x86/x64
For me, this was an error as opposed to warning, the build failed. I installed the Redistributable per instructions here" https://answers.microsoft.com/en-us/microsoftedge/forum/all/msvcr120dll-missing-and-is-not-being-fixed/80381906-8f63-4e20-bee5-e9b96ae0d238

Once I made the two changes, the following build succeeded:
gvsbuild build --configuration=release --build-dir="./gtk4" --enable-gi --py-wheel gtk4 adwaita-icon-theme pygobject libadwaita gstreamer gst-plugins-base gst-rtsp-server gst-python gst-plugins-good --extra-opts ogg:-DCMAKE_POLICY_VERSION_MINIMUM=3.5;
I did was to create a venv just for gvsbuild; may be that is why I did not get any other issues. I did use Py 3.13.3. gvsbuild likes to be on the bleeding edge or so it seems :)

I am going to wait for you all to sort this out.

To make it work for me, in video_preview.py I did -
Either usepathlib to use for URI(which I did below), or you can also use the built-in Gst.filename_to_uri too as I stated earlier(I'm not sure which would be better)
Changed:

lada/lada/gui/video_preview.py

Line 367 in d176489

self.audio_uridecodebin.set_property('uri', 'file://' + self.video_metadata.video_file)
To:


            video_path = pathlib.Path(self.video_metadata.video_file).resolve()
            video_uri = video_path.as_uri()
            self.audio_uridecodebin.set_property('uri', video_uri)
And:

lada/lada/gui/video_preview.py

Lines 429 to 438 in d176489

if paintable.props.gl_context:
video_sink = Gst.ElementFactory.make('glsinkbin', None)
video_sink.set_property('sink', gtksink)
else:
video_sink = Gst.Bin.new()
convert = Gst.ElementFactory.make('videoconvert', None)
video_sink.add(convert)
video_sink.add(gtksink)
convert.link(gtksink)
video_sink.add_pad(Gst.GhostPad.new('sink', convert.get_static_pad('sink')))
To:

if paintable.props.gl_context:
video_sink = Gst.ElementFactory.make('glsinkbin', None)
video_sink.set_property('sink', gtksink)
else:

    video_sink = Gst.Bin.new()
    convert = Gst.ElementFactory.make('videoconvert', None)
    video_sink.add(convert)
    video_sink.add(gtksink)
    convert.link(gtksink)
    video_sink.add_pad(Gst.GhostPad.new('sink', convert.get_static_pad('sink')))
And Lastly:

lada/lada/gui/video_preview.py

Line 469 in d176489

audio_uridecodebin.set_property('uri', 'file://' + self.video_metadata.video_file)
To:


    video_path = pathlib.Path(self.video_metadata.video_file).resolve()
    video_uri = video_path.as_uri()

Edit: I was able to fix this. The version of CUDA I had installed was 12.8 and the instructions show to install 12.4. I just deleted everything in the "LadaEnv312" folder and reinstalled everything again, but installed CUDA 12.8 like this

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu128.

Hi @seatv I was able to follow your instructions and get lada installed on Windows 11, thanks! But when I run it I get an error saying it cannot find CUDA. I do have version 12.8 installed as you can see from my nividia-smi result below.

Image

The only thing I wasn't 100% sure on with your instructions was when adding lada to the Python path. I added it as a system environmental variable like below - that is the only thing I can think of that I might have done wrong.

Image

And at the very top of my 'Path' system variable I've got the CUDA paths

Image

Please let me know what I can do to make this work.

Thanks again for your instructions!

Reading through the development and contributions from you all is amazing. I hope one day there is an easier way to install everything + the GUI on Windows 11.

Thanks for the effort guys! I've set up a Windows 11 VM and was able to install CLI and GUI.
Documentation is available now at https://github.com/ladaapp/lada/blob/main/docs/windows_install.md

As I was only testing on a VM I did not have sound and no Nvidia GPU but the GUI started and i was able to use it to preview and export. I couldn't test WSL as this would need some kind of nested virtualization but AFAIK its just wsl --install and then following the main/Linux install instructions.

I'm closing this ticket now but would appreciate if you could review this document and create a new issue or better yet a PR if I made a mistake.

(I did not run into the issue mention above about OpenGL though)

I am not a Windows user and will not test Lada on Windows so I'm relying on community contributions to keep the docs up-to-date. As you've figured out how to build the app on Windows maybe someone is interested in figuring out how to package it (e.g. via PyInstaller)? 😄

I reset a PC, Windows 11 24H2, installed NVidia drivers, installed CUDA 12.8.1 and then followed your instructions (https://github.com/ladaapp/lada/blob/main/docs/windows_install.md) step by step, up to Step#3, building and installing Gtk Plugin. Not sure what I see below is an error or normal - I am assuming it is an error. I did get a build error in Step-2, but importing dist...compiler fixed that and I was able to move forward:

(venv_gvsbuild) PS D:\MyProjects\GVSBuild> gst-inspect-1.0.exe gtk4paintablesink
No such element or plugin 'gtk4paintablesink'
The third patch command for me had to look like this:

patch -u .venvLib/site-packages/mmengine/runner/checkpoint.py patches/fix_loading_mmengine_weights_on_torch26_and_higher.diff
Looks like the plugin did not build for me:
CLI works fine,

