run_inference.py FileNotFoundError

[WEXIJUE]

in main
with open(args.output_dir, "a") as wp:
FileNotFoundError: [Errno 2] No such file or directory: 'experiment/multiarith'
Does anyone know how to fix this error?
Thank you so much

'experiment/multiarith' is a output dir, perhaps you can manually add a folder named 'experiment/'
