4. 迁移学习代码显示ValueError: Expected model output height to be 1!
  • 免费好用的星瞳AI云服务上线！简单标注，云端训练，支持OpenMV H7和OpenMV H7 Plus。可以替代edge impulse。 https://forum.singtown.com/topic/9519
  • 我们只解决官方正版的OpenMV的问题（STM32），其他的分支有很多兼容问题，我们无法解决。
  • 如果有产品硬件故障问题，比如无法开机，论坛很难解决。可以直接找售后维修。
  • 发帖子之前，请确认看过所有的视频教程，https://singtown.com/learn/ 和所有的上手教程http://book.openmv.cc/
  • 每一个新的提问，单独发一个新帖子
  • 帖子需要目的，你要做什么？
  • 如果涉及代码，需要报错提示与全部代码文本，请注意不要贴代码图片
  • 必看：玩转星瞳论坛了解一下图片上传，代码格式等问题。

      使用edge impluse网站的迁移学习训练出来的代码显示错误怎么解决呀？
      很急，有没有大佬帮忙看看

      for obj in net.classify(img, min_scale=1.0, scale_mul=0.8, x_overlap=0.5, y_overlap=0.5):这行代码显示的错误

    • 看上去你的代码和模型不匹配，你要用edge impulse下载下来的代码。
