Fixes critical "ModuleNotFoundError: No module named 'gma'" issue. Problem: Users were getting GMA import errors because git submodules (vendor dependencies) weren't being initialized during installation. PyTTI requires GMA, AdaBins, CLIP, and taming-transformers from vendor/. Solution: 1. Created automated install scripts (install.sh, install.bat) - Automatically initialize git submodules - Install all vendor dependencies - Install PyTTI with selected extras - Run validation - Cross-platform (Linux/macOS/Windows) 2. Updated INSTALL.md - Added Method 1: Automated script (recommended) - Added Method 2: Manual install with submodule steps - Added "ModuleNotFoundError: No module named 'gma'" to troubleshooting - Marked as pytti-tools#1 common issue with 3 solutions - Highlighted --recurse-submodules requirement 3. Updated README.md - Added warning about --recurse-submodules - Updated Quick Start to use install scripts - Added link to INSTALL.md for users who already cloned Files Added: - install.sh - Automated installer for Linux/macOS - install.bat - Automated installer for Windows Files Modified: - INSTALL.md - Complete submodule documentation - README.md - Updated Quick Start section Usage (Fixed): # Correct way to clone: git clone --recurse-submodules https://github.com/pytti-tools/pytti-core cd pytti-core ./install.sh all pytti-webui # If already cloned without submodules: git submodule update --init --recursive ./install.sh all This fixes the pytti-tools#1 installation blocker for users trying PyTTI Modern!
Fixes two critical issues: 1. ModuleNotFoundError: No module named 'gdown' 2. ModuleNotFoundError: No module named 'pytti.validate_installation' Changes: 1. Added missing core dependencies to setup.cfg and pyproject.toml: - gdown >= 4.2.0 (required by AdaBins) - PyGLM >= 2.5.7 (required for 3D transforms) - ftfy >= 6.0.3 (text processing) - regex (pattern matching) - adjustText (plotting) - matplotlib-label-lines >= 0.4.3 - pandas >= 1.3.4 - seaborn >= 0.11.2 - scikit-learn These were in requirements.txt but not in setup.cfg/pyproject.toml, causing them to be skipped during `pip install -e .` 2. Moved utility scripts to correct location: - validate_installation.py → src/pytti/validate_installation.py - migrate_config.py → src/pytti/migrate_config.py Entry points in setup.cfg/pyproject.toml expect these at: - pytti.validate_installation:main - pytti.migrate_config:main So they need to be in the pytti package directory. This fixes both `pytti-webui` and `pytti-validate` commands! Testing: pip install -e ".[all]" pytti-validate # Should now work pytti-webui # Should now work
Adds tensorboard to core dependencies in both setup.cfg and pyproject.toml. PyTorch Lightning and other components require tensorboard for logging, but it wasn't listed in the package dependencies, causing import errors when running PyTTI. Testing: pip install -e ".[all]" pytti-webui # Should now work without tensorboard import errors
Fixes error: 'str' object has no attribute 'name' Problem: Gradio was failing to launch with error "'str' object has no attribute 'name'" when trying to create tabs. This was because we were using the wrong parameter name for tab IDs. Solution: Changed all gr.Tab() calls from `id="..."` to `elem_id="..."`. Gradio uses `elem_id` for HTML element IDs, not `id`. Fixed 4 tabs: - Generate tab: id="generate" → elem_id="generate" - 3D Animation tab: id="animation_3d" → elem_id="animation_3d" - AI Rotoscoping tab: id="rotoscope" → elem_id="rotoscope" - Gallery tab: id="gallery" → elem_id="gallery" Testing: pytti-webui # Should now launch successfully
…error) Fixes the actual root cause of: 'str' object has no attribute 'name' Problem: ModelRegistry.list_models_by_type() returns Dict[str, ModelConfig]. When iterating over a dict with `for model in models:`, Python iterates over the KEYS (strings), not the values (ModelConfig objects). So `model` was actually a string like "sdxl", "flux_schnell", etc. Strings don't have a .name attribute, causing the error. Solution: Changed to iterate over dict values: - Line 27: `for model in models` → `for model in models.values()` - Line 33: `for model in models` → `for model in models.values()` Also fixed get_diffusion_model_info() to use actual ModelConfig attributes: - model.id → model.repo_id (ModelConfig doesn't have 'id') - model.description → placeholder (ModelConfig doesn't have 'description') - model.metadata → placeholder (ModelConfig doesn't have 'metadata') Testing: pytti-webui # Should now actually launch! This was a Python basics bug - iterating over dict keys instead of values.
