        ## About the Project
        
        Many deep learning toolkits are available on GitHub; however, we couldn't find one that would suit our needs.
        So, we created this improved one. This toolkit minimizes the deep learning teams' coding efforts to utilize the
        functionalities of famous deep learning models such as MTCNN in face detection, yolov5 in object detection, and many
        other repositories and models in various fields. In addition, it provides functionalities for preprocessing, monitoring,
        and manipulating datasets that can come in handy in any programming project.
        
        **What we have done so far:**
        
        * The outputs of all the models are standard numpy
        * Single predict and batch predict of all models are ready
        * handy functions and tools are tested and ready to use

        # Vision
        
        We support two subsets of models in Computer Vision.
        
        * Face Detection
        * Object Detection
        
        ## Face Detection
        
        We have gathered a rich collection of face detection models which are mentioned in the following list. If you notice any
        model missing, feel free to open an issue or create a pull request.
        
        ### MTCNN
        
        [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/pooya-mohammadi/Face/blob/master/_02_mtcnn_tf1/deep_utils_mtcnn.ipynb)
        
        1. After Installing the library, import deep_utils and instantiate the model:
        
        ```python
        from deep_utils import face_detector_loader, list_face_detection_models
        
        # This line will print all the available models
        print(list_face_detection_models())
        
        # Create a face detection model using MTCNN-Torch
        face_detector = face_detector_loader('MTCNNTorchFaceDetector')
        ```
        
        2. The model is instantiated, Now let's Detect an image:
        
        ```python
        import cv2
        from deep_utils import show_destroy_cv2, Box, download_file, Point
        
        # Download an image
        download_file(
            "https://raw.githubusercontent.com/pooya-mohammadi/deep_utils/master/examples/vision/data/movie-stars.jpg")
        
        # Load an image
        img = cv2.imread("movie-stars.jpg")
        
        # show the image. Press a button to proceed
        show_destroy_cv2(img)
        
        # Detect the faces
        result = face_detector.detect_faces(img, is_rgb=False)
        
        # Draw detected boxes on the image.
        img = Box.put_box(img, result.boxes)
        
        # Draw the landmarks
        for landmarks in result.landmarks:
            Point.put_point(img, list(landmarks.logs()), radius=3)
        
        # show the results
        show_destroy_cv2(img)
        ```
        
        The result:
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep_utils/master/examples/vision/data/movie-starts-mtccn-torch.jpg" alt="Logo" >
        <p align="right">(<a href="#top">back to top</a>)</p>
        
        ## Object Detection
        
        ### YoloV5
        
        YoloV5 by far is one of the top-5 most used object detection models. The training process is straight forward and the
        results
        are spectacular. However, using a trained model can be very challenging because of several files that yolov5's model
        needs in production.
        To tackle this issue we have wrapped yolov5's models in a simple module whose usage will be illustrated in the following
        section.<br/>
        
        [![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/pooya-mohammadi/deep-utils-notebooks/blob/main/vision/object-detection/yolov5/deep-utils-yolov5.ipynb)
        
        1. After Installing the library, import deep_utils and instantiate the model:
        
        ```python
        # import the model
        from deep_utils import YOLOV5TorchObjectDetector
        
        # instantiate with the default parameters
        yolov5 = YOLOV5TorchObjectDetector()
        # print the parameters
        print(yolov5)
        ```
        
        2. Download and visualize the test image
        
        ```python
        import cv2
        from deep_utils import Box, download_file, Point, show_destroy_cv2
        from PIL import Image
        
        # Download an image
        download_file("https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/vision/images/dog.jpg")
        
        # Load an image
        base_image = cv2.imread("dog.jpg")
        
        # pil.Image is used for visualization
        Image.fromarray(base_image[..., ::-1])  # convert to rgb
        # visualize using oepncv
        # show_destroy_cv2(base_image)
        ```
        
        The result:
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/vision/images/dog.jpg" alt="Logo" >
        <p align="right">(<a href="#top">back to top</a>)</p>
        
