Progressive Dependency Loading + +When ComfyUI loads the node, this process occurs: +1. Basic dependencies are checked (torch, numpy, etc.) +2. Advanced dependencies are attempted (pytorch3d, roma, etc.) +3. The appropriate implementation is selected: + - If all dependencies are available: Full implementation is used + - If any dependencies are missing: Simplified implementation is used + +### 3. Node Registration + +Two nodes are available based on the dependency situation: +- **LHM Human Reconstruction**: Always available, with functionality level based on dependencies +- **LHM Test Node**: Available in simplified mode, helps verify basic functionality + +## Common Issues and Solutions + +### Issue: Node doesn't appear in ComfyUI +**Solution:** +- Check ComfyUI logs for import errors +- Verify if node is using simplified implementation +- Install missing dependencies + +### Issue: "ModuleNotFoundError: No module named 'pytorch3d'" +**Solution:** +- This complex dependency is optional. Without it, the simplified implementation will be used + +- **Option 1 (Highly Recommended): Direct Installation from Source (Official Method):** + + Following the [official PyTorch3D installation guide](https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md), we've had success with: + ```bash + # First, ensure PyTorch and torchvision are properly installed with MPS support + python -m pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cpu + + # Verify MPS support + python -c "import torch; print(f'PyTorch: {torch.__version__}, MPS available: {torch.backends.mps.is_available()}')" + + # Install prerequisites + python -m pip install fvcore iopath + + # For macOS with Apple Silicon (M1/M2/M3) + MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python -m pip install -e "git+https://github.com/facebookresearch/pytorch3d.git@stable" + + # Or clone and install from source + git clone https://github.com/facebookresearch/pytorch3d.git + cd pytorch3d + MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python -m pip install -e . + ``` + The key for Apple Silicon success is setting the environment variables `MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++`. + +- **Option 2 (Reliable): Use conda to install PyTorch3D:** + ```bash + # Using the bash script + cd ~/Desktop/LHM/comfy_lhm_node + chmod +x install_pytorch3d_conda.sh + ./install_pytorch3d_conda.sh + + # Or using the Python script + cd ~/Desktop/LHM/comfy_lhm_node + chmod +x install_pytorch3d_conda.py + ./install_pytorch3d_conda.py + ``` + This method handles complex dependencies better than pip. + +- **Option 3: Use our specially optimized PyTorch MPS installation:** + ```bash + cd ~/Desktop/LHM/comfy_lhm_node + chmod +x install_pytorch_mps.py + ./install_pytorch_mps.py + ``` + +- **Option 4: Use our specially optimized PyTorch3D installation scripts for Apple Silicon:** + ```bash + # Using the bash script + cd ~/Desktop/LHM/comfy_lhm_node + chmod +x install_pytorch3d_mac.sh + ./install_pytorch3d_mac.sh + + # Or using the Python script + cd ~/Desktop/LHM/comfy_lhm_node + chmod +x install_pytorch3d_mac.py + ./install_pytorch3d_mac.py + ``` + +- **Option 5: Use PyTorch3D-Lite as an alternative (easier installation):** + ```bash + cd ~/Desktop/LHM/comfy_lhm_node + chmod +x install_pytorch3d_lite.py + ./install_pytorch3d_lite.py + ``` + This will install a simplified version of PyTorch3D with fewer features, but it's much easier to install and works on most systems including Apple Silicon. + +- **Option 6: Manual installation (advanced):** + - For Apple Silicon Macs: + ```bash + MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python -m pip install pytorch3d + ``` + - For other systems, see the [pytorch3d installation documentation](https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md) + +### Issue: "ModuleNotFoundError: No module named 'roma'" +**Solution:** +- Install roma: + ```bash + python -m pip install roma + ``` +- Without this, the simplified implementation will be used + +### Issue: "ModuleNotFoundError: No module named 'onnxruntime'" +**Solution:** +- Install the correct onnxruntime for your system: + ```bash + # For Apple Silicon Macs (M1/M2/M3) + python -m pip install onnxruntime-silicon + + # For other systems + python -m pip install onnxruntime + ``` + +### Issue: Model weights not found +**Solution:** +- Ensure you've run the download_weights.sh script +- If the script fails, manually download the weights +- Create symbolic links to the weights: + ```bash + ln -s ~/path/to/your/LHM/checkpoints/*.pth ~/pinokio/api/comfy.git/app/models/checkpoints/ + ``` + +### Issue: "pip: command not found" or similar errors +**Solution:** +- Use the full path to the Python interpreter: + ```bash + ~/pinokio/api/comfy.git/app/env/bin/python -m pip install package_name + ``` +- Alternatively, activate the virtual environment first: + ```bash + source ~/pinokio/api/comfy.git/app/env/bin/activate + ``` + +## Special Instructions for Apple Silicon (M1/M2/M3) Macs + +If you're using an Apple Silicon Mac (M1, M2, or M3), you may encounter specific challenges with PyTorch3D. We've developed several solutions to address