Question about implementation results in table 2

Thanks for your open-source spirit!

I found a phenomenon that when I use multi-ple GPUs to run your code, it seems can correctly load the dataset, which make code stuck in:
Using 2 GPUs
Reading split from /fred/oz305/haojiang/code/a_lafter_code/data/stanford_cars/split_zhou_StanfordCars.json
Training Epoch 1/15: 0%|
Could you share the code that use mutiple GPUs?
