We are aware of the current limitations in the API: don’t put one of the first weights on GPU 0, then weights on GPU 1 and the last weight back to GPU 0) to avoid making many transfers of data between the GPUs.

To be the most efficient, make sure your device map puts the parameters on the GPUs in a sequential manner (e.g. You can also design your device_map yourself if you prefer to explicitly decide where each layer should be. Let’s download the sharded version of this model. Here is how we can use this to load the GPT2-1.5B model.

If you want to use big model inference with 🤗 Transformers models, check out this documentation. It will also automatically dispatch those weights across the devices you have available (GPUs, CPU RAM), so if you are loading a sharded checkpoint, the maximum RAM usage will be the size of the biggest shard. This supports full checkpoints (a single file containing the whole state dict) as well as sharded checkpoints. The second tool 🤗 Accelerate introduces is a function load_checkpoint_and_dispatch(), that will allow you to load a checkpoint inside your empty model. But at least one other user had Darrin's experience, where it crashed every time without fail.Copied Īnd first_state_dict.bin containing the weights for 'linear1.weight' and 'linear1.bias', second_state_dict.bin the ones for 'linear2.weight' and 'linear2.bias' Loading weights Most users are like Munkeh, where they can play fine without issues. Munkeh said the map 'took me 3 tries' so they must of started it three times, wheres Darrin said it crashed every time he tried to start it which implies multiple launches.

Compare the comments of Munkehboi and Darrin.Woodlee in that Map's comment section. I also know from comments on the map that it was only SOME users experincing this issue. If you have need of it, I can provide you a version of that map which I know some users have had issues with. I don't know which maps Ambi has made, but I've had a minority of users report crashes on startup in my map 'From the Ashes' which I've never experienced myself. OTHER people customs maps have Frozen on ME.Ĭould you please give me the name of the map you made and other users have suffered freezes with. MY Custom map has never froze on ME but my custom map HAS frozen for OTHERS.

They are billions custom map lagging
