在服务器上运行train.py 一直无法解决这个问题 是cv的版本不对吗 可以告知下详细的环境配置吗

这个是因为你读取的数据的路径里有中文导致的吧，imread不能读取带有中文的路径

您好，请问您这个问题解决了吗？我也遇到了相同的问题，请指教。

您好，我找到了问题的原因是因为数据集的文件没有完全解压，不知道你的是不是。因为当时数据集在服务器上解压，粗心没有仔细看大小，只解压了一部分。所以您可以尝试完全解压数据集后再试试。

好的好的。谢谢您。我试试看

请问你解决了吗？怎么解决的 我也遇到了一样的问题。 此外，我对对应none的图片拿出来了，图片是OK的，路径也是OK的，就是图片读为none。。。。。。
