LoRA Dataset Studio V2

V2 is the maintained LDS release. Existing ZIP installations can upgrade from Settings → Maintenance → Update & restart, keeping datasets, media and history. Git installations still on the former main branch must first switch to v2. Optional features are plugins: open Plugins → Store after updating, install the ones you use and review their settings before the first run.

Install the core, then choose your plugins

Download LoRA-Dataset-Studio-windows.zip below, extract it into a new folder and double-click start.bat. The launcher prepares a compatible Python environment. Complete the core Setup, then open Plugins → Store to install the features you want. Each plugin has its own settings and preparation steps, including required ComfyUI custom nodes. Importing and organising datasets does not require a plugin.

Free public plugins are available through the Store. Each plugin describes its features and preparation requirements. Paid API engines and rented GPUs still charge separately when you choose to use them.

The core and these public plugins are available at no charge, with their source published under the project's PolyForm Noncommercial license. New LDS versions reach Patreon members (LDS Member) first, then everyone, and some plugins are members-only; the version you have stays free and keeps working. Usage statistics are optional and off by default; the app asks before sharing, and you can change your choice in Settings → Maintenance.

Two ways to install and update

ZIP installations: Update & restart installs the next published release, preserving your data and local configuration. The ZIP below contains the core; plugins are installed and updated separately through the Store.

Git installations: v2 is the default and maintained branch. Update & restart follows the commits of your checkout's configured branch. The former main branch is now the frozen v1 branch; it receives no further updates. Follow the migration instructions if your checkout still tracks main.

The diagnostic report copies in Firefox

In Firefox, 📋 Copy diagnostic report could fail with "Clipboard write was blocked due to lack of user activation" when the report took more than a few seconds to build. The copy now starts with your click and finishes once the report is ready. If a browser still refuses, the report appears under the button so you can copy it by hand.

start.bat works from a PowerShell 7 prompt

Launched from PowerShell 7, start.bat could not fetch its own Python ("Get-FileHash is not recognized") and warned that the ML extras would not install. The download now works from any prompt, and a Python 3.10–3.12 already on your PATH is used as is, even without the py launcher.

A negative prompt for Krea test runs above CFG 1

The Test Studio offered no negative prompt for Krea, even on a Raw base that samples at CFG 4, where it changes the image. The Negative section now appears as soon as a Krea run uses a CFG above 1. At CFG 1 the sampler ignores it.

Your Bank shows HEIC and AVIF photos too

A Bank over a folder of iPhone photos or AVIF images used to skip them. They are now inventoried, shown, scored, face-sorted and promoted like any other image, through a lossless PNG copy the app keeps in its own data folder. Your files are never touched.

iPhone photos (HEIC) and AVIF images import into your datasets

HEIC/HEIF photos and AVIF images were refused at import. They now import from the dropzone, a ZIP or a folder, with or without auto head-crop, and work as a reference too. The trainers cannot read them, so the default original-file mode keeps each one as a lossless PNG.

A queued training that cannot start says why

When a training waiting in the queue failed to start when its turn came, it left the queue without a word. The Training panel now names it and gives the reason.

A queued training waits for the GPU instead of vanishing

A training in the queue could disappear when its turn came while ComfyUI was generating or a vision pass held the GPU. It now keeps its place, the queue says what it is waiting for, and it starts on its own once the GPU is free.

A stopped local training keeps its checkpoints in Runs

Stopping a local training showed it as a crash, with an error and ↻ Retry, and the Runs page offered no ◉ Graph for a local run on its own. A Stop now reads as a stop, and every local run opens its ◉ Graph with the checkpoints it saved.
