在终端中给出正确的路径以导入 tfrecord 文件

Question

我正在按照 deeplab 的指南在数据集 cityscapes 上训练提供的模型。

使用提供的bash文件（作为指南中的Step.1），我将原始数据转换为tfrecord的形式。

在指南的第 2 步中，我被要求提供数据集的路径作为终端标志 "dataset_dir":

python deeplab/train.py \ # ... some unrelevant flags
    --train_logdir=${PATH_TO_TRAIN_DIR} \
    --dataset_dir=${PATH_TO_DATASET}

指南的路径提示是“${PATH_TO_DATASET} 是 Cityscapes 数据集所在的目录。”

然而，

tfrecord 上层文件夹路径
- (/home/workspace/models-master/research/deeplab/datasets/cityscapes/tfrecord/)
单个 tfrecord 的路径
- (/home/workspace/models-master/research/deeplab/datasets/cityscapes/tfrecord/train-00000-of-00010.tfrecord)

返回以下错误，说找不到这样的文件：

如何给出正确的路径以导入tfrecord文件？我的路径是否正确，或者错误可能出在其他地方？

Answer 1

原来那个家地址里少了我的用户名：

/home/USERNAME/workspace

而不是

/home/workspace

在终端中给出正确的路径以导入 tfrecord 文件

give the right path in terminal to import tfrecord file

python

tensorflow

tfrecord
