Tensorflow comes with example code to retrain Inception's final layer for new image categories. The code is found here [login to view URL] and the description here [login to view URL]
The code in [login to view URL] is only able to use one GPU even on a machine with several GPUs. I need it to be modified to be able to use all the GPUs on a machine in order to accelerate the training. The modified script must also accept a flag to have it use a specific number of GPUs.
