Question

我正在尝试设置Tensorflow的Object Detection API并关注this doc

我正在训练我的模型时遇到以下错误（它抱怨找不到检查点文件，但它存在）：

我尝试过Windows和Linux格式的检查点文件路径，我收到以下错误：

Windows格式路径（'C：\ ObjectDetectionaster_rcnn_resnet101_coco_11_06_2017 \ model.ckpt'）

           aster_rcnn_resnet101_coco_11_06_2017 : The filename, directory name, or volume label syntax is incorrect.

Linux格式路径（'/c/ObjectDetection/faster_rcnn_resnet101_coco_11_06_2017/model.ckpt'）

正如您的错误消息所说，这是路径的问题，而不是TensorFlow功能的问题。

即使在Git Bash中，我也使用标准的Windows样式路径，即'C：\'而不是'/ c /'。此外，您需要转义\或使其成为原始字符串。如：

'C:\\ObjectDetection\\faster_rcnn_resnet101_coco_11_06_2017\\model.ckpt'
# or
r'C:\ObjectDetection\\faster_rcnn_resnet101_coco_11_06_2017\\model.ckpt'

请注意，在您的粘贴路径中，它显示C:\ObjectDetectionaster_rcnn_...而不是C:\ObjectDetection\faster_rcnn_...。那是因为\f引用了转义序列：

>>> print('\f')


>>> ord('\f')
12
>>> print('\\f')  # escape the slash
\f
>>> print(r'\f')  # or use raw strings with the 'r' prefix
\f
