Running TensorBoard: tensorboard --logdir=PATH PATH is the path where the graphs are stored, ex: C:\Users\andri\machine_learning\source\01_TensorFlow\graphs It shouldn't be spaces between 'logdir and =' and '= and PATH' TensorBoard is runnning on localhost port 6006: localhost:6006 (or currently for me the address is: http://desktop-pq5sbmt:6006)
