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

目录组织与标注格式以源站说明和下载后实际文件为准。

数据说明

This folder contains the input files required for the R code used to analyse data for the Patterns and prevalence of food allergy in adulthood in the UK (PAFA) project. This includes:

• pafa_data_dictionary_anonymised.csv: The data dictionary describing each column in the anonymised PAFA dataset. “snomed_field_name” lists all column names in the dataset; “field_name_extended” lists the original column name in the REDCap data download, which was then recoded to include SNOMED and FoodEx2 codes for future analyses; “variable_field_name” denotes the corresponding coded field name in the REDCap form; “field_type” denotes the type of REDCap field; “field_label” describes the field name in plain language; “choices_calculations_or_slider_labels” describes the choices provided to the participant for that question.
• foodex2_codes_with_other.csv: A CSV file with key-value pairs for identifying foods coded in the dataset.
