How can I connect with tensorboard

This model is based on classification of 5 types of snakes and train using 17300 images and 11200 images for validation.So i cannot see performance of my model because cannot view any graph(for accuracy,loss,over fitting etc.) I want to visualize working flow of my model using tensorboard and how can i add that model to tensorboard,Any help will be highly appreciated.

Answer 1

The simple answer of why you cannot view the graph of accuracy, loss, overfitting, etc is because you're not doing any logging. Tensorflow will not automatically log things for you.

but I highly recommend you go through Tensorflow Mnist Example, try to implement how you think it should go and then reference Tensorflow MNIST with Tensorboard Example

If you want a quick start to the concepts look at quick introduction
