Synthesis of Compositional Animations from Textual Descriptions (ICCV 2021)

[Paper], [Video]

Our code is tested on the following OS:

• Ubuntu 18.04 LTS
• Windows 10

Pre-requisites

Code

• Python >= 3.6.10
• Pytorch >= 1.5.1
• conda >= 4.9.2 (optional but recommended)

All other pre-requisites are in the file environment.yml. Steps to install:

1. Create the conda environment:

conda env create -f environment.yml
conda activate text2motion

2. Install pytorch following the official instructions.

3. Install all other requirements:

pip install -r requirements.txt

We denote the base directory of our project as $BASE.

Data

Download the KIT Motion-Language dataset and unzip the files in the $BASE/dataset/kit-mocap folder.

Running the code

1. First, run: cd $BASE/src

2. Preprocessing the data: python data.py This will create quat.csv, fke.csv and rifke.csv files for each input data.

3. Calculate the mean and variance for Z-Normalization: python dataProcessing/meanVariance.py -mask '[0]' -feats_kind rifke -dataset KITMocap -path2data ../dataset/kit-mocap -f_new 8 The outputs will be saved in $BASE/src/dataProcessing/meanVar.

4. [Optional] Train the model: python train_model_GD.py -batch_size 32 -curriculum 0 -dataset KITMocap -early_stopping 1 -exp 1 -f_new 8 -feats_kind rifke -lr 0.001 -mask "[0]" -model hierarchical_twostream -cpk t2m -num_epochs 300 -path2data ../dataset/kit-mocap -render_list subsets/render_list -s2v 1 -save_dir save/model -tb 1 -time 32 -transforms "['zNorm']"

We also provide a pre-trained model here. To use it, extract the contents of the downloaded zip file pretrained_model.zip inside the folder $BASE/src/save/model.

5. Testing the trained model: python sample_wordConditioned.py -load save/model/$weights where $weights is the pre-trained network parameters, saved as a .p file. The outputs are generated inside a folder $BASE/src/save/model/$OUTPUT created automatically.

6. Calculating the error metrics:

python eval_APE.py -load save/model/$weights
python eval_AVE.py -load save/model/$weights
python eval_CEE_SEE.py -load save/model/$weights

7. Rendering the output files: python render.py -dataset KITMocap -path2data ../dataset/kit-mocap -feats_kind rifke -clean_render 0 -save_dir save/model/$OUTPUT
