You can control the number of image predictions that Comet ML logs during your experiments. By default, Comet ML logs 100 image predictions from the validation set. However, you can change this number to better suit your requirements. For example, to log 200 image predictions, use the following code:

import os

os.environ["COMET_MAX_IMAGE_PREDICTIONS"] = "200"

Batch Logging Interval

Comet ML allows you to specify how often batches of image predictions are logged. The COMET_EVAL_BATCH_LOGGING_INTERVAL environment variable controls this frequency. The default setting is 1, which logs predictions from every validation batch. You can adjust this value to log predictions at a different interval. For instance, setting it to 4 will log predictions from every fourth batch.

import os

os.environ["COMET_EVAL_BATCH_LOGGING_INTERVAL"] = "4"

Disabling Confusion Matrix Logging

In some cases, you may not want to log the confusion matrix from your validation set after every epoch. You can disable this feature by setting the COMET_EVAL_LOG_CONFUSION_MATRIX environment variable to "false." The confusion matrix will only be logged once, after the training is completed.

import os

os.environ["COMET_EVAL_LOG_CONFUSION_MATRIX"] = "false"

Offline Logging

If you find yourself in a situation where internet access is limited, Comet ML provides an offline logging option. You can set the COMET_MODE environment variable to "offline" to enable this feature. Your experiment data will be saved locally in a directory that you can later upload to Comet ML when internet connectivity is available.

    # Store working directory path as work_dir
    work_dir = os.getcwd()

    # Print work_dir path
    print(os.getcwd())

    # Print work_dir contents
    print(os.listdir(f"{work_dir}"))

    # Print trash_ICRA19 subdirectory contents
    print(os.listdir(f"{work_dir}/trash_ICRA19"))
    ```

After loading the dataset, we printed and saved our working directory. We have also printed the contents of our working directory to confirm the "trash_ICRA19" data set was loaded properly.

If you see "trash_ICRA19" among the directory's contents, then it has loaded successfully. You should see three files/folders: a config.yaml file, a videos_for_testing directory, and a dataset directory. We will ignore the videos_for_testing directory, so feel free to delete it.

We will use the config.yaml file and the contents of the dataset directory to train our object detection model. Here is a sample image from our marine litter data set.

Step 4: Preprocess the Data

Fortunately, all labels in the marine litter data set are already formatted as YOLO .txt files. However, we need to rearrange the structure of the image and label directories in order to help our model process the image and labels. Right now, our loaded data set directory follows this structure:

But, YOLO models by default require separate images and labels in subdirectories within the train/val/test split. We need to reorganize the directory into the following structure:

To reorganize the data set directory, we can run the following script:

!!! Example "Preprocess the Data"

=== "Python"

    ```py
    # Function to reorganize dir
    def organize_files(directory):
        for subdir in ["train", "test", "val"]:
            subdir_path = os.path.join(directory, subdir)
            if not os.path.exists(subdir_path):
                continue

            images_dir = os.path.join(subdir_path, "images")
            labels_dir = os.path.join(subdir_path, "labels")

            # Create image and label subdirs if non-existent
            os.makedirs(images_dir, exist_ok=True)
            os.makedirs(labels_dir, exist_ok=True)

            # Move images and labels to respective subdirs
            for filename in os.listdir(subdir_path):
                if filename.endswith(".txt"):
                    shutil.move(os.path.join(subdir_path, filename), os.path.join(labels_dir, filename))
                elif filename.endswith(".jpg") or filename.endswith(".png") or filename.endswith(".jpeg"):
                    shutil.move(os.path.join(subdir_path, filename), os.path.join(images_dir, filename))
                # Delete .xml files
                elif filename.endswith(".xml"):
                    os.remove(os.path.join(subdir_path, filename))


    if __name__ == "__main__":
        directory = f"{work_dir}/trash_ICRA19/dataset"
        organize_files(directory)
    ```

Next, we need to modify the .yaml file for the data set. This is the setup we will use in our .yaml file. Class ID numbers start from 0:

path: /path/to/dataset/directory # root directory for dataset
train: train/images # train images subdirectory
val: train/images # validation images subdirectory
test: test/images # test images subdirectory

# Classes
names:
    0: plastic
    1: bio
    2: rov

Run the following script to delete the current contents of config.yaml and replace it with the above contents that reflect our new data set directory structure. Be certain to replace the work_dir portion of the root directory path in line 4 with your own working directory path we retrieved earlier. Leave the train, val, and test subdirectory definitions. Also, do not change {work_dir} in line 23 of the code.

