- # Preparing Inputs
-
- Tensorflow Object Detection API reads data using the TFRecord file format. Two
- sample scripts (`create_pascal_tf_record.py` and `create_pet_tf_record.py`) are
- provided to convert from the PASCAL VOC dataset and Oxford-IIIT Pet dataset to
- TFRecords.
-
- ## Generating the PASCAL VOC TFRecord files.
-
- The raw 2012 PASCAL VOC data set is located
- [here](http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar).
- To download, extract and convert it to TFRecords, run the following commands
- below:
-
- ```bash
- # From tensorflow/models/research/
- wget http://host.robots.ox.ac.uk/pascal/VOC/voc2012/VOCtrainval_11-May-2012.tar
- tar -xvf VOCtrainval_11-May-2012.tar
- python object_detection/dataset_tools/create_pascal_tf_record.py \
- --label_map_path=object_detection/data/pascal_label_map.pbtxt \
- --data_dir=VOCdevkit --year=VOC2012 --set=train \
- --output_path=pascal_train.record
- python object_detection/dataset_tools/create_pascal_tf_record.py \
- --label_map_path=object_detection/data/pascal_label_map.pbtxt \
- --data_dir=VOCdevkit --year=VOC2012 --set=val \
- --output_path=pascal_val.record
- ```
-
- You should end up with two TFRecord files named `pascal_train.record` and
- `pascal_val.record` in the `tensorflow/models/research/` directory.
-
- The label map for the PASCAL VOC data set can be found at
- `object_detection/data/pascal_label_map.pbtxt`.
-
- ## Generating the Oxford-IIIT Pet TFRecord files.
-
- The Oxford-IIIT Pet data set is located
- [here](http://www.robots.ox.ac.uk/~vgg/data/pets/). To download, extract and
- convert it to TFRecrods, run the following commands below:
-
- ```bash
- # From tensorflow/models/research/
- wget http://www.robots.ox.ac.uk/~vgg/data/pets/data/images.tar.gz
- wget http://www.robots.ox.ac.uk/~vgg/data/pets/data/annotations.tar.gz
- tar -xvf annotations.tar.gz
- tar -xvf images.tar.gz
- python object_detection/dataset_tools/create_pet_tf_record.py \
- --label_map_path=object_detection/data/pet_label_map.pbtxt \
- --data_dir=`pwd` \
- --output_dir=`pwd`
- ```
-
- You should end up with two 10-sharded TFRecord files named
- `pet_faces_train.record-?????-of-00010` and
- `pet_faces_val.record-?????-of-00010` in the `tensorflow/models/research/`
- directory.
-
- The label map for the Pet dataset can be found at
- `object_detection/data/pet_label_map.pbtxt`.
