TL;DR

This repo migrate the following work to Python3 and latest PyTorch [v1.3]:

  1. Learning Category-Specific Mesh Reconstruction from Image Collections (ECCV 2018)
  2. Neural 3D Mesh Renderer (CVPR 2018)

Special thanks to the them and neural_renderer_pytorch.

What's new here:

  • update the code [Python2 -> Python3, PyTorch 0.x -> PyTorch 1.3].
  • Remove Chainer/Cupy dependancy (Chainer is depreciated and it's painful to install cupy).
  • Simplify the environment setup.
  • Slightly reorg and simplify the code.

Neural Render

CMR

Requirements

  • Python 3 [Python2 may work as well]
  • PyTorch tested on version 1.3.0

Installation

Setup python

conda create -n cmr python=3
conda activate cmr
conda install pytorch torchvision -c pytorch
pip install -r requirements.txt

install neural_renderer

export CUDA_HOME=/path/to/cuda/

Install CUDA here with the same version as PyTorch python -c 'import torch;print(torch.version.cuda)'. You may skip it if you alreadly have it in your machine.

Make sure you set the right CUDA_HOME (e.g. ls $CUDA_HOME/bin/nvcc works.) and then build extension

python setup.py install # install to sys.path
python setup.py build develop # install to workspace

Demo

  1. From the cmr directory, download the trained model:
cd misc && wget https://people.eecs.berkeley.edu/~kanazawa/cachedir/cmr/model.tar.gz && tar -vzxf model.tar.gz && cd ..

You should see misc/cachedir/snapshots/bird_net/

  1. Run the demo:
python demo.py --name bird_net --num_train_epoch 500 --img_path misc/demo_data/img1.jpg
python demo.py --name bird_net --num_train_epoch 500 --img_path misc/demo_data/birdie.jpg

Training

Please see train.md