Can you search for gstgtk4.dll in your $project directory? This should have been installed into ($project + "\build\gtk\x64\release\lib\gstreamer-1.0)
If you only find it below gst-plugins-rs then maybe pass --libdir in addition to --prefix but that shouldn't be necessary...

cargo cinstall -p gst-plugin-gtk4 --prefix ($project + "\build\gtk\x64\release") --libdir ($project + "\build\gtk\x64\release\lib")
The third patch command for me had to look like this:
patch -u .venvLib/site-packages/mmengine/runner/checkpoint.py patches/fix_loading_mmengine_weights_on_torch26_and_higher.diff

So the first patches to patch ultralytics were successful? What error do you get when patching mmengine? The path you reported looks weird as it does not include python3.13. This path should point to the file we're patching. The parent directory of mmengine and ultralytics are the same so if there is an error with wrong directory prefix I would have expected that also the first patches fail.

AttributeError: 'NoneType' object has no attribute 'get_property'

That's expected if the gtk4 gstreamer plugin was not correctly installed

Ok, the cargo install statement needs to be explicit, as you suggested above. On doing that. plugin is installed correctly, if not, a new build directory is created in root folder of the drive of $Project drive and installed there, LOL.

mmengine patch failed becasue the site-package directory is wrong. If you go back to my first write up on Windows install, I called this out there as well. Here is what the directory looks like in my venv

Okay, cool then I'll adjust the docs and add the --libdir argument. 👍

On launching lada, the attached image is what I get... now picture.

I think this is what @ConnoisseurProtege reported in #27 as "messed up colors".
Can you adjust lada/gui/video_preview.py
and change this line


    if paintable.props.gl_context:
to


    if paintable.props.gl_context and sys.platform != 'win32':
and add the import for sys by adding at the beginning of the same file the the following line

import sys
This way we're not using GL on Windows even if it is available. Would be a workaround until the root cause is identified. Let me know if this works then I'll fix this add this in master.

In the post above you mentioned that this command worked

patch -u .venvLib/site-packages/mmengine/runner/checkpoint.py patches/fix_loading_mmengine_weights_on_torch26_and_higher.diff
I assume the missing \ between .venv and Lib is just a typo and you used LadaEnv313 instead of .venv?
So the ultralytics package/subdirectory and mmengine are not in the same directory? ultralytics is in LadaEnv313\Lib/python3.13/site-packages as currently assumed by the patch commands but mmengine in LadaEnv313\Lib/site-packages as shown in your screenshot? 🤔

I tried to reproduce this with

py -m test_venv
.\test_venv\Scripts\Activate.ps1
pip install mmengine ultralytics
This will then install both mmengine and ultralytics below .\test_venv\Lib\site-packages .

So no idea how you could end up with some packages in this python3.13 subdir and some directly in Lib and it still works.

Edit: In your first post in #27 you reported these patch commands:

patch -u --dry-run /d/MyProjects/LadaEnv312/Lib/site-packages/mmengine/runner/loops.py -i /d/MyProjects/LadaEnv312/lada/patches/adjust_mmengine_resume_dataloader.patch

patch -u --dry-run /d/MyProjects/LadaEnv312/Lib/site-packages/ultralytics/utils/ops.py /d/MyProjects/LadaEnv312/lada/patches/increase_mms_time_limit.patch
also without python3.13 -> I'll adjust the docs and just drop the python3.13 subdir for all 3 patches...

I had two venvs, one for GTKBuild and one for Lada, I blew away the lada folder and started testing from Step 4 (it will take too long to build Gtk, will test on another machine when I get a GTX 1080 I ordered).

Just noticed one other thing... while installing wheels, the install for pygobject*.whl is invoked, we don't need to issue explicit command for pycairo*.whl, as the first command takes care of it;

One of these days I will do a comparison between the two restoration models. Another thing to add might be download commands for the older detection models, especially v2 ad v3 while faster misses some stuff. [I suppose, this is not needed with 0.7.1 - just realized that after I did the test and just now when I saw that you bumped to 0..7.1]

I got this from the official gvsbuild docs and didn't check why they are not installing both wheels in the same command. I assume there is some reason for it and keep it as they recommend.

One more suggestion... as we are already in .ven/lada, I used ../lib/site....
I had two venvs, one for GTKBuild and one for Lada

The docs also uses two venvs, one for lada and one for gvsbuild so the current patch path is correct if you're using the .venv venv created in lada directory.

You have a ) at the end, please correct.

Thanks, fixed.

The v3.1-accurate model is intended to be a replacement for v2. It was trained on the same data as v3.1-fast but uses a larger model architecture. v2 is even larger and was trained on a different dataset compared to the v3 or v3.1 series. When you're testing v3.1-accurate and think that v2 is still more accurate then please open a new issue.

And the result is...