this: + +### 1. Official PyTorch3D Installation (Most Reliable) + +The [official PyTorch3D installation guide](https://github.com/facebookresearch/pytorch3d/blob/main/INSTALL.md) provides specific instructions for Apple Silicon Macs that we've verified work: + +```bash +# First ensure you have the appropriate compilers and PyTorch installed +python -m pip install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cpu + +# Install from GitHub with the correct environment variables +MACOSX_DEPLOYMENT_TARGET=10.9 CC=clang CXX=clang++ python -m pip install -e "git+https://github.com/facebookresearch/pytorch3d.git@stable" +``` + +The critical factors for successful installation on Apple Silicon are: +- Setting `MACOSX_DEPLOYMENT_TARGET=10.9` +- Using clang as the compiler with `CC=clang CXX=clang++` +- Installing from source (either via git or by cloning the repository) +- Using PyTorch with MPS support enabled + +After installation, you can verify it works by running: +```bash +python -c "import pytorch3d; print(f'PyTorch3D version: {pytorch3d.__version__}')" +``` + +### 2. Conda-Based PyTorch3D Installation (Alternative Approach) + +### 3. Optimized PyTorch + MPS + PyTorch3D Installation + +The most reliable solution is to use our combined installation script that: +- Installs PyTorch with proper MPS (Metal Performance Shaders) support +- Installs PyTorch3D from a compatible source build +- Sets up PyTorch3D-Lite as a fallback + +```bash +cd ~/Desktop/LHM/comfy_lhm_node +chmod +x install_pytorch_mps.py +./install_pytorch_mps.py +``` + +This script verifies that MPS is available and correctly configured before proceeding with the PyTorch3D installation, resulting in better performance and compatibility. + +### 4. PyTorch3D Full Installation + +The `install_pytorch3d_mac.sh` and `install_pytorch3d_mac.py` scripts automate the complex process of installing PyTorch3D on Apple Silicon. These scripts: + +- Set the necessary environment variables for compilation +- Find your Pinokio ComfyUI Python installation +- Install prerequisites (fvcore, iopath, ninja) +- Clone the PyTorch3D repository and check out a compatible commit +- Build and install PyTorch3D from source +- Install roma which is also needed for LHM + +### 4. PyTorch3D-Lite Alternative + +If you encounter difficulties with the full PyTorch3D installation, we provide a lightweight alternative: + +- The `install_pytorch3d_lite.py` script installs pytorch3d-lite and creates the necessary compatibility layer +- This version has fewer features but works on most systems without complex compilation +- It provides the core functionality needed for the LHM node + +### 5. Solving Animation Format Errors + +If you have the error with animation outputs like `TypeError: ... (1, 1, 400, 3), |u1`, you can: + +1. **Add a Tensor Reshape node:** + - Disconnect the animation output from any Preview Image node + - Add a "Tensor Reshape" node from ComfyUI + - Connect the LHM animation output to the Tensor Reshape input + - Set the custom shape in the Tensor Reshape node to `-1, -1, 3` + - Connect the Tensor Reshape output to your Preview Image node + +2. **Update to Full Implementation:** + - Run one of our PyTorch3D installation scripts + - Restart ComfyUI + - The full implementation will handle the animation output correctly + +## Checking Installation Success + +After running any of the PyTorch3D installation scripts, verify your installation: + +1. Restart ComfyUI in Pinokio +2. Check the ComfyUI logs for these messages: + - "Using conda-installed PyTorch3D" indicates success with the conda method + - "Successfully loaded full LHM implementation" indicates success with direct installation + - "PyTorch3D-Lite fix loaded successfully" indicates the lite version is working + - "Using simplified implementation" indicates installation issues persist + +## Testing the Installation + +To verify your installation, follow these steps: + +1. **Check which implementation is active** + Open the ComfyUI logs and look for one of these messages: + - "Successfully loaded full LHM implementation" (full functionality available) + - "Using simplified implementation - some functionality will be limited" (fallback mode active) + +2. **Use the LHM Test Node** + - Add the "LHM Test Node" to your workflow + - Connect an image source to it + - Choose the "Add Border" option to verify processing + - Run the workflow - a green border should appear around the image + +3. **Use the LHM Human Reconstruction Node** + - Connect an image source to the LHM Human Reconstruction node + - Run the workflow + - In simplified mode, you'll get a basic animation output + - In full mode, you'll get proper 3D reconstruction and animation + +## Working Towards Full Functionality + +To enable full functionality if the simplified implementation is active: + +1. **Check which dependencies are missing** + Look at the ComfyUI logs for specific import errors + +2. **Install all required dependencies**: + ```bash + ~/pinokio/api/comfy.git/app/env/bin/python -m pip install omegaconf rembg opencv-python scikit-image matplotlib roma + ``` + +3. **Install pytorch3d** (if needed): + ```bash + #
