give the right path in terminal to import tfrecord file

I am following the guide of deeplab to train the provided model on the dataset cityscapes.

With the provided bash file (as the Step.1 in the guide), I converted the raw data to the form of tfrecord.

While in the Step.2 of the guide, I am requested to give the path to the dataset as a terminal flag "dataset_dir":

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

The guide's hint for the path is "${PATH_TO_DATASET} is the directory in which the Cityscapes dataset resides."

However,

the path to the upper folder of tfrecord
- (/home/workspace/models-master/research/deeplab/datasets/cityscapes/tfrecord/)
the path to a single tfrecord
- (/home/workspace/models-master/research/deeplab/datasets/cityscapes/tfrecord/train-00000-of-00010.tfrecord)

returned the following error, saying that such file can't be found:

    compat.as_bytes(pattern))

How to give the right path in order to import the tfrecord file? Am I right about the path, or the error may be somewhere else?

Solution

It turns out to be missing my user name in that address of home:

/home/USERNAME/workspace

instead of

/home/workspace
