How To Convert Udacity TXT to Tensorflow Object Detection CSV

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

Udacity TXT

The format used by the Udacity Self Driving Car dataset.

Below, learn the structure of Udacity TXT.

Step 2: Upload your data into Roboflow

Once your account has been created, click Create New Project. (opens in a new tab)

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

Upload your data to Roboflow by dragging and dropping your Udacity TXT images and annotations into the upload space.
