please try inserting train_kwargs['root'] = str(train_kwargs['root']) before train_data = dset(**train_kwargs) in dataset.py and see if it solves the problem

I replaced pathlib module with os and now I guess the above issue will not happen anymore. but if you still find any problem regarding this, please let me know. thanks.

[Hanzy1996]

Thanks a lot. I am downloading the datasets and will retry later.MUCH appreciation for replying timely.

[Hanzy1996]

It seems pathlib works better. I retry the code I downloaded yesterday on the server with python 2, and it is going well. But the code, in which you said you replaced pathlib module with os, I downloaded today has other bug. The bug still exists after I inserted train_kwargs['root'] = str(train_kwargs['root']) before train_data = dset(**train_kwargs) in dataset.py.

Traceback (most recent call last): File "/root/anaconda2/lib/python2.7/site-packages/visdom/init.py", line 446, in _send data=json.dumps(msg), File "/root/anaconda2/lib/python2.7/site-packages/requests/api.py", line 110, in post return request('post', url, data=data, json=json, kwargs) File "/root/anaconda2/lib/python2.7/site-packages/requests/api.py", line 56, in request return session.request(method=method, url=url, kwargs) File "/root/anaconda2/lib/python2.7/site-packages/requests/sessions.py", line 488, in request resp = self.send(prep, send_kwargs) File "/root/anaconda2/lib/python2.7/site-packages/requests/sessions.py", line 609, in send r = adapter.send(request, kwargs) File "/root/anaconda2/lib/python2.7/site-packages/requests/adapters.py", line 487, in send raise ConnectionError(e, request=request) ConnectionError: HTTPConnectionPool(host='localhost', port=8097): Max retries exceeded with url: /env/main (Caused by NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection object at 0x7f6578fb9c50>: Failed to establish a new connection: [Errno 111] Connection refused',)) No handlers could be found for logger "visdom" Traceback (most recent call last): File "main.py", line 69, in main(args) File "main.py", line 21, in main net = Solver(args) File "/data2/Hanzongyan/Beta-VAE/solver.py", line 126, in init os.makedirs(self.ckpt_dir, exist_ok=True) TypeError: makedirs() got an unexpected keyword argument 'exist_ok'

Maybe pathlib with inserting train_kwargs['root'] = str(train_kwargs['root']) is a better choice.

[1Konny]

are you using python2? I think your python version makes the problem. It seems that keyword argument 'exist_ok' is supported only in python3, but not in python2.

https://docs.python.org/2/library/os.html#os.makedirs https://docs.python.org/3/library/os.html#os.makedirs

Thanks so much. It finally works and I get the results after 8 hours' trainning.

Great! closing for now.