Nice 👍

yeah, didn't mention it as I hoped that v3.1-accurate will be just better and there is no need for v2 anymore. After a bit more testing v3.1-accurate is not as accurate as I initially saw. For the next release will document and package both v3.1-acurate and v2 as alternatives to the fast detection model until I can come up with something better...

From the above, your directory structure looks like this: C:\project\lada.venv - root of your virtual environment.
Did you execute the git command in that directory? If so, then lada would be cloned to C:\project\lada.venv\lada
You should set your PYTHONPATH to C:\project\lada.venv\lada
Invoke lada or lada-cli from C:\project\lada.venv\lada
If the above are true, then your gstreamer build is not complete.

Please try invoking lada-cli --version from the lada directory.

I use a PS1 file with the following content to setup. I add PYTHONPATH in the system environment variable.

Thanks for sharing all that context from the GitHub discussions. Here is a detailed consolidated analysis of potential pitfalls and troubleshooting tips from these Windows installation issues, along with how to incorporate them into your portable all-in-one installer script — including CUDA PyTorch and environment considerations.

Summary of main issues reported in the discussions
Issue area	Problem & cause summary	Suggested fix or mitigation
GTK/GStreamer GUI missing namespaces / DLL load errors	gi.require_version('Gst', '1.0') fails; DLL load failed while importing _gi
Often caused by missing or incomplete GTK/GStreamer build or incorrect PATHs. Also possible incomplete gst-plugin-gtk4 build/plugin install.	- Ensure full GTK4 and GStreamer, including python gobject introspection dependencies, are properly built and installed.
- Cargo install gst-plugin-gtk4 with explicit --prefix and --libdir.
- Set environment variables PATH, LIB, INCLUDE (correct Windows path separators) for GTK and GStreamer binaries persistently or in the launching shell.
- Modify video_preview.py to disable OpenGL (gl_context) on Windows (if paintable.props.gl_context and sys.platform != 'win32') to avoid color/gl errors.
- Use latest gvsbuild release matching Python version.
- Verify gst-inspect-1.0.exe gtk4paintablesink finds correct plugin.
- Avoid installing GTK/GStreamer with choco, prefer built from source as per instructions.
- Put Python wheels from gvsbuild build first, pip install them to .venv.
Patch fail due to wrong site-packages directory path	Some patch commands fail because python packages are found under Lib/site-packages while others under Lib/python3.13/site-packages. This varies by venv and python installation.	- Use relative patch commands from the .venv folder using ../lib/site-packages/...
- Drop python3.13 subfolder from patch paths if using Python 3.13
ImportError MODEL_WEIGHTS_DIR / missing models causing crashes	Model weight files missing or downloaded to wrong folder.
Patch errors may cause broken imports.	- Always download model weights to model_weights subfolder inside lada source directory.
- Verify the file exists before start.
- Add PYTHONPATH environment variable pointing to lada source folder.
- Create Result folder ahead of time.
Audio processing error in CLI with certain formats	Output container compatibility error for audio codec streaming.
Lossy AAC with ADTS mux mode causes error if output format is not .mp4 or .mkv lowercase.	- Use lowercase .mp4 or .mkv as output extension.
- Disable or improve error handling to pre-check file extension.
- User should manually ensure output format supported.
cargo not found or incorrectly installed rust tooling	Path not set correctly to Rust cargo binaries.
Wrong invocation or environment path.	- Add Rust cargo bin folder (%USERPROFILE%\.cargo\bin) to environment PATH.
- Open new PowerShell session after Rust installation.
- Check cargo --version.
MSYS2 and patch command not found	MSYS2 binaries not in PATH or installed incorrectly.	- Add MSYS2 usr bin folder to PATH.
- Or use the GnuWin32.Patch winget package for patch.exe binary.
- Verify patch --version works before applying patches.
Multiple venvs confusion	Having separate venv for gvsbuild and lada causes confusion about activated environment, patch paths, and python package locations.	- Clearly separate the two venvs.
- Use relative paths for patches.
- Activate the lada venv when running patches, installing python deps, and invoking lada or lada-cli.
Case sensitivity of file extensions (Windows case-insensitive FS but code sensitive)	Using uppercase .MP4 or .MKV can cause "Unsupported file format" errors.	- Always use lowercase extensions .mp4/.mkv when specifying input/output.
- Workaround in code is being implemented but not yet covered in released versions.
OpenGL related color distortion / wglShareLists error on Windows	GTK4 video sink OpenGL context on Windows causes colors to be wrong or errors.	- Patch video_preview.py to disable OpenGL paintable usage on Windows (check platform in code).
CUDA version mismatch or CUDA not found errors	Installing CUDA 12.4 wheels but system CUDA 12.8 installed or vice versa.
CUDA DLLs not in PATH or driver mismatch.	- Match your system CUDA version with PyTorch CUDA wheels, e.g. use cu128 wheels for CUDA 12.8.
- Add CUDA bin and libnvvp folders to system PATH.
- Run nvidia-smi to verify driver and GPU visible.
- Ensure GPU capable and CUDA toolkit installed (not mandatory if using CPU wheels).
GStreamer Python namespaces absent / bindings missing	Incomplete bindings built or missing runtime environment variables causes gi.require_version('Gst', '1.0') to fail.	- Build pygobject and gstreamer python bindings correctly via gvsbuild.
- Install those Python wheels into your venv.
- Use gvsbuild's gtk4 wheels, do not rely on OS GTK installations.
- Set env vars properly.
- Check with gst-inspect-1.0 that plugins are visible.
How to integrate this knowledge in your portable one-click Windows installer (PowerShell / batch):
Choose Python version and gvsbuild release carefully, ideally Python 3.13 and gvsbuild 2024.10.0 or latest supporting Python 3.13.
Build both venv_gvsbuild and lada venv separately:
Install gvsbuild and system libs in the first.
Build and install gtk4, gstreamer, gst plugin gtk4, etc.
Install Python wheels (pygobject, pycairo) from gvsbuild build dir to lada's .venv.
Apply patches using correct relative paths, verify correct python package tree location:

