谷歌协作：[Errno 2]没有这样的文件或目录：'Tensorflow/workspace/annotations\\label_map.pbtxt‘

Question

我正在尝试使用tensorflow做一个物体检测项目，这让我停了三天。

WORKSPACE_PATH = 'Tensorflow/workspace'
SCRIPTS_PATH = 'Tensorflow/scripts'
APIMODEL_PATH = 'Tensorflow/models'
ANNOTATION_PATH = WORKSPACE_PATH+'/annotations'
IMAGE_PATH = WORKSPACE_PATH+'/images'
MODEL_PATH = WORKSPACE_PATH+'/models'
PRETRAINED_MODEL_PATH = WORKSPACE_PATH+'/pre-trained-models'
CONFIG_PATH = MODEL_PATH+'/my_ssd_mobnet/pipeline.config'
CHECKPOINT_PATH = MODEL_PATH+'/my_ssd_mobnet/'

这是编译好的。

labels = [{'name':'A', 'id':1}, 
          {'name':'B', 'id':2},
          {'name':'C', 'id':3},
          {'name':'D', 'id':4},
          {'name':'E', 'id':5},
          {'name':'F', 'id':6},
          {'name':'G', 'id':7},
          {'name':'H', 'id':8},
          {'name':'I', 'id':9},
          {'name':'K', 'id':10},
          {'name':'L', 'id':11},
          {'name':'M', 'id':12},
          {'name':'N', 'id':13},
          {'name':'O', 'id':14},
          {'name':'P', 'id':15},

          {'name':'W', 'id':22},
          {'name':'X', 'id':23},
          {'name':'Y', 'id':24},
          ]

with open(ANNOTATION_PATH + '\label_map.pbtxt', 'w') as f:
    for label in labels:
        f.write('item { \n')
        f.write('\tname:\'{}\'\n'.format(label['name']))
        f.write('\tid:{}\n'.format(label['id']))
        f.write('}\n')

FileNotFoundError                         Traceback (most recent call last)

FileNotFoundError: [Errno 2] No such file or directory: 'Tensorflow/workspace/annotations\\label_map.pbtxt'

如果有人能帮助我，我将不胜感激！

Answer 1

使用!pwd检查您当前的工作目录。

这可能是因为您在错误的文件夹中，或者在Tensorflow文件夹中，您无法从该文件夹访问ANNOTATION_PATH。

如果你在Tensorflow文件夹中，使用%cd ../ (返回一个文件夹)并将\label_map.pbtxt更改为/label_map.pbtxt。

Answer 2

您必须提供完整路径，例如，如果该路径位于D文件夹中，则路径应为WORKSPACE_PATH = 'D:/Tensorflow/workspace‘
