How To Convert Google Cloud AutoML Vision CSV to YOLOv7 PyTorch TXT

In this guide, we show you how to convert data between the AutoML Vision and YOLOv7 formats for free. You can use your converted data to train YOLOv9 models and other models that support the YOLOv7 format.

Google Cloud AutoML Vision CSV

The CSV format needed for Google's AutoML Vision tool.

Below, learn the structure of Google Cloud AutoML Vision CSV.

YOLOv7 PyTorch TXT

A modified version of YOLO Darknet annotations that adds a YAML file for model config.

Below, learn the structure of YOLOv7 PyTorch TXT.

Each image has one txt file with a single line for each bounding box. The format of each row is

class_id center_x center_y width height

where fields are space delimited, and the coordinates are normalized from zero to one.

Note: To convert to normalized xywh from pixel values, divide x (and width) by the image's width and divide y (and height) by the image's height.

Step 1: Create a free Roboflow public workspace

Roboflow is a universal conversion tool for computer vision annotation formats. The Public plan is the best way for those exploring personal projects, class assignments, and other experiments to try Roboflow. To convert your dataset, start by creating a free workspace on the Public plan.

Create Roboflow Workspace

Step 2: Upload your data into Roboflow

Once your account has been created, click Create New Project.

Roboflow's create project form, with Object Detection selected as the project type

Upload your data to Roboflow by dragging and dropping your Google Cloud AutoML Vision CSV images and annotations into the upload space.

Roboflow's upload page, with a drag-and-drop area for images, annotations, videos and PDFs

Step 3: Generate Dataset Version

Next, click "Generate New Version" to generate a new version of your dataset:

Roboflow's Generate a Dataset Version page, showing the source images and train/test split for a new version

You can then apply any preprocessing or augmentation steps to your dataset:

Step 4: Export Dataset Version

After generating, you will be prompted to Export your dataset. You can choose to receive your dataset as a .zip file or a curl download link. Choose YOLOv7 PyTorch TXT when asked in what format you want to export your data. You will see a dropdown with various options like this:

Roboflow's Download dialog, with the export format list open and COCO highlighted

Congratulations, you have successfully converted your dataset from Google Cloud AutoML Vision CSV format to YOLOv7 PyTorch TXT format!

Frequently Asked Questions

Yes! It is free to convert Google Cloud AutoML Vision CSV data into the YOLOv7 PyTorch TXT format on the Roboflow platform.

If you have between a few and a few thousand images, converting data between these formats will be quick. But, the time it takes to convert between data formats increases with the more images you have.