patch -u ../lib/site-packages/ultralytics/utils/ops.py patches/increase_mms_time_limit.patch
patch -u ../lib/site-packages/ultralytics/utils/__init__.py patches/remove_ultralytics_telemetry.patch
patch -u ../lib/site-packages/mmengine/runner/checkpoint.py patches/fix_loading_mmengine_weights_on_torch26_and_higher.diff
Set environment variables dynamically for GTK, GStreamer, Rust, MSYS2 binaries on every shell session:

$env:PATH = "$project\build\gtk\x64\release\bin;$env:PATH"
$env:LIB = "$project\build\gtk\x64\release\lib;$env:LIB"
$env:INCLUDE = "$project\build\gtk\x64\release\include;$project\build\gtk\x64\release\include\cairo;$project\build\gtk\x64\release\include\glib-2.0;$project\build\gtk\x64\release\include\gobject-introspection-1.0;$project\build\gtk\x64\release\lib\glib-2.0\include;$env:INCLUDE"

$env:PATH += ";$env:USERPROFILE\.cargo\bin"
$env:PATH += ";C:\msys64\usr\bin"
Install PyTorch using matching CUDA version wheels, add a variable to switch between cu128, cu126, or cpu.
Edit lada/lada/gui/video_preview.py: Add at top:

import sys
Change OpenGL context check to disable GL on Windows:

if paintable.props.gl_context and sys.platform != 'win32':
    # existing code
else:
    # fallback code without GL usage
Use lowercase file extensions for inputs and outputs.
Add PYTHONPATH environment variable for the lada source folder:

$env:PYTHONPATH = "$project\lada"
or add to system/user environment variables.
Create Result directory before running pushes to output files.
Troubleshooting quick checklist for Windows users:
Symptom	Check / Fix
ValueError: Namespace Gst not available	Make sure GTK/GStreamer built properly, built gst-plugin-gtk4 installs correct DLLs, env vars including PATH are set.
ImportError DLL load failed while importing _gi	GTK Python bindings missing or Python environment incomplete.
Install pygobject and pycairo wheels from gvsbuild build. Ensure PATH set.
patch command not found	Install GnuWin32.patch or MSYS2 (usr/bin) and add to PATH
cargo command not found	Add %USERPROFILE%\.cargo\bin to PATH, open new shell after rust install
FileNotFoundError for model_weights	Download model weights carefully to ${project}\lada\model_weights\
Output video not saved	Make sure output directory exists before running command
Audio output errors with certain formats	Use lowercase .mp4 or .mkv extensions consistently
GUI video colors wrong / OpenGL issue	Patch out paintable.props.gl_context on Windows in video_preview.py
CUDA version mismatch errors or gpu not detected	Use CUDA wheel version matching your driver / CUDA toolkit installation. Check nvidia-smi
Patching errors due to mixed Python package locations	Adjust patch paths relative to .venv folder, check for Lib/site-packages vs Lib/python3.13/site-packages
Example snippet to patch video_preview.py (you can do this in your installer script):

$videoPreviewFile = Join-Path $project "lada\lada\gui\video_preview.py"
(gc $videoPreviewFile) -replace 'if paintable.props.gl_context:', 'if paintable.props.gl_context and sys.platform != "win32":' | Set-Content $videoPreviewFile
(gc $videoPreviewFile) | Select-String -Pattern 'import gi' -SimpleMatch | ForEach-Object {
  # insert 'import sys' after import gi line if not already present
}
# or ensure your script adds "import sys" at top
Summary for your one-click portable installer:
Bundle portable Python embeddable 3.13.
Install minimal winget packages: ffmpeg, git, msys2, rust, patch.
Create separate venvs for build (venv_gvsbuild) and lada .venv.

.SYNOPSIS
    Portable one-click installer for Lada GUI on Windows 10 x64.

.DESCRIPTION
    This script sets up portable Python 3.13, installs system dependencies, builds GTK/GStreamer, Rust plugins,
    installs Lada with CUDA-enabled PyTorch, applies required patches,
    downloads models, and sets environment. It also patches video_preview.py
    to disable OpenGL paintable on Windows.

