+4.  [Train your Own Models](#train-your-own-models)
+
+### Requirements: software
+1.  Python Virtual Env Setup: All code is implemented in Python but depends on a
+    small number of python packages and a couple of C libraries. We recommend
+    using virtual environment for installing these python packages and python
+    bindings for these C libraries.
+      ```Shell
+      VENV_DIR=venv
+      pip install virtualenv
+      virtualenv $VENV_DIR
+      source $VENV_DIR/bin/activate
+      
+      # You may need to upgrade pip for installing openv-python.
+      pip install --upgrade pip
+      # Install simple dependencies.
+      pip install -r requirements.txt
+
+      # Patch bugs in dependencies.
+      sh patches/apply_patches.sh
+      ```
+
+2.  Install [Tensorflow](https://www.tensorflow.org/) inside this virtual
+    environment. Typically done with `pip install --upgrade tensorflow-gpu`.
+
+3.  Swiftshader: We use
+    [Swiftshader](https://github.com/google/swiftshader.git), a CPU based
+    renderer to render the meshes.  It is possible to use other renderers,
+    replace `SwiftshaderRenderer` in `render/swiftshader_renderer.py` with
+    bindings to your renderer. 
+    ```Shell
+    mkdir -p deps
+    git clone --recursive https://github.com/google/swiftshader.git deps/swiftshader-src
+    cd deps/swiftshader-src && git checkout 91da6b00584afd7dcaed66da88e2b617429b3950
+    mkdir build && cd build && cmake .. && make -j 16 libEGL libGLESv2
+    cd ../../../
+    cp deps/swiftshader-src/build/libEGL* libEGL.so.1
+    cp deps/swiftshader-src/build/libGLESv2* libGLESv2.so.2
+    ```
+
+4.  PyAssimp: We use [PyAssimp](https://github.com/assimp/assimp.git) to load
+    meshes.  It is possible to use other libraries to load meshes, replace
+    `Shape` `render/swiftshader_renderer.py` with bindings to your library for
+    loading meshes. 
+    ```Shell
+    mkdir -p deps
+    git clone https://github.com/assimp/assimp.git deps/assimp-src
+    cd deps/assimp-src
+    git checkout 2afeddd5cb63d14bc77b53740b38a54a97d94ee8
+    cmake CMakeLists.txt -G 'Unix Makefiles' && make -j 16
+    cd port/PyAssimp && python setup.py install
+    cd ../../../..
+    cp deps/assimp-src/lib/libassimp* .
+    ```
+
+5.  graph-tool: We use [graph-tool](https://git.skewed.de/count0/graph-tool)
+    library for graph processing.
+    ```Shell
+    mkdir -p deps
+    # If the following git clone command fails, you can also download the source
+    # from https://downloads.skewed.de/graph-tool/graph-tool-2.2.44.tar.bz2
+    git clone https://git.skewed.de/count0/graph-tool deps/graph-tool-src
+    cd deps/graph-tool-src && git checkout 178add3a571feb6666f4f119027705d95d2951ab
+    bash autogen.sh
+    ./configure --disable-cairo --disable-sparsehash --prefix=$HOME/.local
+    make -j 16
+    make install
+    cd ../../
+    ```
+
+### Requirements: data
+1.  Download the Stanford 3D Inddor Spaces Dataset (S3DIS Dataset) and ImageNet
+    Pre-trained models for initializing different models. Follow instructions in
+    `data/README.md`
+
+### Test Pre-trained Models
+1.  Download pre-trained models using
+    `scripts/scripts_download_pretrained_models.sh`
+
+2.  Test models using `scripts/script_test_pretrained_models.sh`.
+
+### Train Your Own Models
+All models were trained asynchronously with 16 workers each worker using data
+from a single floor. The default hyper-parameters coorespond to this setting.
+See [distributed training with
+Tensorflow](https://www.tensorflow.org/deploy/distributed) for setting up
+distributed training. Training with a single worker is possible with the current
+code base but will require some minor changes to allow each worker to load all
+training environments.
+
+### Contact
+For questions or issues open an issue on the tensorflow/models [issues
+tracker](https://github.com/tensorflow/models/issues). Please assign issues to
+@s-gupta.

+This directory contains the data needed for training and benchmarking various
+navigation models.
+
+1.  Download the data from the [dataset website]
+    (http://buildingparser.stanford.edu/dataset.html).
+    1.  [Raw meshes](https://goo.gl/forms/2YSPaO2UKmn5Td5m2). We need the meshes
+        which are in the noXYZ folder. Download the tar files and place them in
+        the `stanford_building_parser_dataset_raw` folder. You need to download
+        `area_1_noXYZ.tar`, `area_3_noXYZ.tar`, `area_5a_noXYZ.tar`,
+        `area_5b_noXYZ.tar`, `area_6_noXYZ.tar` for training and
+        `area_4_noXYZ.tar` for evaluation.
+    2.  [Annotations](https://goo.gl/forms/4SoGp4KtH1jfRqEj2) for setting up
+        tasks. We will need the file called `Stanford3dDataset_v1.2.zip`. Place
+        the file in the directory `stanford_building_parser_dataset_raw`.
+
+2.  Preprocess the data.
+    1.  Extract meshes using `scripts/script_preprocess_meshes_S3DIS.sh`. After
+        this `ls data/stanford_building_parser_dataset/mesh` should have 6
+        folders `area1`, `area3`, `area4`, `area5a`, `area5b`, `area6`, with
+        textures and obj files within each directory.
+    2.  Extract out room information and semantics from zip file using
+        `scripts/script_preprocess_annoations_S3DIS.sh`. After this there should
+        be `room-dimension` and `class-maps` folder in
+        `data/stanford_building_parser_dataset`. (If you find this script to
+        crash because of an exception in np.loadtxt while processing
+        `Area_5/office_19/Annotations/ceiling_1.txt`, there is a special
+        character on line 323474, that should be removed manually.)
+
+3.  Download ImageNet Pre-trained models. We used ResNet-v2-50 for representing
+    images. For RGB images this is pre-trained on ImageNet. For Depth images we
+    [distill](https://arxiv.org/abs/1507.00448) the RGB model to depth images
+    using paired RGB-D images. Both there models are available through
+    `scripts/script_download_init_models.sh`
