Unable to execute comfyscript when called via function #65
Description
I am trying to write a script using comfyscript to generate images.
When the comfyscript is called using function it throws the following error:
Failed to validate prompt for output SaveImage.0:
* CheckpointLoaderSimple CheckpointLoaderSimple.0:
- Value not in list: ckpt_name: 'artium_v20Turboboosted.safetensors' not in (list of length 35)
Output will be ignored
invalid prompt: {'type': 'prompt_outputs_failed_validation', 'message': 'Prompt outputs failed validation', 'details': '', 'extra_info': {}}

Steps to reproduce:
- main.py : Executing main.py fails with the above error
import image
def main(name: str):
prompt = "Dark, misty forest with twisted tree branches like skeletal fingers reaching towards a full moon hanging low in the sky, casting an eerie glow on a worn dirt path that winds through the trees. The air is heavy with the scent of damp earth and decaying leaves. In the distance, a faint light flickers from a lantern hung outside a small, weathered cottage, its windows like empty eyes staring back at you."
image.generate_image(prompt, name)
if __name__ == "__main__":
main("story1")
- image.py: Executing image.py succeeds
from comfy_script.runtime import load, Workflow
load("comfyui")
from comfy_script.runtime.nodes import (
CheckpointLoaderSimple,
CLIPTextEncode,
EmptyLatentImage,
KSampler,
VAEDecode,
SaveImage,
)
negative_prompt = "ugly, deformed, noisy, blurry, noisy, low contrast (((bad anatomy))) watermark, bad hands, (((incomplete limbs))) ((((looking at viewer))))(((bad anatomy))) ((exaggerated anatomy))"
def generate_image(positive_prompt: str, output: str):
global negative_prompt
with Workflow():
model, clip, vae = CheckpointLoaderSimple("artium_v20Turboboosted.safetensors")
positive_conditioning = CLIPTextEncode(positive_prompt, clip)
negative_conditioning = CLIPTextEncode(negative_prompt, clip)
latent = EmptyLatentImage(1024, 576, 1)
latent = KSampler(
model,
156680208700286,
20,
7,
"dpmpp_2m",
"karras",
positive_conditioning,
negative_conditioning,
latent,
1,
)
image = VAEDecode(latent, vae)
SaveImage(image, output)
if __name__ == "__main__":
prompt = "Dark, misty forest with twisted tree branches like skeletal fingers reaching towards a full moon hanging low in the sky, casting an eerie glow on a worn dirt path that winds through the trees. The air is heavy with the scent of damp earth and decaying leaves. In the distance, a faint light flickers from a lantern hung outside a small, weathered cottage, its windows like empty eyes staring back at you."
generate_image(prompt, "story1")
I have tried to play around by moving load() and Workflow() to main.py but was facing the same issue.
Please help check if I am missing something.
Thanks for the help.