.NOTES
    Run as Administrator recommended to install winget packages.
    Requires Internet connection.
    Adjust $project and $cudaVersion variables below as needed.

How to run
Save above script as install_lada_portable.ps1.
Open PowerShell as Administrator (important for winget installs).
Run:

Set-ExecutionPolicy -Scope Process -ExecutionPolicy Bypass
.\install_lada_portable.ps1
Wait patiently while it runs all stages, downloading, building, patching.
After completion, follow printed instructions to activate the venv and run GUI.
Summary of troubleshooting tips (also included in script output):
GTK/GStreamer DLL missing or Namespace Gst not available error? Set the environment variables PATH, LIB, INCLUDE to point to the gtk build directories every time you run lada.exe.
gi import fail or _gi DLL load error? Make sure pygobject and pycairo Python wheels are installed from gvsbuild output.
patch not found for applying patches? Add GnuWin32 or MSYS2's usr\bin folder to PATH.
Rust cargo command not found? Add %USERPROFILE%\.cargo\bin to PATH; reopen PowerShell.
CUDA PyTorch errors? Use pytorch wheels for your installed CUDA version (12.6 or 12.8). Check GPU visibility with nvidia-smi.
Use lowercase .mp4 and .mkv file extensions for inputs and outputs.
Create output folders before running commands.
This script and instructions should get you a fully working portable Lada GUI install with CUDA PyTorch support on Windows 10 x64 without reboot.

If you want me to pack this into a single batch file that runs this PowerShell script, or create usage docs/readme, just say!

pack this into a single batch file that runs this PowerShell script also add optional selecting install path, visual tools and vc redist 2013 install like it was in initial script before I told to remove them

Certainly! Below is a single .bat installer file that:

Prompts user (optional) for the install path (default I:\Lada).
Asks if user wants to install Visual Studio Build Tools & Visual C++ Redistributables.
Embeds and runs the complete PowerShell installation script with CUDA PyTorch selection.
Runs PowerShell inline without requiring the user to run separate .ps1 script.
Sets ExecutionPolicy bypass temporarily.
Provides progress info and handles errors.
Save this as install_lada_portable.bat and run as Administrator.

Great! Here’s the small launch helper script and a README you can save alongside your install that will help you easily run Lada GUI with all necessary environment variables set.

1) Launch Helper — run_lada_gui.ps1
Save this PowerShell script alongside your lada folder (e.g., in %installPath%):


<#
.SYNOPSIS
    Launches Lada GUI with all required environment variables for GTK, GStreamer, Python, and CUDA.

.DESCRIPTION
    This script activates the lada Python virtual environment,
    sets required PATH, LIB, INCLUDE, PYTHONPATH environment variables,
    and launches lada.exe, then returns.

