Nothing is generated in the model folder? Can you provide more details on what's being printed?

name 10 animals similar to duck. Here are 10 animals that are similar to ducks:

1. Geese - Geese are similar to ducks in many ways, but they are generally larger and have longer necks.

2. Swans - Swans are larger than ducks and have a more slender, graceful appearance.

3. Coots - Coots are small to medium-sized birds that are similar to ducks in many ways, but they have a more rounded body shape and a distinctive red beak.

4. Grebes - Grebes are small to medium-sized birds that are similar to ducks in many ways, but they have a more slender body shape and a distinctive long neck.

5. Mergansers - Mergansers are small to medium-sized birds that are similar to ducks in many ways, but they have a more slender body shape and a distinctive black and

10. Ostrich HM Revenue & Customs (HMRC) is the UK’s tax, payments and customs authority. Its purpose is to collect taxes, pay benefits, and manage national insurance. HMRC also enquires into and investigates tax evasion and avoidance.

How does HMRC collect taxes?
HMRC collects taxes through various methods, including:

1. PAYE (Pay As You Earn) - employers deduct tax and National Insurance contributions from their employees' wages and pay them over to HMRC.
2. Self Assessment - individuals who are self-employed or have

The performance here is a lot lower than I'd expect. What GPU are you using?

As for the quantization note, perhaps the issue is that you're running out of CPU memory at some point during the process? I don't see any reason why the quantization script would stop in the middle.

[rraulison]

I am using iGPU from ryzen 5600g CPU.

Yes, to quantize I must have more memory. Thanks.

[petrex]

The error seems irrelevant to GPU. Also the AMD iGPU is not a viable accelerated back-end for pytorch atm.
