Hi, all

There are some issues from Ollama:

  1. Skip GPU discovery → fallback to CPU
  2. Sandbox was configured with contextWindow=4096 → caused “Context overflow” error

After applying the settings below, we can get NemoClaw running without issue.

  1. Edit /etc/systemd/system/ollama.service.d/override.conf
[Service]
Environment="OLLAMA_HOST=127.0.0.1:11434"
Environment="OLLAMA_CONTEXT_LENGTH=32768"
Environment="OLLAMA_IGPU_ENABLE=1"
Environment="GGML_BACKEND_PATH=/usr/local/lib/ollama/cuda_v13/libggml-cuda.so"
Environment="LD_LIBRARY_PATH=/usr/local/lib/ollama:/usr/local/lib/ollama/cuda_v13"

$ sudo systemctl daemon-reload
$ sudo systemctl restart ollama
  1. Edit openclaw setting
$ nemoclaw my-assistant connect
# sed -i.bak 's/"contextWindow"[[:space:]]*:[[:space:]]*4096/"contextWindow": 32768/' .openclaw/openclaw.json
# sha256sum .openclaw/openclaw.json > .openclaw/.config-hash 
# openclaw tui

Thanks
