数据说明

Conditions: Acute Lymphoblastic Leukemia/Lymphoma, Myelodysplasia, Acute Myelogenous Leukemia, Juvenile Myelomonocytic Leukemia, Chronic Myelogenous Leukemia. This is a prospective non-therapeutic study, assessing the long-term toxicity of pediatric HCT for hematologic malignancies. This study is a collaboration between the Pediatric Blood and Marrow Transplant Consortium (PBMTC), the Center for International Blood and Marrow Transplant Research (CIBMTR), the National Marrow Transplant Program (NMDP) and the Resource for Clinical Investigation in Blood and Marrow Transplantation (RCI-BMT) of the CIBMTR. The study will enroll pediatric patients who undergo myeloablative HCT for hematologic malignancies at PBMTC sites. The study examines the hypothesis that survivors of pediatric HCT are at risk for late organ toxicity and they will have identifiable biomarkers present within the first two years following HCT which will be predictive for late adverse outcomes allowing for early identification of patients at risk.

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
