📢 2024-08-02 --- The WebUI demo 🤗 is now running smoothly on a CPU. No GPU is required to use MoMask.
📢 2024-02-26 --- 🔥🔥🔥 Congrats! MoMask is accepted to CVPR 2024.
📢 2024-01-12 --- Now you can use MoMask in Blender as an add-on. Thanks to @makeinufilm for sharing the tutorial.
📢 2023-12-30 --- For easy WebUI BVH visulization, you could try this website bvh2vrma from this github.
📢 2023-12-29 --- Thanks to Camenduru for supporting the 🤗Colab demo.
📢 2023-12-27 --- Release WebUI demo. Try now on 🤗HuggingFace!
📢 2023-12-19 --- Release scripts for temporal inpainting.
📢 2023-12-15 --- Release codes and models for momask. Including training/eval/generation scripts.
📢 2023-11-29 --- Initialized the webpage and git project.
conda env create -f environment.yml
conda activate momask
pip install git+https://github.com/openai/CLIP.git
We test our code on Python 3.7.13 and PyTorch 1.7.1
pip install -r requirements.txt
We test this installation on Python 3.10
bash prepare/download_models.sh
For evaluation only.
bash prepare/download_evaluator.sh
bash prepare/download_glove.sh
To address the download error related to gdown: "Cannot retrieve the public link of the file. You may need to change the permission to 'Anyone with the link', or have had many accesses". A potential solution is to run pip install --upgrade --no-cache-dir gdown, as suggested on wkentaro/gdown#43. This should help resolve the issue.
Visit [Google Drive] to download the models and evaluators mannually.
You have two options here:
- Skip getting data, if you just want to generate motions using own descriptions.
- Get full data, if you want to re-train and evaluate the model.
(a). Full data (text + motion)
HumanML3D - Follow the instruction in HumanML3D, then copy the result dataset to our repository:
cp -r ../HumanML3D/HumanML3D ./dataset/HumanML3D
KIT-Download from HumanML3D, then place result in ./dataset/KIT-ML
python gen_t2m.py --gpu_id 1 --ext exp1 --text_prompt "A person is running on a treadmill."
An example of prompt file is given in ./assets/text_prompt.txt. Please follow the format of <text description>#<motion length> at each line. Motion length indicates the number of poses, which must be integeter and will be rounded by 4. In our work, motion is in 20 fps.
If you write <text description>#NA, our model will determine a length. Note once there is one NA, all the others will be NA automatically.
python gen_t2m.py --gpu_id 1 --ext exp2 --text_path ./assets/text_prompt.txt
A few more parameters you may be interested:
--repeat_times: number of replications for generation, default1.--motion_length: specify the number of poses for generation, only applicable in (a).
The output files are stored under folder ./generation/<ext>/. They are
numpy files: generated motions with shape of (nframe, 22, 3), under subfolder./joints.video files: stick figure animation in mp4 format, under subfolder./animation.bvh files: bvh files of the generated motion, under subfolder./animation.
We also apply naive foot ik to the generated motions, see files with suffix _ik. It sometimes works well, but sometimes will fail.
All the animations are manually rendered in blender. We use the characters from mixamo. You need to download the characters in T-Pose with skeleton.
For retargeting, we found rokoko usually leads to large error on foot. On the other hand, keemap.rig.transfer shows more precise retargetting. You could watch the tutorial here.
Following these steps:
- Download keemap.rig.transfer from the github, and install it in blender.
- Import both the motion files (.bvh) and character files (.fbx) in blender.
Shift + Selectthe both source and target skeleton. (Do not need to be Rest Position)- Switch to
Pose Mode, then unfold theKeeMapRigtool at the top-right corner of the view window. - For
bone mapping file, direct to./assets/mapping.json(ormapping6.jsonif it doesn't work), and clickRead In Bone Mapping File. This file is manually made by us. It works for most characters in mixamo. - (Optional) You could manually fill in the bone mapping and adjust the rotations by your own, for your own character.
Save Bone Mapping Filecan save the mapping configuration in local file, as specified by the mapping file path. - Adjust the
Number of Samples,Source Rig,Destination Rig Name. - Clik
Transfer Animation from Source Destination, wait a few seconds.
We didn't tried other retargetting tools. Welcome to comment if you find others are more useful.
We use this scene for animation.
python edit_t2m.py --gpu_id 1 --ext exp3 --use_res_model -msec 0.4,0.7 --text_prompt "A man picks something from the ground using his right hand."
Note: Presently, the source motion must adhere to the format of a HumanML3D dim-263 feature vector. An example motion vector data from the HumanML3D test set is available in example_data/000612.npy. To process your own motion data, you can utilize the process_file function from utils/motion_process.py.
Note: You have to train RVQ BEFORE training masked/residual transformers. The latter two can be trained simultaneously.
You may also need to download evaluation models to run the scripts.
