# A Step-by-Step Guide to Training YOLOv8 Models with IBM Watsonx
Nowadays, scalable [computer vision solutions](../guides/steps-of-a-cv-project.md) are becoming more common and transforming the way we handle visual data. A great example is IBM Watsonx, an advanced AI and data platform that simplifies the development, deployment, and management of AI models. It offers a complete suite for the entire AI lifecycle and seamless integration with IBM Cloud services.
You can train [Ultralytics YOLOv8 models](https://github.com/ultralytics/ultralytics) using IBM Watsonx. It's a good option for enterprises interested in efficient [model training](../modes/train.md), fine-tuning for specific tasks, and improving [model performance](../guides/model-evaluation-insights.md) with robust tools and a user-friendly setup. In this guide, we'll walk you through the process of training YOLOv8 with IBM Watsonx, covering everything from setting up your environment to evaluating your trained models. Let's get started!
[Watsonx](https://www.ibm.com/watsonx) is IBM's cloud-based platform designed for commercial generative AI and scientific data. IBM Watsonx's three components - watsonx.ai, watsonx.data, and watsonx.governance - come together to create an end-to-end, trustworthy AI platform that can accelerate AI projects aimed at solving business problems. It provides powerful tools for building, training, and [deploying machine learning models](../guides/model-deployment-options.md) and makes it easy to connect with various data sources.

Its user-friendly interface and collaborative capabilities streamline the development process and help with efficient model management and deployment. Whether for computer vision, predictive analytics, natural language processing, or other AI applications, IBM Watsonx provides the tools and support needed to drive innovation.
IBM Watsonx is made of three main components: watsonx.ai, watsonx.data, and watsonx.governance. Each component offers features that cater to different aspects of AI and data management. Let's take a closer look at them.
Watsonx.ai provides powerful tools for AI development and offers access to IBM-supported custom models, third-party models like [Llama 3](https://www.ultralytics.com/blog/getting-to-know-metas-llama-3), and IBM's own Granite models. It includes the Prompt Lab for experimenting with AI prompts, the Tuning Studio for improving model performance with labeled data, and the Flows Engine for simplifying generative AI application development. Also, it offers comprehensive tools for automating the AI model lifecycle and connecting to various APIs and libraries.
Watsonx.data supports both cloud and on-premises deployments through the IBM Storage Fusion HCI integration. Its user-friendly console provides centralized access to data across environments and makes data exploration easy with common SQL. It optimizes workloads with efficient query engines like Presto and Spark, accelerates data insights with an AI-powered semantic layer, includes a vector database for AI relevance, and supports open data formats for easy sharing of analytics and AI data.
Watsonx.governance makes compliance easier by automatically identifying regulatory changes and enforcing policies. It links requirements to internal risk data and provides up-to-date AI factsheets. The platform helps manage risk with alerts and tools to detect issues such as [bias and drift](../guides/model-monitoring-and-maintenance.md). It also automates the monitoring and documentation of the AI lifecycle, organizes AI development with a model inventory, and enhances collaboration with user-friendly dashboards and reporting tools.
## How to Train YOLOv8 Using IBM Watsonx
You can use IBM Watsonx to accelerate your YOLOv8 model training workflow.
You need an [IBM Cloud account](https://cloud.ibm.com/registration) to create a [watsonx.ai](https://www.ibm.com/products/watsonx-ai) project, and you'll also need a [Kaggle](./kaggle.md) account to load the data set.
First, you'll need to set up an IBM account to use a Jupyter Notebook. Log in to [watsonx.ai](https://eu-de.dataplatform.cloud.ibm.com/registration/stepone?preselect_region=true) using your IBM Cloud account.
Then, create a [watsonx.ai project](https://www.ibm.com/docs/en/watsonx/saas?topic=projects-creating-project), and a [Jupyter Notebook](https://www.ibm.com/docs/en/watsonx/saas?topic=editor-creating-managing-notebooks).
Once you do so, a notebook environment will open for you to load your data set. You can use the code from this tutorial to tackle a simple object detection model training task.
### Step 2: Install and Import Relevant Libraries
Next, you can install and import the necessary Python libraries.
!!! Tip "Installation"
=== "CLI"
```bash
# Install the required packages
pip install torch torchvision torchaudio
pip install opencv-contrib-python-headless
pip install ultralytics==8.0.196
```
For detailed instructions and best practices related to the installation process, check our [Ultralytics Installation guide](../quickstart.md). While installing the required packages for YOLOv8, if you encounter any difficulties, consult our [Common Issues guide](../guides/yolo-common-issues.md) for solutions and tips.
Then, you can import the needed packages.
!!! Example "Import Relevant Libraries"
=== "Python"
```python
# Import ultralytics
import ultralytics
ultralytics.checks()
# Import packages to retrieve and display image files
```
### Step 3: Load the Data
For this tutorial, we will use a [marine litter dataset](https://www.kaggle.com/datasets/atiqishrak/trash-dataset-icra19) available on Kaggle. With this dataset, we will custom-train a YOLOv8 model to detect and classify litter and biological objects in underwater images.
We can load the dataset directly into the notebook using the Kaggle API. First, create a free Kaggle account. Once you have created an account, you'll need to generate an API key. Directions for generating your key can be found in the [Kaggle API documentation](https://github.com/Kaggle/kaggle-api/blob/main/docs/README.md) under the section "API credentials".
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.

</p>
### 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:
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"
```python
# 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
- **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](../modes/train.md). This guide will help you get the most out of your experiments and ensure you're using YOLOv8 effectively.
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"
```python
# 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.
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](https://developer.ibm.com/tutorials/awb-train-yolo-object-detection-model-in-python/) for more details.