!!! Example "Edit the .yaml File"

=== "Python"

    ```py
    # Contents of new confg.yaml file
    def update_yaml_file(file_path):
        data = {
            "path": "work_dir/trash_ICRA19/dataset",
            "train": "train/images",
            "val": "train/images",
            "test": "test/images",
            "names": {0: "plastic", 1: "bio", 2: "rov"},
        }

        # Ensures the "names" list appears after the sub/directories
        names_data = data.pop("names")
        with open(file_path, "w") as yaml_file:
            yaml.dump(data, yaml_file)
            yaml_file.write("\n")
            yaml.dump({"names": names_data}, yaml_file)


    if __name__ == "__main__":
        file_path = f"{work_dir}/trash_ICRA19/config.yaml"  # .yaml file path
        update_yaml_file(file_path)
        print(f"{file_path} updated successfully.")
    ```

Step 5: Train the YOLOv8 model

Run the following command-line code to fine tune a pretrained default YOLOv8 model.

!!! Example "Train the YOLOv8 model"

=== "CLI"

    ```py
    !yolo task=detect mode=train data={work_dir}/trash_ICRA19/config.yaml model=yolov8s.pt epochs=2 batch=32 lr0=.04 plots=True
    ```

Here's a closer look at the parameters in the model training command:

• task: It specifies the computer vision task for which you are using the specified YOLO model and data set.
• mode: Denotes the purpose for which you are loading the specified model and data. Since we are training a model, it is set to "train." Later, when we test our model's performance, we will set it to "predict."
• epochs: This delimits the number of times YOLOv8 will pass through our entire data set.
• batch: The numerical value stipulates the training batch sizes. Batches are the number of images a model processes before it updates its parameters.
• lr0: Specifies the model's initial learning rate.
• plots: Directs YOLO to generate and save plots of our model's training and evaluation metrics.

For a detailed understanding of the model training process and best practices, refer to the YOLOv8 Model Training guide. This guide will help you get the most out of your experiments and ensure you're using YOLOv8 effectively.

Step 6: Test the Model

We can now run inference to test the performance of our fine-tuned model:

!!! Example "Test the YOLOv8 model"

=== "CLI"

    ```py
    !yolo task=detect mode=predict source={work_dir}/trash_ICRA19/dataset/test/images model={work_dir}/runs/detect/train/weights/best.pt conf=0.5 iou=.5 save=True save_txt=True
    ```

This brief script generates predicted labels for each image in our test set, as well as new output image files that overlay the predicted bounding box atop the original image.

Predicted .txt labels for each image are saved via the save_txt=True argument and the output images with bounding box overlays are generated through the save=True argument.
The parameter conf=0.5 informs the model to ignore all predictions with a confidence level of less than 50%.

Lastly, iou=.5 directs the model to ignore boxes in the same class with an overlap of 50% or greater. It helps to reduce potential duplicate boxes generated for the same object.
we can load the images with predicted bounding box overlays to view how our model performs on a handful of images.

!!! Example "Display Predictions"

=== "Python"

    ```py
    # Show the first ten images from the preceding prediction task
    for pred_dir in glob.glob(f"{work_dir}/runs/detect/predict/*.jpg")[:10]:
        img = Image.open(pred_dir)
        display(img)
    ```

The code above displays ten images from the test set with their predicted bounding boxes, accompanied by class name labels and confidence levels.

Step 7: Evaluate the Model

We can produce visualizations of the model's precision and recall for each class. These visualizations are saved in the home directory, under the train folder. The precision score is displayed in the P_curve.png:

The graph shows an exponential increase in precision as the model's confidence level for predictions increases. However, the model precision has not yet leveled out at a certain confidence level after two epochs.

The recall graph (R_curve.png) displays an inverse trend:

Unlike precision, recall moves in the opposite direction, showing greater recall with lower confidence instances and lower recall with higher confidence instances. This is an apt example of the trade-off in precision and recall for classification models.

Step 8: Calculating Intersection Over Union

You can measure the prediction accuracy by calculating the IoU between a predicted bounding box and a ground truth bounding box for the same object. Check out IBM's tutorial on training YOLOv8 for more details.

A Guide on How to Use JupyterLab to Train Your YOLOv8 Models

Building deep learning models can be tough, especially when you don't have the right tools or environment to work with. If you are facing this issue, JupyterLab might be the right solution for you. JupyterLab is a user-friendly, web-based platform that makes coding more flexible and interactive. You can use it to handle big datasets, create complex models, and even collaborate with others, all in one place.

You can use JupyterLab to work on projects related to Ultralytics YOLOv8 models. JupyterLab is a great option for efficient model development and experimentation. It makes it easy to start experimenting with and training YOLOv8 models right from your computer. Let's dive deeper into JupyterLab, its key features, and how you can use it to train YOLOv8 models.

