【问题描述】：

自从我使用 ssdlite_mobilenet_v2_coco 模型以来，我一直在 github 上关注本指南并进行了一些更改，但遇到了未知错误。

; Unknown error**

我通过 anaconda 在 tensorflow-gpu 1.8 上运行时尝试了 train.py 和 model_main.py。

在训练文件夹中 labelmap.pbtxt 确实存在我不知道为什么它试图找到“raining\labelmap.pbtxt”

【问题讨论】：

在这种情况下必须显示您所做的更改，因为这很可能是导致错误的原因。请编辑您的帖子以包含代码
你能给文件的完整路径而不是“raining\labelmap.pbtxt”

标签： python-3.x windows tensorflow gpu object-detection

【解决方案1】：

将您指定的文件路径中的反斜杠 (\) 替换为正斜杠 (/)。它对我有用。

【解决方案2】：

您应该尝试指定 labelmap.pbtxt 文件的绝对路径，否则您的当前目录路径不正确
