python运行main.py报错

python3运行项目的main.py是报错提示系统找不到指定的路径

2个回答

你得把错误和代码贴出来啊,兄弟。难道我只告诉你我的程序异常退出,,你就能告诉我为什么?

那你就修改你的路径呗,或者确定你导入的路径是存在的,或者你在安装python的时候环境变量的功能没选上。这个要看具体的代码情况

在学习python flask migrate中,当在CMD中输入 python manager.py db migrate的时候,显示ImportError:DLL load failed,这个怎么解决?

在学习python flask的时候,我想进行数据迁移。 但当我初始化后, 继续在cmd里输入python manager.py db migrate的时候,系统提示说 **ImportError: DLL load failed: The specified module could not be found.** 不知道是哪里出了问题,小白一枚,求大神们帮帮忙。 下面的是我manager.py 的代码: ``` from flask_script import Manager from flaks_migrate import app from flask_migrate import Migrate,MigrateCommand from extension import db from models import Article manager = Manager(app) migrate = Migrate(app,db) manager.add_command('db',MigrateCommand) if __name__ == '__main__': manager.run() ```

YOLOv3是一种基于深度学习的端到端实时目标检测方法,以速度快见长。本课程将手把手地教大家使用labelImg标注和使用YOLOv3训练自己的数据集。课程分为三个小项目:足球目标检测(单目标检测)、梅西目标检测(单目标检测)、足球和梅西同时目标检测(两目标检测)。 本课程的YOLOv3使用Darknet,在Ubuntu系统上做项目演示。包括:安装Darknet、给自己的数据集打标签、整理自己的数据集、修改配置文件、训练自己的数据集、测试训练出的网络模型、性能统计(mAP计算和画出PR曲线)和先验框聚类。 Darknet是使用C语言实现的轻型开源深度学习框架,依赖少,可移植性好,值得深入探究。 除本课程《YOLOv3目标检测实战:训练自己的数据集》外,本人推出了有关YOLOv3目标检测的系列课程,请持续关注该系列的其它课程视频,包括: 《YOLOv3目标检测实战:交通标志识别》 《YOLOv3目标检测:原理与源码解析》 《YOLOv3目标检测:网络模型改进方法》 敬请关注并选择学习!

技术大佬:我去,你写的 switch 语句也太老土了吧

昨天早上通过远程的方式 review 了两名新来同事的代码,大部分代码都写得很漂亮,严谨的同时注释也很到位,这令我非常满意。但当我看到他们当中有一个人写的 switch 语句时,还是忍不住破口大骂:“我擦,小王,你丫写的 switch 语句也太老土了吧!” 来看看小王写的代码吧,看完不要骂我装逼啊。 private static String createPlayer(PlayerTypes p...