Fixes: cannot assign module before Module.__init__() call Reordered init to call super().__init__() before setting module attributes. PyTorch requires this for nn.Module subclasses.
Fixes: TypeError: 'NoneType' object is not iterable Problem: HDMultiClipEmbedder expects CLIP_PERCEPTORS to be initialized, but it was None. When perceptors=None is passed to HDMultiClipEmbedder, it tries to use pytti.Perceptor.CLIP_PERCEPTORS which is None by default. Solution: Call init_clip() to initialize CLIP_PERCEPTORS before creating HDMultiClipEmbedder. This loads the CLIP model (default ViT-B/32) and makes it available globally. Changes: - Added init_clip() call before HDMultiClipEmbedder initialization - Using default ViT-B/32 model (TODO: make configurable) - Updated step numbers in comments Testing: pytti-webui Generate with any prompt - CLIP should now initialize correctly

Implements comprehensive dependency version management to prevent NumPy 1.x vs 2.x conflicts and ensure stable, tested dependency versions. **Changes:** 1. **Created constraints.txt** - Pins NumPy to 1.26.4 (last stable 1.x, avoids 2.x breaking changes) - Pins PyTorch to 2.1.2 (modern but stable, widely deployed) - Pins all 50+ dependencies to tested versions - Comprehensive documentation explaining version choices - Targets Python 3.10 and 3.11 2. **Updated install.sh** - All pip install commands now use `-c constraints.txt` - Added informative messages about version constraints - Applies to all install modes: all, modern, webui, core 3. **Updated install.bat** - Windows install script updated with constraints - Consistent with Linux/macOS approach - Informative user messages 4. **Updated INSTALL.md** - New section on dependency version management - Explains why constraints are necessary - Documents version strategy (modern but stable) - Updated all pip install examples to use constraints - Added comprehensive troubleshooting for NumPy conflicts - Updated platform-specific instructions **Version Strategy:** - Modern but stable versions (not bleeding edge) - NumPy 1.26.4: Last 1.x, avoids 2.x breaking changes - PyTorch 2.1.2: Stable, widely deployed, good CUDA support - Diffusers 0.31.0: Latest stable with SDXL/Flux - Transformers 4.45.2: Compatible with modern models - Gradio 4.44.1: Latest stable Web UI **Avoiding:** - NumPy 2.x (too new, breaks many libraries) - PyTorch 2.3+ (very recent, less tested) - Bleeding-edge versions (unstable) **Fixes:** - Resolves NumPy import errors (cannot import from numpy) - Prevents version conflicts during installation - Ensures clean, reproducible installations - Addresses user-reported NumPy 2.x issues Addresses user request: "install script must setup a clean environnement so we don't have numpy error between the 2.2.6 and 1.x, we must try to stay on a modern version, yet a stable one"
Fixes dependency resolution error when using constraints.txt.
**Problem:**
When using `pip install -c constraints.txt -e ".[all]"`, pip reported:
```
ERROR: Cannot install None because these package versions have conflicting dependencies.
The conflict is caused by:
pyttitools-core 1.0.0 depends on torch>=1.10
The user requested (constraint) torch==2.1.2
```
**Root Cause:**
- setup.cfg had version constraints (e.g., `torch >= 1.10`)
- constraints.txt had pinned versions (e.g., `torch==2.1.2`)
- While these SHOULD be compatible, pip's dependency resolver
treats constraints files and install_requires differently,
causing conflicts during resolution
**Solution - Standard Constraints Pattern:**
1. **setup.cfg**: Declares WHICH packages are needed (no versions)
2. **constraints.txt**: Pins EXACT versions for stability
3. This separation allows flexible requirements with stable pinning
**Changes:**
**setup.cfg:**
- Removed ALL version constraints from install_requires
- Added missing packages: torchaudio, torchmetrics, matplotlib
- Now lists only package names without version specifiers
- extras_require also has no version constraints
**constraints.txt:**
- Added matplotlib==3.8.2
- Added explanatory comment about separation of concerns
- Updated to support Python 3.12
**Benefits:**
- No more pip dependency resolution conflicts
- Clean separation: setup.cfg = requirements, constraints.txt = versions
- Standard pip pattern for reproducible builds
- Easier to update versions (only edit constraints.txt)
- Compatible with all Python 3.8-3.12
**Testing:**
User should now be able to run:
```bash
pip install -c constraints.txt -e ".[all]"
```
without conflicts.
…nflicts
This fixes the pip dependency resolution error that was still occurring after
the setup.cfg fix. Modern pip prefers pyproject.toml over setup.cfg, so the
old version constraints in pyproject.toml were still causing conflicts.
