你好，按照您的方法，运行test.py.我用的是CPU，在哪个ngpu那里设置为0，但是一运行的话就会出现下边的错误，您知道该怎么解决吗 D:\Anaconda\lib\site-packages\torchvision\transforms\transforms.py:207: UserWarning: The use of the transforms.Scale transform is deprecated, please use transforms.Resize instead. warnings.warn("The use of the transforms.Scale transform is deprecated, " + D:\Anaconda\lib\site-packages\torchvision\transforms\transforms.py:207: UserWarning: The use of the transforms.Scale transform is deprecated, please use transforms.Resize instead. warnings.warn("The use of the transforms.Scale transform is deprecated, " + Traceback (most recent call last): File "", line 1, in File "D:\Anaconda\lib\multiprocessing\spawn.py", line 105, in spawn_main exitcode = _main(fd) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 114, in _main prepare(preparation_data) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 225, in prepare _fixup_main_from_path(data['init_main_from_path']) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 277, in _fixup_main_from_path run_name="mp_main") File "D:\Anaconda\lib\runpy.py", line 263, in run_path pkg_name=pkg_name, script_name=fname) File "D:\Anaconda\lib\runpy.py", line 96, in _run_module_code mod_name, mod_spec, pkg_name, script_name) File "D:\Anaconda\lib\runpy.py", line 85, in _run_code exec(code, run_globals) File "C:\Users\LZZ\Downloads\context_encoder_pytorch-master\test.py", line 78, in Traceback (most recent call last): File "", line 1, in dataiter = iter(dataloader) File "D:\Anaconda\lib\site-packages\torch\utils\data\dataloader.py", line 819, in iter File "D:\Anaconda\lib\multiprocessing\spawn.py", line 105, in spawn_main exitcode = _main(fd) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 114, in _main prepare(preparation_data) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 225, in prepare return _DataLoaderIter(self) File "D:\Anaconda\lib\site-packages\torch\utils\data\dataloader.py", line 560, in init _fixup_main_from_path(data['init_main_from_path']) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 277, in _fixup_main_from_path run_name="mp_main") File "D:\Anaconda\lib\runpy.py", line 263, in run_path w.start() File "D:\Anaconda\lib\multiprocessing\process.py", line 112, in start pkg_name=pkg_name, script_name=fname) File "D:\Anaconda\lib\runpy.py", line 96, in _run_module_code self._popen = self._Popen(self) File "D:\Anaconda\lib\multiprocessing\context.py", line 223, in _Popen mod_name, mod_spec, pkg_name, script_name) File "D:\Anaconda\lib\runpy.py", line 85, in _run_code return _default_context.get_context().Process._Popen(process_obj) File "D:\Anaconda\lib\multiprocessing\context.py", line 322, in _Popen exec(code, run_globals) File "C:\Users\LZZ\Downloads\context_encoder_pytorch-master\test.py", line 78, in return Popen(process_obj) File "D:\Anaconda\lib\multiprocessing\popen_spawn_win32.py", line 33, in init dataiter = iter(dataloader) File "D:\Anaconda\lib\site-packages\torch\utils\data\dataloader.py", line 819, in iter prep_data = spawn.get_preparation_data(process_obj._name) File "D:\Anaconda\lib\multiprocessing\spawn.py", line 143, in get_preparation_data _check_not_importing_main() File "D:\Anaconda\lib\multiprocessing\spawn.py", line 136, in _check_not_importing_main is not going to be frozen to produce an executable.''')

    This probably means that you are not using fork to start your
    child processes and you have forgotten to use the proper idiom
    in the main module:

        if __name__ == '__main__':
            freeze_support()
            ...

    The "freeze_support()" line can be omitted if the program
    is not going to be frozen to produce an executable.

Hi, Don't know if still relevant, but I replaced all transforms.Scale at train.py with transforms.Resize, and moved all code in train.py to a if __name__ == '__main__': block, and resoved this 2 issues