.NOTES

# Portable Lada GUI for Windows - Quick Start & Troubleshooting

## Running Lada GUI

Use the provided PowerShell script `run_lada_gui.ps1` in the install folder to launch the GUI with proper environment:

```powershell
.\run_lada_gui.ps1
This script:

Activates the Python virtual environment inside the lada folder.
Sets environment variables needed for GTK4/GStreamer binaries.
Ensures Python modules and plugins are found.
Adds optional Rust/MSYS2 binaries to PATH.
Important Notes
Always use lowercase .mp4 or .mkv file extensions for input/output videos to avoid format errors.
Before running the GUI, ensure you have:
Installed Visual Studio Build Tools if prompted during install.
Matched your CUDA PyTorch wheel version (e.g. cu128 for CUDA 12.8).
Installed Rust and MSYS2 dependencies (done via winget installer).
Downloaded all pretrained model weights (installer does this for you).
If you get errors like Namespace Gst not available or _gi DLL load failed:
Check that environment variables (PATH, LIB, INCLUDE) include your GTK build directories.
Use run_lada_gui.ps1 to launch or manually set these variables in a PowerShell session.
Make sure Python GTK wheels are installed from the gvsbuild output.
If patching errors occur:
Ensure patches are applied with correct relative paths from the lada .venv.
Two virtual environments are in use: one for system libs (venv_gvsbuild) and one for lada python (.venv).
For Rust tools (cargo) or patch command errors:
Confirm that %USERPROFILE%\.cargo\bin and MSYS2's usr\bin directories are included in your system or session PATH.
Common Commands
Activate lada python environment manually:


cd path\to\lada
.\.venv\Scripts\Activate.ps1
Run lada GUI:


lada
Check CUDA GPU:


nvidia-smi
Troubleshooting
Symptom	Cause	Fix
"Namespace Gst not available"	GTK/GStreamer not built or PATH missing	Use run_lada_gui.ps1 or set env vars to GTK build folders
ImportError: DLL load failed _gi	pygobject or pycairo missing or PATH	Reinstall Python GTK wheels from gvsbuild; check PATH
Patch command not found	patch.exe missing	Install GnuWin32 patch or add MSYS2 usr/bin to PATH
CUDA not found / PyTorch mismatch	CUDA driver/wheels version mismatch	Use installer CUDA version matching your system CUDA
Output file not saved	Output directory missing	Manually create output folder before run
Video colors messed up	OpenGL GL context broken on Windows	Patched video_preview.py disables GL paintable on Windows
Support
For detailed install instructions and latest changes, see:

https://github.com/ladaapp/lada/blob/main/docs/windows_install.md

Enjoy your portable Lada GUI on Windows!



---

### How to use these

- Put `run_lada_gui.ps1` in the root folder where lada is installed (`%installPath%`).
- Use it instead of double-clicking lada.exe to ensure correct env is set.
- Read `README_PortableLada_Windows.md` for common issues and fixes.
- Modify/install as needed for your setup.

---

If you'd like, I can provide you with:

- A `.bat` launcher version wrapping `run_lada_gui.ps1`
- A zip package containing both this launcher script and README
- Or help customizing scripts further

Just ask!
yes

Absolutely! Here's everything bundled together for you:

1) Single launcher batch file: run_lada_gui.bat
Save this file next to your lada folder (in your install root). This batch file will invoke the PowerShell launcher script with minimal hassle:


@echo off
setlocal

set "SCRIPT=%~dp0run_lada_gui.ps1"
if not exist "%SCRIPT%" (
    echo ERROR: Cannot find run_lada_gui.ps1 in the script folder.
    pause
    exit /b 1
)

powershell -NoProfile -ExecutionPolicy Bypass -File "%SCRIPT%"
endlocal
2) PowerShell launcher script: run_lada_gui.ps1
Save this in the same folder as above (%installPath%):


<#
.SYNOPSIS
    Launches Lada GUI with the required environment setup.

.DESCRIPTION
    Activates Lada Python venv, sets GTK/GStreamer and other env vars,
    then launches lada.exe.

) -join ';'

$ladaDir = Join-Path $projectDir 'lada'
$venvActivate = Join-Path $ladaDir '.venv\Scripts\Activate.ps1'

# Add required folders to environment variables for current session
$env:PATH = "$gtkBin;$env:PATH"
$env:LIB = "$gtkLib;$env:LIB"
$env:INCLUDE = "$gtkInclude;$env:INCLUDE"
$env:PYTHONPATH = $ladaDir

# Optionally add Rust and MSYS2 to PATH if needed
$env:PATH += ";$env:USERPROFILE\.cargo\bin;C:\msys64\usr\bin"

Write-Host "Activating Lada venv..."
. $venvActivate

Write-Host "Launching Lada GUI..."
Start-Process -FilePath (Join-Path $ladaDir 'lada.exe')

Write-Host "Lada GUI launched. You may close this window."
3) README snippet: README_PortableLada_Windows.md
Save this file alongside the other two:


# Portable Lada GUI for Windows - Quick Start and Troubleshooting

## How to Run

Use the included `run_lada_gui.bat` launcher:

```cmd
run_lada_gui.bat
This will:

Activate the Python virtual environment.
Set required environment variables for GTK/GStreamer.
Launch the Lada GUI application.
Important Tips
Use lowercase .mp4 or .mkv extensions for all input/output video files.
If you encounter errors regarding GTK or Python GI modules:
Ensure environment variables PATH, LIB, INCLUDE include GTK build directories.
Launch using the provided batch or PowerShell launchers.
Rust (cargo) and patch commands require respective binaries in PATH. Add:
%USERPROFILE%\.cargo\bin
C:\msys64\usr\bin
CUDA PyTorch wheels require matching your installed CUDA drivers; verify with nvidia-smi.
Output folders must exist before running Lada commands.
Troubleshooting Common Errors
Symptom	Cause	Solution
Namespace Gst not available	GTK/GStreamer libs missing or PATH incorrect	Use launcher scripts to set env vars, or set Windows environment variables accordingly
DLL load failed while importing _gi	pygobject or pycairo wheels missing	Reinstall wheels via gvsbuild build outputs
Patch command not found	patch.exe missing	Install GnuWin32 patch or MSYS2 and add usr\bin to PATH
Model weights not found	Missing or wrongly placed model files	Ensure model weights downloaded inside model_weights folder
PyTorch CUDA errors	CUDA driver and wheel versions mismatch	Use CUDA version matching your system
Video colors are incorrect	OpenGL paintable issue on Windows	The patched video_preview.py disables GL on Windows
Support and More Info
Official docs: https://github.com/ladaapp/lada/blob/main/docs/windows_install.md

# How to package and distribute

Just zip these three files together:

- `install_lada_portable.bat` (installer)
- `run_lada_gui.bat` (launcher batch)
- `run_lada_gui.ps1` (PowerShell GUI launcher)
- `README_PortableLada_Windows.md` (docs)

Place in the root folder where you want Lada installed. Run `install_lada_portable.bat` **as Admin** the very first time. Then use `run_lada_gui.bat` to launch GUI anytime.