        3. Detect and visualize Objects
        
        ```python
        # Detect the objects
        # the image is opened by cv2 which results to a BGR image. Therefore the `is_rgb` is set to `False`
        result = yolov5.detect_objects(base_image, is_rgb=False, confidence=0.5)
        
        # Draw detected boxes on the image.
        img = Box.put_box_text(base_image,
                               box=result.boxes,
                               label=[f"{c_n} {c}" for c_n, c in zip(result.class_names, result.confidences)])
        
        # pil.Image is used for visualization
        Image.fromarray(img[..., ::-1])  # convert to rgb
        # visualize using oepncv
        # show_destroy_cv2(img)
        ```
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/vision/images/dog_yolov5.jpg" alt="Logo" >
        <p align="right">(<a href="#top">back to top</a>)</p>
        
        ## NLP
        
        In this section, models and utilities for nlp projects are provided
        
        ### NER
        
        Name Entity Recognition
        
        #### multi-label-stratify
        
        ## Augmentation
        
        ### CutMix
        
        <a href="https://colab.research.google.com/github/pooya-mohammadi/deep-utils-notebooks/blob/main/augmentation/cutmix/cutmix_tf.ipynb" target="_parent"><img src="https://colab.research.google.com/assets/colab-badge.svg" alt="Open In Colab"/></a>
        
        CutMix is one of the best augmentation methods that's proven to be very effective in different vision-based project.
        Therefore, CutMix is now available on `deep_utils` to be used both for segmentation and classification tasks. Let some
        examples:
        
        #### Segmentation
        
        ```python
        import cv2
        import numpy as np
        from PIL import Image
        from deep_utils import CutMixTF, group_show, repeat_dimension
        
        # creating random images, the code for this section can be found in the colab notebook
        image_a = np.zeros((300, 300, 3), np.uint8) * 255
        mask_a = np.zeros_like(image_a)
        pt1 = (150, 100)
        pt2 = (100, 200)
        pt3 = (200, 200)
        
        triangle_cnt = np.array([pt1, pt2, pt3])
        
        image_a = cv2.drawContours(image_a, [triangle_cnt], 0, (0, 255, 0), -1)
        mask_a = cv2.drawContours(mask_a, [triangle_cnt], 0, (255, 255, 255), -1)
        
        image_b = np.zeros((300, 300, 3), np.uint8) * 255
        mask_b = np.zeros_like(image_b)
        
        pt1 = (150, 150)
        
        image_b = cv2.circle(image_b, pt1, 50, (0, 255, 0), -1)
        mask_b = cv2.circle(mask_b, pt1, 50, (255, 255, 255), -1)
        
        # CutMix for two individual images:
        cutmix_img, cutmix_mask = CutMixTF.seg_cutmix(image_a, mask_a[..., 0], image_b, mask_b[..., 0], beta=1)
        ```
        
        The input and output are as follows:
        
        **Input:**
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/augmentation/cutmix/two_images.jpg" alt="Logo" ><br/>
        
        **Output:**
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/augmentation/cutmix/cutmix_two_images.jpg" alt="Logo" >
        
        As it illustrated in the above image a section of the triangle and the circle are combined together. By
        changing `seg_cutmix` to `seg_cutmix_batch` one can use CutMix augmentation for batch of images.
        
        ```python
        cutmix_img, cutmix_mask = CutMixTF.seg_cutmix_batch(a_images=batch_img, a_masks=batch_mask[..., 0], beta=1)
        ```
        
        **Input:**
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/augmentation/cutmix/batch_img.jpg" alt="cutmix" ><br/>
        
        **Output:**
        
        <img src="https://raw.githubusercontent.com/pooya-mohammadi/deep-utils-notebooks/main/augmentation/cutmix/batch_cutmix.jpg" alt="cutmix" >

        ## Utils
        
        In this section, various utility functions are provided.
        
