# This script performs the following operations:
# 1. Downloads the Flowers dataset
# 2. Fine-tunes an Inception Resnet V2 model on the Flowers training set.
# 3. Evaluates the model on the Flowers validation set.
#
# Usage:
# cd slim
# ./slim/scripts/finetune_inception_resnet_v2_on_flowers.sh
set -e
# Where the pre-trained Inception Resnet V2 checkpoint is saved to.
PRETRAINED_CHECKPOINT_DIR=/tmp/checkpoints
# Where the pre-trained Inception Resnet V2 checkpoint is saved to.
MODEL_NAME=inception_resnet_v2
# Where the training (fine-tuned) checkpoint and logs will be saved to.
TRAIN_DIR=/tmp/flowers-models/${MODEL_NAME}
# Where the dataset is saved to.
DATASET_DIR=/tmp/flowers
# Download the pre-trained checkpoint.