---

If you want, I can generate a ready-to-go zip archive with these files or help generate shortcuts, desktop icons, or a fully self-extracting installer — just ask!
when I select CUDA version in bat file below that you created it just closes:
@echo off

pause

Your batch script closes immediately because the %ERRORLEVEL% checks with choice don’t work quite as expected when multiple if errorlevel checks are stacked without care about ordering; plus the script lacks a pause or cmd /k to keep window open on error. Also, your powershell -Command inline script string can prematurely terminate if any variable contains unescaped characters or if there’s a syntax error, causing PowerShell to close silently.

How to fix:
Fix choice errorlevel checks:
The recommended pattern is to check from highest number to lowest because if errorlevel N is true for errorlevel >= N.
So change:


if errorlevel 3 set "cudaVersion=cpu"
if errorlevel 2 set "cudaVersion=cu126"
if errorlevel 1 set "cudaVersion=cu128"
to


if errorlevel 3 set "cudaVersion=cpu"
if errorlevel 2 if not errorlevel 3 set "cudaVersion=cu126"
if errorlevel 1 if not errorlevel 2 set "cudaVersion=cu128"
or better:


choice /c 123 /n /m "Enter choice [1-3]: "
set "cudaVersion=cu128"
if errorlevel 3 set "cudaVersion=cpu"
if errorlevel 2 set "cudaVersion=cu126"
Explanation:

errorlevel is tested top-down (3 first means it matches 3 or more, which is always true for 3, then next line 2 matches 2 or more including 3, so order matters).
Add debugging to PowerShell inline:
Add -NoExit flag for debugging or redirect output to a log file so you can see errors.
Example:


powershell -NoProfile -ExecutionPolicy Bypass -Command "try { ... } catch { Write-Host 'ERROR:' $_; pause }"
Make sure variables passed inside PowerShell string are properly quoted and escaped.
Batch variable %installPath% with spaces or special chars could break the PowerShell script string. Use double quotes properly and escape as needed or pass via environment variables or arguments.
Minimal corrected CUDA selection snippet example:

choice /c 123 /n /m "Enter choice [1-3]: "
set "cudaVersion=cu128"
if errorlevel 3 set "cudaVersion=cpu"
if errorlevel 2 if not errorlevel 3 set "cudaVersion=cu126"
Or simpler (since choice returns 1-based index):


choice /c 123 /n /m "Enter choice [1-3]: "
rem choice returns 1,2,3 for characters pressed
if %errorlevel%==3 set "cudaVersion=cpu"
if %errorlevel%==2 set "cudaVersion=cu126"
if %errorlevel%==1 set "cudaVersion=cu128"
To keep the window open and see errors
Add this at the end of your batch file:


pause
Or, if testing inside PowerShell prompt, run:


Start-Process powershell -ArgumentList '-NoExit', '-File', 'install_lada_portable.ps1'
to keep window open.

Recommendation for your case
Since you use inline PowerShell with multiline complexity, consider putting the Powershell script in a separate .ps1 file with variables passed as arguments or environment variables to ease debugging and prevent quoting headaches.

Example calling external script with args:


powershell -NoProfile -ExecutionPolicy Bypass -File "install_lada_portable.ps1" -installPath "%installPath%" -doInstallVS "%doInstallVS%" -cudaVersion "%cudaVersion%"
And inside PowerShell you access parameters:


param(
    [string]$installPath,
    [bool]$doInstallVS,
    [string]$cudaVersion
)
If you want, I can rewrite your entire batch+powershell combo into this external script + simple caller batch that handles user inputs and calls it, simplifying maintenance and debugging.

Summary:

Fix choice errorlevel evaluation order or use %errorlevel% directly.
Add pause at end to avoid window closing.
Consider extracting PowerShell logic to .ps1 script with parameters.
Quote and escape batch variables passed inside PowerShell carefully.
Add error trapping inside PowerShell to print errors for debugging.
If you want me to fix your script fully with these corrections, just say!

yes

Certainly! Below is a two-file setup that correctly handles user input in the batch script and calls a separate PowerShell script with parameters. This keeps things clean, easy to debug, and prevents the quoting issues you experience.

1) Batch launcher file install_lada_portable.bat

@echo off
setlocal EnableExtensions EnableDelayedExpansion

:: Default install path
set "defaultInstallPath=I:\Lada"

:: Prompt for install path
set /p "installPath=Enter install folder path (Default: %defaultInstallPath%): "
if "%installPath%"=="" set "installPath=%defaultInstallPath%"

echo Selected install path: %installPath%

:: Prompt for Visual Studio Build Tools + VCRedist 2013 install
set /p "installVS=Install Visual Studio Build Tools + VC Redist 2013? (y/N): "
if /i "%installVS%"=="y" (set "doInstallVS=true") else set "doInstallVS=false"

:: Prompt for CUDA PyTorch version
echo Select PyTorch CUDA version to install:
echo  1) CUDA 12.8 (recommended)
echo  2) CUDA 12.6
echo  3) CPU-only (no CUDA)
choice /c 123 /n /m "Enter choice [1-3]: "

if %errorlevel%==3 set "cudaVersion=cpu"
if %errorlevel%==2 set "cudaVersion=cu126"
if %errorlevel%==1 set "cudaVersion=cu128"

echo.
echo Starting installation...
echo.

