I have the same problem. Have you solved it

[aligoglos]

I've got same error too !!!

[aligoglos]

I've solved it with these tricks : (its not good way but you could run it!)

1. first change config.py by replacing these lines:

            with tempfile.TemporaryDirectory() as temp_config_dir:
                temp_config_file = tempfile.NamedTemporaryFile(
                    dir=temp_config_dir, suffix='.py')
                temp_config_name = osp.basename(temp_config_file.name)
                des = osp.join(temp_config_dir, temp_config_name).replace('\\', '/')
                shutil.copyfile(filename,des)
                temp_module_name = osp.splitext(temp_config_name)[0]
                sys.path.insert(0, temp_config_dir)
                mod = import_module(temp_module_name)
                sys.path.pop(0)
                cfg_dict = {
                    name: value
                    for name, value in mod.__dict__.items()
                    if not name.startswith('__')
                }
                delete imported module
                del sys.modules[temp_module_name]
                close temp file
                temp_config_file.close()

with:

            mod = import_module('DetectoRS')
            sys.path.pop(0)
            cfg_dict = {
               name: value
               for name, value in mod.__dict__.items()
               if not name.startswith('__')
            }

and then copy config fime behind webcam_demo.py and renamed it with DetectoRS.py

Also got this problem. No idea what is the cause of this, but I solved it by changing two lines

This:
temp_config_file = tempfile.NamedTemporaryFile(dir=temp_config_dir, suffix='.py')

changed to this:
temp_config_file = tempfile.NamedTemporaryFile(dir=temp_config_dir, suffix='')

And:
shutil.copy(filename, osp.join(temp_config_dir, temp_config_name))

To:
shutil.copy(filename, osp.join(temp_config_dir, temp_config_name) + '.py')

No idea what is going on, but whenever suffix argument is different from actual file extension - everything works and every time file extension is the same as suffix argument I get this permission denied error.

[TimothyZero]

replace :

tempfile.NamedTemporaryFile(dir=temp_config_dir, suffix='.py')

with

tempfile.NamedTemporaryFile(dir=temp_config_dir, suffix='.py', delete=False)

it works for me
