From a fresh install (curl https://ollama.ai/install.sh | sh on Ubuntu Linux 22.04) using ollama run codeup:13b-llama2-chat-q4_K_M, runs but when I try /show parameters, generates a segfault:

>>> /list

codeup:13b-llama2-chat-q4_K_M	d9c411941357	7.9 GB	12 hours ago	
>>> /show parameters
error: couldn't get model

@lstep commented on GitHub (Sep 27, 2023):

same for show system.
I checked, the model is correctly found as it answers (not correctly :-)):

ollama run codeup:13b-llama2-chat-q4_K_M
>>> I have three apples. I eat two pears. How many apples do I have left?
    
You have one apple left after eating two pears.