:: Call Powershell script with arguments
powershell -NoProfile -ExecutionPolicy Bypass -File "%~dp0install_lada_portable.ps1" -InstallPath "%installPath%" -DoInstallVS "%doInstallVS%" -CudaVersion "%cudaVersion%"

pause
2) PowerShell install script install_lada_portable.ps1
Save this file in the same folder as the batch launcher.

How to run:
Place both files in the same folder.
Run install_lada_portable.bat as Administrator.
Follow prompts normally.
This setup:

Resolves the batch choice and variable passing issue.
Completely separates complex PowerShell logic to avoid quoting headaches.
Supports passing user choices as parameters safely.
Keeps your install window open after completion with a pause.

Для продолжения нажмите любую клавишу . . .

The error message you get:


Operator "<" is reserved for future use.
RedirectionNotSupported
means PowerShell does not support the < operator for file redirection in this context (unlike bash). You cannot use < to redirect a patch file input like in Linux shells.

How to fix patching commands in PowerShell
You need to either:

Use Get-Content to read the patch file content and pipe it into the patch command, or
Use a cmd.exe shell to perform the patch with redirection (<) if you want to keep it the same.
Recommended fix: use Get-Content and pipe patch input
Replace this in your PowerShell script:


patch -u ../lib/site-packages/ultralytics/utils/ops.py < (Join-Path $patchDir 'increase_mms_time_limit.patch')
with:


Get-Content (Join-Path $patchDir 'increase_mms_time_limit.patch') | patch -u ../lib/site-packages/ultralytics/utils/ops.py -
Note the trailing - tells patch to read patch data from stdin pipe.

Similarly for other patch commands.

So change all 3 patch commands like:

Get-Content (Join-Path $patchDir 'increase_mms_time_limit.patch') | patch -u ../lib/site-packages/ultralytics/utils/ops.py -
Get-Content (Join-Path $patchDir 'remove_ultralytics_telemetry.patch') | patch -u ../lib/site-packages/ultralytics/utils/__init__.py -
Get-Content (Join-Path $patchDir 'fix_loading_mmengine_weights_on_torch26_and_higher.diff') | patch -u ../lib/site-packages/mmengine/runner/checkpoint.py -
Alternative (less recommended):
You can invoke cmd.exe to run the patch commands with redirection:


cmd /c "patch -u ../lib/site-packages/ultralytics/utils/ops.py < `"$patchDir\increase_mms_time_limit.patch`""
But the first method with Get-Content is cleaner and more PowerShelly.

Summary
Change your patch section in install_lada_portable.ps1 to:


$patchDir = Join-Path $ladaDir 'patches'

pushd $venvLadaDir

Get-Content (Join-Path $patchDir 'increase_mms_time_limit.patch') | patch -u ../lib/site-packages/ultralytics/utils/ops.py -
Get-Content (Join-Path $patchDir 'remove_ultralytics_telemetry.patch') | patch -u ../lib/site-packages/ultralytics/utils/__init__.py -
Get-Content (Join-Path $patchDir 'fix_loading_mmengine_weights_on_torch26_and_higher.diff') | patch -u ../lib/site-packages/mmengine/runner/checkpoint.py -

popd
If you want, I can provide the fully corrected script snippet or full script with this fix applied!

yes

Certainly! Below is your corrected patching section for the PowerShell script install_lada_portable.ps1 that uses Get-Content piped into patch as required in PowerShell. This replaces all your previous patch commands using < redirection which is not supported in PowerShell.

Replace this block in your script:

pushd $venvLadaDir
patch -u ../lib/site-packages/ultralytics/utils/ops.py < (Join-Path $patchDir 'increase_mms_time_limit.patch')
patch -u ../lib/site-packages/ultralytics/utils/__init__.py < (Join-Path $patchDir 'remove_ultralytics_telemetry.patch')
patch -u ../lib/site-packages/mmengine/runner/checkpoint.py < (Join-Path $patchDir 'fix_loading_mmengine_weights_on_torch26_and_higher.diff')
popd
With this corrected block:

pushd $venvLadaDir

Get-Content (Join-Path $patchDir 'increase_mms_time_limit.patch') | patch -u ../lib/site-packages/ultralytics/utils/ops.py -
Get-Content (Join-Path $patchDir 'remove_ultralytics_telemetry.patch') | patch -u ../lib/site-packages/ultralytics/utils/__init__.py -
Get-Content (Join-Path $patchDir 'fix_loading_mmengine_weights_on_torch26_and_higher.diff') | patch -u ../lib/site-packages/mmengine/runner/checkpoint.py -

popd
Explanation:
Get-Content <patchfile> reads the patch text.
The pipe | sends this to patch command.
The trailing - in patch -u <target> - tells patch to expect patch input from stdin (the pipe).
This works correctly in PowerShell, unlike the < <file> which is unsupported.
If you want, I can integrate this fully into the complete script I provided before and send you again. Just say!

yes

Certainly! Here is the full updated PowerShell script (install_lada_portable.ps1) incorporating the fixed patching commands using Get-Content | patch ... - and all the previously included logic (editable variables on top, etc.):
