Description
### Proposal:
Currently I get in Manticore 17.5
prealloc: Failed to download model weights
while trying to use a bigger model (eg Qwen 4B).
I have no idea why I get this message, it doesnt explain the problem. The available RAM is 80G+, so I should be able to run most models.
Request: improve this errormessage:
- why can I not download the weight
- what is required for resources
- what I currently have for resources
