Yesterday，it works correctly! but today,when I run the train.py.it reports as follows: pygame 1.9.6 Hello from the pygame community. https://www.pygame.org/contribute.html ========== DonkeyVae-v0-level-0 sac ========== Loading VAE ...

I want to know how to slove the problem. please help!😊

The above problem has been solved.But I meet a new problem: when I train the VAE by run"python -m vae.train --n-epochs 50 --verbose 0 --z-size 64 -f C:\Users\Administrator\Desktop\learning\record‘。it reports as follows: raceback (most recent call last): File "", line 1, in Traceback (most recent call last): File "C:\ProgramData\Anaconda3\envs\learning\lib\runpy.py", line 193, in _run_module_as_main "main", mod_spec) File "C:\ProgramData\Anaconda3\envs\learning\lib\runpy.py", line 85, in _run_code File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\spawn.py", line 105, in spawn_main exec(code, run_globals) File "C:\Users\Administrator\Desktop\learning\vae\train.py", line 63, in exitcode = _main(fd) File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\spawn.py", line 114, in _main data_loader = DataLoader(minibatchlist, images, n_workers=2, folder=args.folder) File "C:\Users\Administrator\Desktop\learning\vae\data_loader.py", line 129, in init prepare(preparation_data) File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\spawn.py", line 223, in prepare self.start_process() File "C:\Users\Administrator\Desktop\learning\vae\data_loader.py", line 154, in start_process _fixup_main_from_name(data['init_main_from_name']) File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\spawn.py", line 249, in _fixup_main_from_name self.process.start() File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\process.py", line 112, in start alter_sys=True) File "C:\ProgramData\Anaconda3\envs\learning\lib\runpy.py", line 205, in run_module self._popen = self._Popen(self) File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\context.py", line 223, in _Popen return _run_module_code(code, init_globals, run_name, mod_spec) File "C:\ProgramData\Anaconda3\envs\learning\lib\runpy.py", line 96, in _run_module_code return _default_context.get_context().Process._Popen(process_obj) File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\context.py", line 322, in _Popen mod_name, mod_spec, pkg_name, script_name) File "C:\ProgramData\Anaconda3\envs\learning\lib\runpy.py", line 85, in _run_code exec(code, run_globals) return Popen(process_obj) File "C:\Users\Administrator\Desktop\learning\vae\train.py", line 70, in File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\popen_spawn_win32.py", line 89, in init for obs in data_loader: reduction.dump(process_obj, to_child) NameError: name 'data_loader' is not defined File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\reduction.py", line 60, in dump ForkingPickler(file, protocol).dump(obj) BrokenPipeError: [Errno 32] Broken pipe Exception ignored in: <function DataLoader.del at 0x000002B103C82048> Traceback (most recent call last): File "C:\Users\Administrator\Desktop\learning\vae\data_loader.py", line 229, in del File "C:\ProgramData\Anaconda3\envs\learning\lib\multiprocessing\process.py", line 124, in terminate AttributeError: 'NoneType' object has no attribute 'terminate' 0%| my environments are windows10, anaconda, python3.7.6. please help me!

Oh，finally。I found the key to the problem。The Process object can only be created under“if name == 'main'”。so I try to write the "vae\data_loader.py(Data_loader(start_process))"as follows:

def start_process(self):
    print("loading....")
if __name__=='__main__':
    start_process()
    """Start preprocessing process"""
    self.process = Process(target=self._run)
    # Make it a deamon, so it will be deleted at the same time
    # of the main process
    self.process.daemon = True
    self.process.start()

No errors occurs.But it seems not work corrrectly!Processing is always at 0% So what can I to make it correct? I'm desperate for help!
