将数据集的VOC格式转为yolo格式

pyqt中关于QMediaPlayer无法打开播放视频的问题

深度学习中Linux常用命令，持续更新ing

批量读取文件夹中的图片，并把图片名写入txt文档中

No dashboards are active for the current data set.Probable causes:You haven’t written any data to your event files.TensorBoard can’t find your event files.解决：1）原来文件夹以test开头，后来删掉了2）中文路径可以运行但打不开，故修改为英文路径tensorboard --logdir=./runs和tensorboard --logdir

自定义一个增加椒盐噪声的transforms方法:import randomfrom PIL import Imageimport numpy as npclass AddPepperNoise(object): """" Args: snr (float): Signal Noise Rate p (float): 概率值， 依概率执行 """ def __init__(self, snr, p=0.9): as

自定义的数据集：从kaggle下载的猫狗数据集import osfrom PIL import Imagefrom torch.utils.data import Datasetcatdog_label = {"cats": 0, "dogs": 1}class DogCatDataset(Dataset): def __init__(self, data_dir, transform=None): """" 猫狗分类任务的dataset

自定义的dataset,但’DogCatDataset’ is not callablefrom torchvision import transformsimport DogCatDatasetimport osfrom torch.utils.data import DataLoader# 文件夹路径split_dir = 'DogCatDataset'train_dir = os.path.join(split_dir, "training_set")valid_dir = os

问题：AttributeError: ‘str’ object has no attribute ‘endwith’catdog_label = {"cats": 0, "dogs": 1}data_info = list()for root, dirs, _ in os.walk(data_dir): # 遍历类别 for sub_dir in dirs: img_names = os.listdir(os.path.join(root, sub_dir))

####把文件名从"tiff"格式转化为"jpg"格式import ospath = r'E:\study\NLP\2\jaffe'#读取此目录下的所有文件夹files = os.listdir(path)for file in files: newfile = file.replace('tiff','jpg') oldfile_path = os.path.join(path, file) newfile_path = os.path.join(path, new.
