@adityaee87 hi there! 👋 When training YOLOv5 on multiple GPUs, it is normal for each GPU to use less memory compared to training with a single GPU. This is because the model parameters are divided and processed independently on each GPU, reducing the memory required per GPU. Regarding your SLURM job submission, it looks like you are correctly allocating both CPUs and two GPUs. However, setting If you are experiencing any other issues or have further questions, please let us know. We're here to help! |
Thanks for your response @glenn-jocher but training with both 1GPU or 2GPU lead to same training speed.Is there way around it. |
@adityaee87, thank you for your feedback. If training with both 1 GPU and 2 GPUs results in the same training speed, it could be due to other factors affecting the training process. Here are a few suggestions to potentially improve the training speed:
Please let us know if you have any other questions or if there's anything else we can assist you with. We're here to help you get the most out of YOLOv5! |
Thanks @glenn-jocher |
@adityaee87 hi there! It seems that you are experiencing an issue with training YOLOv5 on multiple GPUs where the training speed remains the same regardless of using 1 or 2 GPUs. There could be several factors contributing to this issue. Here are a few suggestions to consider:

Question
I am trying to speed up training on YoloV5.But when I am using 2 GPUs for training instead of speeding the training it is rather using half the GPU memory it was using during the training with 1 GPU. I do not know whether my fault or not because I'm submitting my job using SLURM where I ask to allocate 1 CPU and 2 gpus. Also, I have to set OMP_NUM_THREADS = 2 during training.
