2. Download the CIFAR-10 dataset.
```shell
$ curl -o cifar-10-python.tar.gz https://www.cs.toronto.edu/~kriz/cifar-10-python.tar.gz
$ tar xzf cifar-10-python.tar.gz
curl -o cifar-10-python.tar.gz https://www.cs.toronto.edu/~kriz/cifar-10-python.tar.gz
tar xzf cifar-10-python.tar.gz
```
After running the commands above, you should see the following files in the folder where the data was downloaded.
``` shell
$ ls -R cifar-10-batches-py
ls -R cifar-10-batches-py
```
The output should be:
```
batches.meta data_batch_1 data_batch_2 data_batch_3
data_batch_4 data_batch_5 readme.html test_batch
```
3. Generate TFRecord files.
This will generate a tf record for the training and test data available at the input_dir.
You can see more details in `generate_cifar10_tf_records.py`
```shell
# This will generate a tf record for the training and test data available at the input_dir.
# You can see more details in generate_cifar10_tf_records.py
$ python generate_cifar10_tfrecords.py --input-dir=/prefix/to/downloaded/data/cifar-10-batches-py \

python generate_cifar10_tfrecords.py --input-dir=${PWD}/cifar-10-batches-py \
--output-dir=${PWD}/cifar-10-batches-py
```
After running the command above, you should see the following new files in the output_dir.
``` shell
$ ls -R cifar-10-batches-py
ls -R cifar-10-batches-py
```
```
train.tfrecords validation.tfrecords eval.tfrecords
