Hello,

I am fine-tuning dolphin-mixtral with axolotl. I am inspired by your config, I chose qlora modules. What is interesting, that I can fine-tune dolphin-2.5-mixtral-8x7b, but when I just change "5" to "6" and otherwise keep the config the same (and remove and recreate the output directory), I get the following error:

RuntimeError: Expected all tensors to be on the same device, but found at least two devices, cuda:6 and cuda:0!

Any idea what could be different about 2.5 vs 2.6 that could cause this?
