The trained Object Detection models can be run on mobile and edge devices to execute predictions really fast. device("/gpu:1"): # To run the matmul op we call the session 'run()' method, passing 'product' # which represents th. Annotating images and serializing the dataset. The code can be summarised as follows:. When we are working with a lot data, it is important to work with a format that is light and fast, one option is to work with the document's binary, which is exactly what TFRecords does, but in addition it is optimized for working with Tensorflow because it was created for Tensorflow, for example when you are working with a very large dataset. Indeed the Tensorflow Object Detection APIs underwent a lot of changes lately so several of the *. Installing these on the Raspberry Pi is a little different to installing them on desktop Unix-like environments, so take care that any tutorials you're following are going to be.