        ### DictNamedTuple
        
        In this custom data type, we have added the methods of the Dict type to the NamedTuple type. You have access to .get(),
        .values(), .items() alongside all of the functionalities of a NamedTuple. Also, all the outputs of our models are
        DictNamedTuple, and you can modify and manipulate them easily. Let's see how to use it:
        
        ```
        from deep_utils import dictnamedtuple
        # create a new object
        dict_object = dictnamedtuple(typename='letters', field_names=['firstname', 'lastname'])
        # pass the values
        instance_dict = dict_object(firstname='pooya', lastname='mohammadi')
        
        # get items and ...
        print("items: ", instance_dict.items())
        print("keys: ", instance_dict.keys())
        print("values: ", instance_dict.values())
        print("firstname: ", instance_dict.firstname)
        print("firstname: ", instance_dict['firstname'])
        print("lastname: ", instance_dict.lastname)
        print("lastname: ", instance_dict['lastname'])
        ```
        
        ```
        # results
        items:  [('firstname', 'pooya'), ('lastname', 'mohammadi')]
        keys:  ['firstname', 'lastname']
        values:  ['pooya', 'mohammadi']
        firstname:  pooya
        firstname:  pooya
        lastname:  mohammadi
        lastname:  mohammadi
        ```
        
        <p align="right">(<a href="#top">back to top</a>)</p>
        
        ### Multi-Label-Stratify
        
        While splitting a dataset for NER or Object detection tasks, you might have noticed that there is no way to split the
        dataset using
        stratify functionality of `train_test_split` of the `scikit-learn` library because not only does each sample in these two tasks may
        have
        more than one tag/object, but also each tag/object of each class may appear more than once. For example, an image/sample may
        contain two dogs and three cats, which means the label/y of that sample would be like [2, 3] in which the index zero
        corresponds
        to the dog class, and the index one corresponds to the cat class.
        To split these types of datasets, the following function is
        developed in the `deep_utils` library which is very easy to use. To use this function, two arrays are needed. The first
        is an array
        or list containing the input samples. The type of these samples could be anything; they could be a list of sentences, a
        list of
        paths to input images, or even structured data like the one in the following example. The other array, however, must be
        a 2D ndarray whose first dimension is equal to the number of samples, and the second dimension is equal to the number
        of the classes. Likewise, each index is correspondent to a class, and each element of this array shows the number of
        each sample in a specific class. For example, the element in index `[0, 0]` of the following array
        `[[1, 0], [3, 3]]`, which is equal to 1, shows that the sample 0 contains 1 item of the first class or the class that
        corresponds to index zero. Now, let's see an example:
        
        ```commandline
        >>> from deep_utils import stratify_train_test_split_multi_label
        >>> x = np.array([[1, 2], [3, 4], [1, 2], [3, 4], [1, 2], [3, 4], [1, 2], [3, 4]])
        >>> y = np.array([[0, 0], [0, 0], [0, 1], [0, 1], [1, 1], [1, 1], [1, 0], [1, 0]])
        >>> x_train, x_test, y_train, y_test = stratify_train_test_split_multi_label(x, y, test_size=0.5, closest_ratio=False)
        >>> x_train
            array([[1, 2],
                   [3, 4],
                   [1, 2],
                   [3, 4]])
        >>> x_test
        array([[1, 2],
               [3, 4],
               [1, 2],
               [3, 4]])
        >>> y_train
        array([[0, 1],
               [0, 1],
               [1, 0],
               [1, 0]])
        >>> y_test
        array([[1, 1],
               [1, 1],
               [0, 0],
               [0, 0]])
        >>> print("class ratio:", tuple(y_test.sum(0) / y.sum(0)))
        class ratio: (0.5, 0.5)
        >>> print("sample ratio:", y_test.shape[0] / y.shape[0])
        sample ratio: 0.5
        ```
        
        As clearly shown in the results, both the sample and the class ratios are preserved. In some datasets,
        it's impossible to get the exact expected ratio, so the function will split the input dataset in a way that it would

        ## Tests
        
        Tests are done for python 3.8 and 3.9. Deep-Utils will probably run without any errors on lower versions as well.
        
        **Note**: Model tests are done on CPU devices provided by GitHub Actions. GPU based models are tested manually by the
        authors.
