在GitHub上下载了一个yolov8的代码,训练好检测模型,运行作者给的推理代码报错:
Traceback (most recent call last):

ModuleNotFoundError: No module named 'ultralytics.nn.modules.conv'; 'ultralytics.nn.modules' is not a package
作者仓库地址为:https://github.com/DataXujing/YOLOv8
首先看错误原因:'ultralytics.nn.modules'
is not a package,说明ultralytics.nn
模块有问题。
查看作者ultralytics
包的内容,并与最新版本对比:
8.0.0:
8.0.229:
可以看出,两者的modules
不同
解决办法很简单,把下载下来的nn
模块替换掉即可,问题解决。
