Methods
_______
predict(img_names_path=None, img_list=[], save_predictions=False, predictions_path='predictions.json', save_crops=False, crop_dir='./cropped_img')
loads img_names.txt from str 'img_names_path', imports images
img_names.txt contains absolute paths of images, separated by line break
or, just input images as a list
predicts on list of images using self.model
saves output to predictions_path if save_predictions = True
saves cropped images to crop_dir if save_crops = True
