How long does tensorflow object detection API train.py complete training using CPU only?

Question

I am a beginner in machine learning. Recently, I had successfully running a machine learning application using Tensorflow object detection API. My dataset is 200 images of object with 300*300 resolution. However, the training had been running for two days and yet to be completed.

I wonder how long would it take to complete a training?? At the moment it is running at global step 9000, how many global step needed to complete the training?

P.S: the training used only CPUs

Answer 1

It depends on your desired accuracy and data set of course but I generally stop training when the loss value gets around 4 or less. What is your current loss value after 9000 steps?
