Smplify-X-Perfect-Implementation

Smplify-X implementation. (2024. 03. 18 No Error & Recent version)
🚶🏻‍♂️Quick start(colab):

I modified 🌟SMPLpix code. Please check!

Code Overview

gender = 'female' #@param ["neutral", "female", "male"]

!rm -rf /content/data/smplifyx_results
%cd /content/Smplify-X-Perfect-Implementation
!git pull origin

!python smplifyx/main.py --config cfg_files/fit_smplx.yaml \
    --data_folder  /content/data \
    --output_folder /content/data/smplifyx_results \
    --visualize=True \
    --gender=$gender \
    --model_folder /content/smplx/models_smplx_v1_1/models \
    --vposer_ckpt /content/vposer/V02_05\
    --part_segm_fn smplx_parts_segm.pkl

Dependency (important)

1. Install SMPL-X Body Model.
2. Install VPoser V2.0.
3. Install OpenPose

# Donwload Openpose
## There is code in colab. (Don't worry!!)

Quick Start🚶

Colab Code:

You may use V100 or A100 GPU.

GuideLine

0. If you get a warning about restarting the kernel, ignore it and click Cancel.

1. Input your images in /content/data/images folder.

2. Implement OpenPose and get keypoints.

# In colab, there is code.
## Automatic download packages and keypoints save. (Don't worry!!)

%cd /content
KEYPOINTS_DIR = os.path.join(RES_DIR, 'keypoints')
OPENPOSE_IMAGES_DIR = os.path.join(RES_DIR, 'openpose_images')
!mkdir $KEYPOINTS_DIR
!mkdir $OPENPOSE_IMAGES_DIR

!cd openpose && ./build/examples/openpose/openpose.bin --image_dir /content/data/images --write_json $KEYPOINTS_DIR --face --hand --display 0 --write_images $OPENPOSE_IMAGES_DIR

input_img_path = os.path.join(FRAMES_DIR, sorted(os.listdir(FRAMES_DIR))[0])
openpose_img_path = os.path.join(OPENPOSE_IMAGES_DIR, sorted(os.listdir(OPENPOSE_IMAGES_DIR))[0])

test_img = load_img(input_img_path)
open_pose_img = load_img(openpose_img_path)

plt.figure(figsize=(10, 10))
plt.title("Input Frame + Openpose Prediction")
plt.imshow(np.concatenate([test_img, open_pose_img], 1))

3. Prepare VPoser and SMPL-X models in your Google Drive.

!mkdir /content/gdrive/MyDrive/smplify-x/
!mkdir /content/gdrive/MyDrive/smplify-x/vposer
!mkdir /content/gdrive/MyDrive/smplify-x/smplx

You upload the zip files in each folder.

# In colab, it is required.
## SMPLX_ZIP_PATH and VPOSER_ZIP_PATH

%cd /content/
from google.colab import drive
drive.mount('/content/gdrive')

SMPLX_ZIP_PATH = '/content/gdrive/MyDrive/smplify-x/smplx/models_smplx_v1_1.zip' # @param {type:"string"}
VPOSER_ZIP_PATH = '/content/gdrive/MyDrive/smplify-x/vposer/V02_05.zip' # @param {type:"string"}

SMPLX_MODEL_PATH = '/content/smplx'
!mkdir $SMPLX_MODEL_PATH
!unzip -n $SMPLX_ZIP_PATH -d $SMPLX_MODEL_PATH
VPOSER_MODEL_PATH = '/content/vposer'
!mkdir $VPOSER_MODEL_PATH
!unzip -n $VPOSER_ZIP_PATH -d $VPOSER_MODEL_PATH

How to fix errors?

1. Install recent version VPoser and modifed code.

# In fit_single_frame.py (example)

## Original
from human_body_prior.tools.model_loader import load_vposer

## Modified (below)
from human_body_prior.tools.model_loader import load_model 
from human_body_prior.models.vposer_model import VPoser

2. Change VPoser implementation code

# In fitting.py (example)

## Original
body_pose = vposer.decode(pose_embedding, output_type='aa').view(1, -1) if use_vposer else None

## Modified
body_pose = (vposer.decode(pose_embedding).get( 'pose_body')).reshape(1, -1) if use_vposer else None

Option (3D visualization)

from vedo import Mesh

mesh = Mesh("./sample/000.obj",)
#mesh.texture("./sample/sample.jpg")

mesh.show()
