detect后图片输出无结果

在执行detect.py后，图片没有lable

wudashuo commented 3 years ago

如果系统是Windows的话，已经确定是有问题的，可以尝试降级pytorch至1.6版本，一般来说能解决问题。
如果是Linux或者MacOS的话，先试一下检测摄像头或者流媒体有没有问题，--source 0 或者--source rtsp://xxxxxxxxx，如果流媒体或者摄像头没问题，但是检测本地图片和视频检测不到，那么在这个else语句下添加cudnn.benchmark = True。这个不是正确的解决方案，只能让你检测到东西，检测结果会损失严重。
最好检查一下依赖是否符合requirements.txt里的要求，直接pip3 install -r requirements.txt，环境配对了一般没问题的。

能否贴下else语句我无法打开连接另外，我已经检查了我系统环境，没有问题

在detect.py 51行附近，原来的：

else:
    save_img = True
    dataset = LoadImages(source, img_size=imgsz, stride=stride)

改为：

else:
    cudnn.benchmark = True
    save_img = True
    dataset = LoadImages(source, img_size=imgsz, stride=stride)

改完检测应该会有结果，但是这个结果会很糟糕，我也没找到终极解决办法

好我已经修改完成结果确实稍微差点
