I haven't seen this before. I tried installing litdb in a uv venv with python 3.13, but it was unable to resolve the package requirements.

Are you able to run ollama in a shell, eg

> ollama run llama2

Are you using a VPN? and a current version of ollama and the ollama python library?

[brioglade]

ollama run llama2 is normal. Yes, I used a VPN, and the settings are http_proxy and https_proxy. ollama version is 0.5.4. I downloaded ollama manually and used it directly.

[jkitchin]

packages/torch/lib/../../nvidia/cusparse/lib/libcusparse.so.12: undefined symbol: __nvJitLinkComplete_12_4, version libnvJitLink.so.12 means some library is either missing, the wrong version, etc. specifically related to nvidia, and here the libcusparse file. This is probably some kind of incompatibility with your pytorch / nvidia installation.

I don't know what the fix is, maybe it is a library path issue, or you have to reinstall some combination of torch, cuda, etc.
