FAQ

“Command not found” after installing

Tools like Git, Python, and Ollama are installed but PowerShell can’t find them.

Fix: Close all PowerShell windows and open a new one. Windows updates PATH when software is installed, but already open windows don’t reload it.

If you still see the error, verify the tool is actually installed:

where git
where python
where ollama

If where doesn’t find it, run the install script again.

Scripts won’t run (“not digitally signed”)

PowerShell blocks scripts downloaded from the internet.

Fix:

Unblock-File *.ps1
Set-ExecutionPolicy -Scope CurrentUser RemoteSigned

Only needed once after downloading.

Venv activation blocked

PowerShell’s execution policy prevents running the activation script.

Fix:

Set-ExecutionPolicy -Scope CurrentUser RemoteSigned

Or use the full path to Python:

.\venv\Scripts\python.exe main.py

ComfyUI shows “Torch not compiled with CUDA enabled”

The CUDA version of PyTorch was installed but your AMD GPU can’t use it.

Fix: Re-run the install:

ai install comfyui

The script detects the AMD GPU, recreates the venv, and installs torch-directml.

Symbolic links fail

mklink requires Administrator rights or Developer Mode.

Fix: Run PowerShell as Administrator, or enable Developer Mode:

• Windows 11: Settings → Privacy & Security → For Developers → Developer Mode
• Windows 10: Settings → Update & Security → For Developers → Developer Mode

Open Web UI won’t start (port in use)

Shows [Errno 10048] error while attempting to bind on address.

Fix: Change the port:

ai setup ports

Set Open Web UI to a different port, then restart.

Pip version notice

[notice] A new release of pip is available: 24.0 -> 26.1.2

A notification, not an error. The pip version that comes with Python 3.11 works perfectly. Ignore it.

“Skipped (already up to date)” in install summary

Install Summary
  Git: Skipped (already up to date)

Normal - means the tool was already installed with no newer version available.

FFmpeg shows “not found” in doctor

Ran 2-deps.ps1 but doctor still reports FFmpeg missing.

Fix: Restart PowerShell. The current window doesn’t see the PATH update.

Models are gone after setting OLLAMA_MODELS

The variable was set after pulling models, so they’re still in the old location.

Fix: Set OLLAMA_MODELS before pulling. Old models at C:\Users\<you>\.ollama\models\blobs can be deleted to free space.

AMD driver instability (Adrenalin 26.5.x / 26.6.1)

Some RX 7000 and 9000 series users report system-wide freezes with newer AMD drivers - even during basic desktop tasks, not just AI workloads. The RX 7000 series is the primary AMD platform for this stack, and Adrenalin 26.3.1 is the recommended stable version for AI, gaming, and daily use.

Fix: Roll back to 26.3.1 if you hit freezes or crashes, especially in games or GPU-heavy apps.

See the full breakdown in KNOWN_ISSUES.md.

Venv keeps getting recreated

The script detected an AMD GPU with CUDA torch installed and recreates the venv. Intentional - prevents the “Torch not compiled with CUDA” crash.

Can I move the AI root after setup?

Update the path in AI_CONFIG\system_config.json, re-run ai setup env, then re-run ai install comfyui to regenerate launcher scripts with the new paths.
