lm harness distributed evaluation?

I am trying to eval the finetuned model 70B with torch run and getting error

Here is my config file

when tried with

it's giving another error

How to evaluate large models with torchtune?

[joecummings]

This is something we're working closely with the EleutherAI team on providing soon. For now, if you have enough RAM (and patience) you can try running on CPU - this will likely take a looooong time. You can also try using the accelerate library for now by following the instructions here: https://github.com/EleutherAI/lm-evaluation-harness#multi-gpu-evaluation-with-hugging-face-accelerate.

Stay tuned for a torchtune native multi-GPU evaluation feature soon!

[monk1337]

Awesome, and thank you for the reply! I am excited about the new feature, but in the meantime, I want to try the native LM harness. However, to do that, I need to convert TorchTune weights into HF weights. I am having issues with the conversion for the 70B model, so I have opened another issue for that. Please take a look when you have a chance. https://github.com/pytorch/torchtune/issues/922

I am a heavy user of Axolotl and TRL but am now switching to TorchTune. I anticipate encountering some bugs during this transition, so I will be opening issues as I come across them. :) Additionally, I would be happy to contribute in any way that I can.

An approach was proposed for multi-gpu eval via EleutherAI in #951
