Basic usage: resolve CUDA wheel and use process isolation.

from comfy_env import ComfyEnvManager, isolation_context # Resolve CUDA wheel for current environment manager = ComfyEnvManager() wheel_path = manager.resolve_cuda_wheel() print(f"Resolved wheel: {wheel_path}") # Run code in isolated subprocess with isolation_context(): # Your isolated code here pass

comfy-env --version

Debug

Known issues

breakingIn v0.3.0, the main class was renamed from EnvManager to ComfyEnvManager. Old imports will break.

fix

Use 'from comfy_env import ComfyEnvManager' instead of 'from comfy_env import EnvManager'.

affects: >=0.3.0

breakingIn v0.2.0, the isolation function was renamed from process_isolation to isolation_context.

fix

Use 'from comfy_env import isolation_context' instead of 'from comfy_env import process_isolation'.

affects: >=0.2.0

gotchaThe CUDA wheel resolution requires torch to be installed in the environment; otherwise it will raise an error.

fix

Ensure torch is installed before calling resolve_cuda_wheel().

affects: all
