## Train
1. Requirements:
+ Python >= 3.6
+ Tensorflow >= 2.2.0rc3
2. To train the network on your own dataset, you can put the dataset under the folder **original dataset**, and the directory should look like this:
```
|——original dataset
|——class_name_0
|——class_name_1
|——class_name_2
|——class_name_3
```
3. Run the script **split_dataset.py** to split the raw dataset into train set, valid set and test set. The dataset directory will be like this:
```
|——dataset
|——train
|——class_name_1
|——class_name_2
......
|——class_name_n
|——valid
|——class_name_1
|——class_name_2
......
|——class_name_n
|—-test
|——class_name_1
|——class_name_2
......
|——class_name_n
```
4. Run **to_tfrecord.py** to generate tfrecord files.
5. Change the corresponding parameters in **config.py**.
6. Run **train.py** to start training.
If you want to train the *EfficientNet*, you should change the IMAGE_HEIGHT and IMAGE_WIDTH to *resolution* in the params, and then run **train.py** to start training.
## Evaluate
Run **evaluate.py** to evaluate the model's performance on the test dataset.
