Getting winerror 3 filenotfounderror in basicsr\\archs after generating exe file by pyinstaller in python

Question

I'm using BasicSR in my one of the desktop application. and It's working and running fine on PyCharm.

But after converting it to EXE file using pyinstaller, I'm getting below error.

I think it can be os.scandir, but how can I solve this, I don't know..

please help me to resolve this as I've already spent a lot time..

hook-basicsr.py file

Thanks in advance..

I solved this problem by replacing the content of basicsr/archs/__init__.py with the following. And do the same operation for those who use scandir in __init__.py.

import importlib
from copy import deepcopy
from os import path as osp

from basicsr.utils import get_root_logger, scandir
from basicsr.utils.registry import ARCH_REGISTRY

__all__ = ['build_network']

# automatically scan and import arch modules for registry
# scan all the files under the 'archs' folder and collect files ending with
# '_arch.py'
# arch_folder = osp.dirname(osp.abspath(__file__))
# arch_filenames = [osp.splitext(osp.basename(v))[0] for v in scandir(arch_folder) if v.endswith('_arch.py')]
# # import all the arch modules
# _arch_modules = [importlib.import_module(f'basicsr.archs.{file_name}') for file_name in arch_filenames]

def build_network(opt):
    opt = deepcopy(opt)
    network_type = opt.pop('type')
    net = ARCH_REGISTRY.get(network_type)(**opt)
    logger = get_root_logger()
    logger.info(f'Network [{net.__class__.__name__}] is created.')
    return net
