Mixtral 8x7B full finetune with DS zero3: Assertion error #954

Open casper-hansen opened 9 months ago

casper-hansen commented 9 months ago

Please check that this issue hasn't been reported before.

Expected Behavior

That the model can start training after the DeepSpeed fix on main.

Current behaviour

The model loads and does not OOM, but DeepSpeed raises an assertion on checking that the datatype is the same for all tensors:

assert len(set(t.dtype for t in tensors)) == 1

I have faced hang issues after 1:30 hours training time wiht ft and zero3

codybum commented 9 months ago

With the same config I get OOM while training on 5 x nodes with 8 x H100 each.

Any configs other than the example 4-bit qlora I have tried results in a OOM or some other error.

u can try to update nccl 2.19.3

DhruvaBansal00 commented 6 months ago

Any updates on this error? I am seeing the same thing with Llama-v2 full finetune using zero3.

casper-hansen commented 6 months ago

I think this was solved by setting bf16 from auto to true instead in your deepspeed config

NanoCode012 commented 5 months ago

Does anyone still have this issue after trying casper's suggestion?
