数据说明

Conditions: Adult Acute Myeloid Leukemia in Remission, Childhood Acute Lymphoblastic Leukemia in Remission, Childhood Acute Myeloid Leukemia in Remission, Childhood Myelodysplastic Syndrome, Childhood Renal Cell Carcinoma, Chronic Myelomonocytic Leukemia, Clear Cell Renal Cell Carcinoma, de Novo Myelodysplastic Syndrome. PRIMARY OBJECTIVES: I. To determine whether stable unrelated peripheral blood stem cell (PBSC) grafts can be safely established using nonmyeloablative pretransplant conditioning with intensified post-grafting immunosuppression and with every (q) 8 hours (hr) and possibly q 6 hr mycophenolate mofetil (MMF) dosing in patients with hematologic malignancies and renal cell carcinoma. II. To determine if the incidence and severity of acute grades II-IV graft-versus-host disease (GVHD) can be reduced in patients with sustained engraftment with the use of q 8 hr MMF dosing. SECONDARY OBJECTIVES: I. To determine if engraftment can be maintained in patients with low chimerism and high risk of rejection with the use of a single dose of fludarabine (fludarabine phosphate) followed by donor lymphocyte infusion (DLI) on continued MMF/cyclosporine (CSP). II. To compare survival and disease free survival to those achieved under protocol 1463. OUTLINE: REDUCED-INTENSITY CONDITIONING: Patients receive fludarabine phosphate intravenously (IV) on days -4, -3, and -2 and undergo total-body irradiation (TBI) on day 0. TRANSPLANT: Patients undergo allogeneic peripheral blood stem cell transplant (PBSCT) on day 0. IMMUNOSUPPRESSION: Patients receive cyclosporine orally (PO) twice daily (BID) on days -3 to 100 with taper to day 177 and mycophenolate mofetil PO every 8 hours on days 0-40 with taper to day 96. After completion of study treatment, patients are followed up at 6 months, 1 year, 1.5 years, 2 years, and then annually thereafter.

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
