How to use all GPUs for training

[dreamstorm25]

Hi, I have been trying to train on 2 gpus but I dont know how to specify both the GPUs. In the help it says if "all" then try to allocate on every gpu but using 'all' gives an error : ValueError : invalid literal for int() with base 10: all. Also specifying two numbers doesn't work. Can you please tell me how to use multiple GPUs ?

This is a good next feature request. Right now the testing code is multi-gpu but for training still single gpu. We are working on update with newer models and tf 2.2 that would allow us to distribute training. However this version may take time.
