python - Multiprocessing, file not found

Question

I'm using AlphaPose from GitHub and I'd like to run the script script/demo_inference.py from another script I created in AlphaPose root called run.py. In run.py I imported demo_inference.py as ap using this script:

def import_module_by_path(path): 
  name = os.path.splitext(os.path.basename(path))[0] spec = 
  importlib.util.spec_from_file_location(name, path) mod = 
  importlib.util.module_from_spec(spec) spec.loader.exec_module(mod) return mod

and

ap = import_module_by_path('./scripts/demo_inference.py')

Then, in demo_inference.py I substituted

if __name__ == "__main__": 

with

def startAlphapose(): 

and in run.py I wrote

ap.StartAlphapose().

Now I got this error:

What does it mean?