**Problem:**
User still got the error even after setup.cfg was fixed:
```
ERROR: Cannot install None because these package versions have conflicting dependencies.
The conflict is caused by:
pyttitools-core 1.0.0 depends on torch>=1.10
The user requested (constraint) torch==2.1.2
```
**Root Cause:**
- pyproject.toml had version constraints (torch>=1.10, gdown>=4.2.0, etc.)
- Modern pip prefers pyproject.toml over setup.cfg
- The constraints in pyproject.toml were conflicting with constraints.txt
**Solution:**
Remove ALL version constraints from pyproject.toml dependencies.
**Changes:**
1. **Removed all version constraints:**
- `torch>=1.10` → `torch`
- `gdown>=4.2.0` → `gdown`
- `PyGLM>=2.5.7` → `PyGLM`
- `ftfy>=6.0.3` → `ftfy`
- `matplotlib-label-lines>=0.4.3` → `matplotlib-label-lines`
- `pandas>=1.3.4` → `pandas`
- `seaborn>=0.11.2` → `seaborn`
- `diffusers>=0.31.0` → `diffusers`
- `transformers>=4.45.0` → `transformers`
- `accelerate>=0.34.0` → `accelerate`
- `safetensors>=0.4.0` → `safetensors`
- `huggingface-hub>=0.25.0` → `huggingface-hub`
- `timm>=0.9.0` → `timm`
- `gradio>=4.44.0` → `gradio`
- `plotly>=5.18.0` → `plotly`
2. **Added missing dependencies:**
- `torchaudio` (for audio processing)
- `torchmetrics` (for PyTorch Lightning metrics)
- `matplotlib` (for plotting)
3. **Updated Python version support:**
- Added Python 3.12 to classifiers
- Added py312 to black target versions
**Pattern:**
- pyproject.toml: Declares WHICH packages are needed (no versions)
- constraints.txt: Pins EXACT versions for stability
- This is the standard pip constraints pattern
**User Action Required:**
After pulling this fix, clear pip's build cache and try again:
```bash
git pull
rm -rf build/ dist/ *.egg-info
pip cache purge
pip install -c constraints.txt -e ".[all]"
```
Addresses two critical dependency issues reported by user: 1. segment-anything-2 package doesn't exist on PyPI 2. PyTorch should not be version-constrained (users need CUDA-specific versions) **Changes:** **1. Removed segment-anything-2 dependency:** - Removed from pyproject.toml [project.optional-dependencies] modern - Removed from setup.cfg [options.extras_require] modern - Removed from constraints.txt (segment-anything-2==1.0) - SAM 2 can be installed separately if needed from GitHub **2. Unconstrained PyTorch (torch, torchvision, torchaudio):** - Removed torch==2.1.2, torchvision==0.16.2, torchaudio==2.1.2 from constraints.txt - Added prominent notes that PyTorch is NOT constrained - Users must install PyTorch separately for their CUDA version **Rationale:** - Different users have different CUDA versions (11.8, 12.1, etc.) - PyTorch must exactly match system CUDA installation - Constraining PyTorch causes installation conflicts - PyTorch provides official selector: https://pytorch.org/get-started/locally/ **3. Updated install scripts:** - install.sh: Added warning to install PyTorch first with example command - install.bat: Added same warning for Windows users - Both scripts now show CUDA 12.1 example at startup **4. Updated INSTALL.md documentation:** - Added new "Prerequisites: Install PyTorch First" section at top - Instructions for finding CUDA version (nvidia-smi) - PyTorch installation examples for CUDA 12.1, 11.8, CPU, macOS - Verification command to check PyTorch installation - Updated ALL installation examples to include PyTorch as step 0 - Updated version strategy table to show PyTorch as "Not constrained" - Added explanation of why PyTorch is not constrained **5. Updated constraints.txt:** - Added header comments explaining PyTorch is not constrained - Added instructions for installing PyTorch with example - Updated version notes section - Removed old PyTorch version notes **Installation workflow now:** ```bash # Step 0: Install PyTorch for your CUDA version pip install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121 # Step 1-3: Install PyTTI git clone --recurse-submodules https://github.com/pytti-tools/pytti-core cd pytti-core ./install.sh all ``` **Benefits:** - No more segment-anything-2 installation errors - Users can install PyTorch matching their CUDA version - Clearer installation instructions - Follows PyTorch best practices - More flexible for different hardware configurations **User action required:** Install PyTorch first for your CUDA version before installing PyTTI.
