数据说明

Conditions: Myelodysplastic Syndrome, Leukemia, Myelomonocytic, Juvenile. Study Population Pediatric subjects aged 1 month to less than 18 years of age with newly diagnosed conditions of advanced myelodysplastic syndrome (MDS) or juvenile myelomonocytic leukemia (JMML). Length of Study The enrollment period will last for up to 22 months with subjects being treated for a minimum of 3 months and a maximum of 6 months, until transplantation or disease progression (based on an independent central review of responses). Once investigational product (IP) has been discontinued, subjects will then be followed for 1 year after the last dose of investigational product (IP). The follow-up may not be terminated because of new anticancer treatment or hematopoietic stem cell transplantation (HSCT). The End of Trial is defined as either the date of the last visit of the last subject to complete the study, or the date of receipt of the last data point from the last subject that is required for primary, secondary and/or exploratory analysis, as pre-specified in the protocol and/or the Statistical Analysis Plan (SAP), whichever is the later date.

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
