Mastering Computer Vision with TensorFlow 2.x

The model.ckpt files

In this section, we will learn how to download the checkpoint file of the pre-trained model. Checkpoints are the weights of the model. These weights will be uploaded to the GCS bucket to initiate training using transfer learning:

1. Go to the TensorFlow Model Zoo GitHub page and download the appropriate model.tar file:

https://github.com/tensorflow/models/blob/master/research/object_detection/g3doc/detection_model_zoo.md

2. The following is the unzipped version of the appropriate file that we downloaded:

ssd_mobilenet_v1_0.75_depth_300x300_coco14_sync_2018_07_03.tar.gz

Checkpoints capture the exact value of all parameters used by the model. When you unzip the file, you will notice that there are the following types of files: ...