What is JupyterLab?

JupyterLab is an open-source web-based platform designed for working with Jupyter notebooks, code, and data. It's an upgrade from the traditional Jupyter Notebook interface that provides a more versatile and powerful user experience.

JupyterLab allows you to work with notebooks, text editors, terminals, and other tools all in one place. Its flexible design lets you organize your workspace to fit your needs and makes it easier to perform tasks like data analysis, visualization, and machine learning. JupyterLab also supports real-time collaboration, making it ideal for team projects in research and data science.

Key Features of JupyterLab

Here are some of the key features that make JupyterLab a great option for model development and experimentation:

• All-in-One Workspace: JupyterLab is a one-stop shop for all your data science needs. Unlike the classic Jupyter Notebook, which had separate interfaces for text editing, terminal access, and notebooks, JupyterLab integrates all these features into a single, cohesive environment. You can view and edit various file formats, including JPEG, PDF, and CSV, directly within JupyterLab. An all-in-one workspace lets you access everything you need at your fingertips, streamlining your workflow and saving you time.
• Flexible Layouts: One of JupyterLab's standout features is its flexible layout. You can drag, drop, and resize tabs to create a personalized layout that helps you work more efficiently. The collapsible left sidebar keeps essential tabs like the file browser, running kernels, and command palette within easy reach. You can have multiple windows open at once, allowing you to multitask and manage your projects more effectively.
• Interactive Code Consoles: Code consoles in JupyterLab provide an interactive space to test out snippets of code or functions. They also serve as a log of computations made within a notebook. Creating a new console for a notebook and viewing all kernel activity is straightforward. This feature is especially useful when you're experimenting with new ideas or troubleshooting issues in your code.
• Markdown Preview: Working with Markdown files is more efficient in JupyterLab, thanks to its simultaneous preview feature. As you write or edit your Markdown file, you can see the formatted output in real-time. It makes it easier to double-check that your documentation looks perfect, saving you from having to switch back and forth between editing and preview modes.
• Run Code from Text Files: If you're sharing a text file with code, JupyterLab makes it easy to run it directly within the platform. You can highlight the code and press Shift + Enter to execute it. It is great for verifying code snippets quickly and helps guarantee that the code you share is functional and error-free.

Why Should You Use JupyterLab for Your YOLOv8 Projects?

There are multiple platforms for developing and evaluating machine learning models, so what makes JupyterLab stand out? Let's explore some of the unique aspects that JupyterLab offers for your machine-learning projects:

• Easy Cell Management: Managing cells in JupyterLab is a breeze. Instead of the cumbersome cut-and-paste method, you can simply drag and drop cells to rearrange them.
• Cross-Notebook Cell Copying: JupyterLab makes it simple to copy cells between different notebooks. You can drag and drop cells from one notebook to another.
• Easy Switch to Classic Notebook View: For those who miss the classic Jupyter Notebook interface, JupyterLab offers an easy switch back. Simply replace /lab in the URL with /tree to return to the familiar notebook view.
• Multiple Views: JupyterLab supports multiple views of the same notebook, which is particularly useful for long notebooks. You can open different sections side-by-side for comparison or exploration, and any changes made in one view are reflected in the other.
• Customizable Themes: JupyterLab includes a built-in Dark theme for the notebook, which is perfect for late-night coding sessions. There are also themes available for the text editor and terminal, allowing you to customize the appearance of your entire workspace.

Common Issues While Working with JupyterLab

When working with Kaggle, you might come across some common issues. Here are some tips to help you navigate the platform smoothly:

• Managing Kernels: Kernels are crucial because they manage the connection between the code you write in JupyterLab and the environment where it runs. They can also access and share data between notebooks. When you close a Jupyter Notebook, the kernel might still be running because other notebooks could be using it. If you want to completely shut down a kernel, you can select it, right-click, and choose "Shut Down Kernel" from the pop-up menu.
• Installing Python Packages: Sometimes, you might need additional Python packages that aren't pre-installed on the server. You can easily install these packages in your home directory or a virtual environment by using the command python -m pip install package-name. To see all installed packages, use python -m pip list.
• Deploying Flask/FastAPI API to Posit Connect: You can deploy your Flask and FastAPI APIs to Posit Connect using the rsconnect-python package from the terminal. Doing so makes it easier to integrate your web applications with JupyterLab and share them with others.
• Installing JupyterLab Extensions: JupyterLab supports various extensions to enhance functionality. You can install and customize these extensions to suit your needs. For detailed instructions, refer to JupyterLab Extensions Guide for more information.
• Using Multiple Versions of Python: If you need to work with different versions of Python, you can use Jupyter kernels configured with different Python versions.
