数据说明

Conditions: Liver Diseases, Fibrosis, Liver, Cirrhosis, Liver. Hypothesis: A technology-assisted self-management intervention that addresses diet, physical activity, alcohol use, and medication adherence can produce regression in fibrosis as measured by FIB-4 in patients with fibrosis or steatosis and risk factors for cirrhosis, including chronic hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, alcohol use, or non-alcoholic fatty liver disease (NAFLD). Primary objective: To test the effect of the behavioral intervention on fibrosis in a randomized trial. We will randomize eligible HOPE Clinic patients to (i) a 6-month self-management intervention to help participants implement behavioral changes to manage their disease or (ii) a wait-list control group that will receive the intervention after their 6-month assessment. Secondary objective: Evaluate changes in behavioral risk factors for liver fibrosis or steatosis (body composition, physical activity, diet, medication adherence, alcohol use), metabolic syndrome, and patient activation and other behavioral determinants.

数据加载示例（图像类）

from PIL import Image
import glob, os

files = (glob.glob(os.path.join(path, "**", "*.png"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.jpg"), recursive=True)
       + glob.glob(os.path.join(path, "**", "*.tif"), recursive=True))
print("图像文件数:", len(files))
img = Image.open(files[0]); print("尺寸/模式:", img.size, img.mode)

# torchvision Dataset 方式:
# from torchvision import datasets
# ds = datasets.ImageFolder(path)  # 要求 子目录=类别
